This article presents a novel full-reference image quality assessment algorithm by depicting the sub-band characteristics in the wavelet domain. The proposed image quality assessment method is based on energy estimation in the wavelet-transformed image. Image QA is achieved by applying a multilevel wavelet decomposition on both the original and the enhanced image. Next, the wavelet energy and vector are computed to obtain the percentage of the energy that corresponds to the approximation and the details, respectively. Further, the approximate and detailed (...) energy levels of both the original and the enhanced images are compared to formulate an image quality assessment. Numerous experiments are conducted on a dozen of image enhancement algorithms. The results presented show that the image with poor contrast in the foreground than the background has continuous regular coefficient values. The probability density function for such an image has a relatively lower WE and skewness compared with the background. The proposed scheme not only evaluates the global information of an image but also estimates the fine, detailed changes in an enhanced image. Thus, the proposed metric serves as an objective and effective FR criterion for color image QA. The experimental results presented confirm that the proposed WE metric is an efficient and useful metric for evaluating the quality of the color image enhancement. (shrink)

. Textline segmentation in handwritten documents is of real challenge and interesting in the field of document image processing. In this paper, we propose a handwritten textline segmentation scheme based on the concept of linked list. The proposed method consists of three stages, namely, preprocessing, linked list and mathematical morphology. The concept of the linked list approach is used to build a textline sequence and mathematical morphology is used to obtain the line separator. We experimentally evaluated our proposed method on (...) a document containing handwritten Kannada script. The results are compared with recent methods and show encouraging results. (shrink)

Automatic moving object detection and tracking is very important task in video surveillance applications. In the present work the well known background subtraction model and use of Gaussian Mixture Models have been used to implement a robust automated single object tracking system. In this implementation, background subtraction on subtracting consecutive frame-by-frame basis for moving object detection is done. Once the object has been detected it is tracked by employing an efficient GMM technique. After successful completion of tracking, moving object recognition (...) of those objects using well known Principal Component Analysis, which is used for extracting features and Manhattan based distance metric is used for subsequent classification purpose. The system is capable of handling entry and exit of an object. Such a tracking system is cost effective and can be used as an automated video conferencing system and also has applications like human tracking, vehicles monitoring, and event recognition for video surveillance. The proposed algorithm was tested on standard database on complex environments and the results were satisfactory. (shrink)

'This book is a masterpiece of theoretical thought. It anticipates the actual achievements of much of what we now call sociolinguistics.

Although research into the biosemiotic mechanisms underlying the purposeful behavior of brainless living systems is extensive, researchers have not adequately described biosemiosis among neurons. As the conscious use of signs is well-covered by the various fields of semiotics, we focus on subconscious sign action. Subconscious semiotic habits, both functional and dysfunctional, may be created and reinforced in the brain not necessarily in a logical manner and not necessarily through repeated reinforcement. We review literature that suggests hypnosis may be effective in (...) changing subconscious dysfunctional habits, and we offer a biosemiotic framework for understanding these results. If it has been difficult to evaluate any psychological approach, including hypnosis, this may be because contemporary neuroscience lacks a theory of the sign. We argue that understanding the fluid nature of representation in biological organisms is prerequisite to understanding the nature of the subconscious and may lead to more effective of treatments for dysfunctional habits developed through personal experience or culture.

The current status of explanation worked out by Physics for the Periodic Law is considered from philosophical and methodological points of view. The principle gnosiological role of approximations and models in providing interpretation for complicated systems is emphasized. The achievements, deficiencies and perspectives of the existing quantum mechanical interpretation of the Periodic Table are discussed. The mainstream ab initio theory is based on analysis of selfconsistent one-electron effective potential. Alternative approaches employing symmetry considerations and applying group theory usually require some (...) empirical information. The approximate dynamic symmetry of one-electron potential casts light on the secondary periodicity phenomenon. The periodicity patterns found in various multiparticle systems (atoms in special situations, atomic nuclei, clusters, particles in the traps, etc) comprise a field for comparative study of the Periodic Laws found in nature.

The association of Berdiaev's name with the phenomenon of perestroika seems strange at first glance and even illogical. But perestroika, which is proceeding—or, more precisely, is trying to proceed—under the sign of an intellectual renaissance, has naturally aroused interest in the names of Russian philosophers who have undeservedly been forgotten. One of these is N.A. Berdiaev . He was a Russian patriot and was profoundly concerned with Russia's fate. Living in a critical period, Berdiaev reflected a great deal over the (...) past, present, and future of his Motherland, advanced the idea of its transformation, and even used the term "perestroika" in doing so. His thoughts concerning Russia's political renewal are profound, and some of them are applicable to the present life of our society. (shrink)

The article analyzes the creativity of one of the most famous Russian neokantians Boris V. Yakovenko. Despite the fact that the work of Yakovenko becomes the subject of analysis of an increasing number of researchers both in Russia and abroad, it has not yet taken place in a systematic analysis. The article attempts to consider the philosophical creativity of the Russian philosopher systematically, revealing both the main directions of European thought that had the greatest influence on the position of Yakovenko (...) and the main areas of philosophy to which the efforts of the national thinker were directed. These, according to the author, include the history of philosophy and the system of so-called transcendental pluralism. It is pointed out that the history of philosophy for Yakovenko is a single holistic process and therefore is the history of the development of philosophical ideas, and not the history of life and work of individual philosophers. According to Yakovenko, the general philosophical scheme of historical development looks like this: from Greek cosmism to German epistemology and the beginning ontological turn in modern philosophy. There is also the belief of B.V. Yakovenko that there is no national philosophy. In his opinion, philosophy, as well as science in General, can only be international. His second main thesis concerning the development of philosophy is that philosophy should be independent from other branches of human knowledge and knowledge. She must not be a servant of theology or science. The article also presents various stages of the Russian philosopher's development of his version of the concept of pluralistic philosophy. According to Yakovenko, only pluralistic philosophy is able to know the essence as the main object of philosophy. (shrink)

Biological mimicry is regarded by many as a textbook illustration of Darwin’s idea of evolution by random mutation followed by differential selection of reproductively fit specimens, resulting in gradual phenotypic change in a population. In this paper, I argue that some cases of so-called mimicry are probably merely look-a-likes and do not gain an advantage due to their similarity in appearance to something else. In cases where a similar appearance does provide a benefit, I argue that it is possible that (...) these forms of mimicry were created in a single generation. An interpretive response to an appearance as a sign can make a new structure perform drastically differently in an environment. In such cases, Darwin’s natural selection mechanism only helps to explain gradual the spread of these new forms, not the creation of them. I argue that biosemiosis should be regarded as a much more powerful mechanism for affecting evolutionary trajectories than the gradualist view allows. I focus on two cases of butterfly mimicry: the Viceroy (Nymphalidae: Limenitis archippus) and Monarch (Nymphalidae: Danaus plexippus) butterflies, supposed Müllerian mimics, and deadleaf mimic butterflies (Kallima).

The philosophy of religion as presented by Hermann Cohen and Paul Natorp, the founders and main representatives of the Marburg School of Neo-Kantianism, is an important and at the same time controversial part of their philosophical systems. The discussion around the problems of religion began within the Marburg School and still continues among those who study that School. The reason for this is that “fitting” philosophical thinking about the phenomenon of religion into the classical triad of any system of philosophy, (...) i. e. effectively formulating that phenomenon in logical concepts, ethical postulates and aesthetic principles touched the very foundations of that system. Drawing mainly on the rough notes and correspondence of Cohen and Natorp I argue that, in spite of internal and quite important differences over the problems of religion and its place in philosophical constructions, Cohen and Natorp, first, retained their commitment to critical idealism and remained loyal to their philosophical school to the end and, second, followed the principle of mutual respect, preserving their professional and human sympathy for each other. Besides, I substantiate my assertion that Marburg Neo-Kantians had different concepts of the special place of religion in the system of philosophy. The specific nature of this difference warrants the discussion not only of the boundary of reason and rationality but adds new dimensions to that boundary, filling it with content and thus broadening the very sphere of critical idealism. In the course of the discussion of the problems of religion, Paul Natorp and Hermann Cohen stake a claim to projects for the serious transformation of philosophy which they tried to implement in their later works.
