. Effective text region extraction and binarization of image embedded text documents on mobile devices having limited computational resources is an open research problem. In this paper, we present one such technique for preprocessing images captured with built-in cameras of handheld devices with an aim of developing an efficient Business Card Reader. At first, the card image is processed for isolating foreground components. These foreground components are classified as either text or non-text using different feature descriptors of texts and images. (...) The non-text components are removed and the textual ones are binarized with a fast adaptive algorithm. Specifically, we propose new techniques for foreground component isolation, text extraction and binarization of text regions from camera captured business card images. Experiments with business card images of various resolutions show that the present technique yields better accuracy and involves low computational overhead in comparison with the state-of-the-art. We achieve optimum text/non-text separation performance with images of resolution 800×600 pixels with an average recall rate of 93.90% and a precision rate of 96.84%. It involves a peak memory consumption of 0.68 MB and processing time of 0.102 seconds on a moderately powerful notebook, and 4 seconds of processing time on a PDA. (shrink)

This book deals with the question of understanding religion and its relationship with politics in the context of developing countries. It reviews specific theories, such as modernisation theory, marxism, liberalism, hermeneutics and critical approach to explain questions related to religion and religious traditions. The book focuses on the recent attempts to theorise religion by Jurgen Habermas. It argues modernisation and orthodox Marxian theory are inadequate in understanding the recent spurt of religious phenomenon in politics. It discusses Hans-Georg Gadamer’s view to (...) show a way forward regarding dialectical hermeneutics in facilitating a dialogue between different traditions and religions. The book is of interest to students, scholars, practitioners of development, and all those who concern themselves with the questions of religion, tradition, modernity and secular well-being in developing countries such as India and beyond.

The integration of biomedical terminologies is indispensable to the process of information integration. When terminologies are linked merely through the alignment of their leaf terms, however, differences in context and ontological structure are ignored. Making use of the SNAP and SPAN ontologies, we show how three reference domain ontologies can be integrated at a higher level, through what we shall call the OBR framework (for: Ontology of Biomedical Reality). OBR is designed to facilitate inference across the boundaries of domain ontologies (...) in anatomy, physiology and pathology. (shrink)

The past 15 years occasioned an extraordinary blossoming of research into the cognitive and affective mechanisms that support moral judgment and behavior. This growth in our understanding of moral mechanisms overshadowed a crucial and complementary question, however: How are they learned? As this special issue of the journal Cognition attests, a new crop of research into moral learning has now firmly taken root. This new literature draws on recent advances in formal methods developed in other domains, such as Bayesian inference, (...) reinforcement learning and other machine learning techniques. Meanwhile, it also demonstrates how learning and deciding in a social domain—and especially in the moral domain—sometimes involves specialized cognitive systems. We review the contributions to this special issue and situate them within the broader contemporary literature. Our review focuses on how we learn moral values and moral rules, how we learn about personal moral character and relationships, and the philosophical implications of these emerging models. (shrink)

An increasing number of large corporations find themselves caught between two seemingly contradictory goals: satisfying investors’ expectations for progressive earnings’ growth and the stakeholders’ growing demand for ethical conduct. There is an increasing realization across geographies concerning the growing relevance of resolving this issue. The present article is a tool kit for business organizations who want to become ethically fit. The article exhibits the dilemma faced by the corporate world regarding embracing ethics in business. It attempts to establish with the (...) help of some empirical findings that on a broader canvas ethical conduct is contributory towards the bottom line growth. It also suggests that to evaluate the performance of a business the frame of reference has to be changed. Further, it offers tangible suggestions as to what business corporations ought to do in order to get ethically fit. (shrink)

The paper has two main parts. The first part is devoted to the traditional Hindu viewpoint on the existence and permanence of the self as an immaterial substance. Various arguments offered by Hindu philosophers against the materialist view that the body is the self as well as arguments against the Buddhist view of the self as a stream of constantly changing states are discussed critically with reference to recent philosophical perspectives. The second part is devoted to the doctrine of karma (...) and rebirth. A number of traditional arguments for the doctrine are studied analytically and critically as well as relevance of the doctrine for addressing the problem of evil that for many is a serious issue facing the creationist position. Finally, the major arguments of Plato who also held that the self is eternal and goes through reincarnation are critiqued from a comparative standpoint. (shrink)

The Buddhist argues that when two cognitive states are different, their objects are also different. For example, awareness of a pot is different from awareness of a cloth and their objects are different as well. Based on the pervasion that no two different cognitive states have the same object the Buddhist claims that the objects of inference and testimony on the one hand are different from the objects of (indeterminate) perception on the other. That is, what is perceived is never (...) the same as what is inferred or learnt from testimony. This lends support to the Buddhist position that only unique particulars that are grasped in (indeterminate) perception are real; what are grasped in inference or testimony are not unique particulars and, accordingly, are not real. Udayana’s critique of the above position is explained and analyzed. (shrink)

One approaching a thing from a distance may perceive it as existent, then as a substance, then as a tree and, finally, as a fig tree. Thus, the same fig tree can be the object of all these different perceptions. This shows, Udayana argues, that difference in cognitive states does not necessarily prove that their objects are different. This argument is in response to the Buddhist claim that since perceptual cognitive states and non-perceptual cognitive states are different, their respective objects (...) are also different; unique particulars (svalakSaNa) that alone are real, are grasped in perception; general features (saamaanyalakSaNa) that are not real are grasped in non-perceptual cognitive states. The Buddhist objects: when the same thing appears to be the object of different cognitive states, only that cognitive state which leads to useful result is reliable. Udayana replies: More than one cognitive state in the above situation may lead to useful result; it is not justified to accept only one of them as reliable and reject the others. The Buddhist objects again: perceptual awareness is direct but non-perceptual awareness is indirect: hence their objects are different. Udayana replies: The same thing may be perceived when there is sensory connection with it and then inferred from an invariably connected sign when there is no sensory connection. Thus, the same thing may be the object of both direct and indirect cognitive states depending on different causal conditions. (shrink)

In an episode in the Bhagavadgita Arjuna refuses to fight that would involve killing his teachers, elders, relatives and friends. Krishna argues that he should fight because it is the special duty of a soldier to fight in a just war, one should do one’s duty regardless of the consequences, one should act for the common good, one should build an unwavering character taking victory and defeat, pleasure and pain, friend and foe in the same way, etc. Some of these (...) reasons may be taken to promote deontology, others utilitarianism, yet others virtue ethics that are often viewed contemporarily as incompatible ethical theories. We argue that these three theories are not necessarily incompatible and may be linked to three sides of human nature: deontology to cognitivity, utilitarianism to dynamism and virtue ethics to affectivity. We also argue that Krishna may be taken to promote ethical pluralism just as he may be taken to promote religious pluralism by recommending the path of knowledge, the path of action and the path of devotion from an inclusive perspective.

On the tenets of Sankhya philosophy in the light of Vijnanabhiksu's bhāṣya and Yoga varttika.

Counterinference is one of five kinds of pseudo-prover (similar to fallacy in Western logic) recognized in the Nyaaya school. Typically in counterinference while one side seeks to prove the thesis that a probandum belongs to an inferential subject because an inferential mark pervaded by the probandum belongs to that subject, an opponent challenges that by arguing that the probandum does not belong to the inferential subject because another inferential mark pervaded by absence (negation) of the probandum belongs to that subject. (...) A common example is: sound is eternal, since it is audible and audibility is pervaded by eternality (i.e. all that is audible is eternal, like sound-ness, the common property of all sound particulars); but sound is non-eternal, since it is originated (by clapping hands, etc.) and all that is originated is non-eternal, like a pot, etc. Critics from other philosophical schools have objected that counterinference is not an additional kind of pseudo-prover. Since it is impossible for an inferential subject both to have and not to have a probandum, either at least one of the inferential marks does not belong to the inferential subject (the fallacy of being unestablished) or at least one of the inferential marks lacks pervasion (the fallacy of deviation) and, accordingly, counterinference should be subsumed under those fallacies. Nyaaya philosophers have responded by pointing out that the formal structure of counterinference is different from that of the other fallacies: in counterinference we have two different inferential marks but not in the other candidates. The epistemic result of counterinference is also different from that of the other fallacies mentioned, it is argued further. Moreover, it is contended (against a Nyaaya faction) that the epistemic result is not doubt as specifically understood in Nyaaya but desire to know the truth about the chosen inferential mark and the probandum. Accordingly, counterinference may be explained as that which provides the ground for inquiring what is the truth about the original inferential mark and its probandum due to presentation of an inferential assimilation (paraamarsha) that contradicts the original inferential assimilation. The discussion yields also a broader normative principle that contradiction or counterproof provides the epistemic ground for further inquiry even if there is proof. The selection is from the Tattva-cintaa-maNi, the canonical Navya-Nyaaya work of GaMgesha (14th century CE?). The selection is from a large work and presupposes some things explained elsewhere in the text. Further, though written with great precision the work paradoxically belongs to the old Indian philosophical oral tradition in which a beginner is expected to read it with the help of additional information supplied by an expert. Hence paying close attention to what is implied in the context and supplementing certain ideas is necessary for interpretation and understanding. (shrink)

Indian logic is mainly devoted to the study of nyaya the logical structure of which is analogous to that of a categorical syllogism. In a nyaya it is inferred that since the probans (similar to the middle term) is pervaded by or never exists without the probandum (similar to the major term) and since the probans belongs to the inferential subject (similar to the minor term), the probandum belongs to the inferential subject. Many modern scholars hold that in early Indian (...) logic a nyaya was an analogical argument from particular to particular. We disagree. Early Nyaya works say explicitly that what deviates is a pseudo-probans; this implies that a probans is non-deviant or pervaded by the probandum and thus that a universal premise stating the pervasion of the probans by the probandum is needed. Such a universal premise is also found in articulated arguments. Further, a counterargument based on mere analogy to a nyaya based on a universal connection is viewed as a pseudo-refutation.

This paper deals with psycho-physical dualism as developed by Nyaya-Vaisesika philosophers. It is argued that internal states like pleasure, desire, etc. that are directly observable only by one’s own self and not by others and thus are private are not bodily states that are directly observable by one’s own self and others and thus are public. Common experiences such as I am happy, I want this, etc. testify, in the absence of compelling evidence to the contrary, that desire, etc. belong (...) to the self. The self is not only non-physical but also a permanent substance contrary to the Buddhist-Humean view that there are only fleeting internal states and no abiding self. Desire, etc. presuppose that the person who experienced something in the past remembers it now and desires it so that the agent of previous experience and later remembrance is the same continuant person.

In the Stoic view a definition is a representation of a peculiar characteristic that is neither too wide nor too narrow and has necessary or reciprocal force and is a statement of analysis matchingly expressed. That is, a peculiar characteristic is convertible and coextensive with the definiendum. Many scholars hold that for the Stoics a defining characteristic is not only a feature that is co-extensive with the definiendum but is also essential. We do not find any conclusive evidence for this (...) claim. The Stoics nowhere say that a defining feature is not only peculiar but also essential. They also sometimes offer more than one definition of a thing and this goes against the Aristotelian position that since a thing has single essence, there can only be one definition in the ideal sense. Further, the Platonic/Aristotelian tradition views a definition as being mainly concerned with relations between universals. But for the Stoics universals are mental constructs, individuals alone are real, and definitions are ultimately about individuals. (shrink)
