Biocybernetics Of Vision: Integrative Mechanisms And Cognitive Processes


Book Description

Visual cognition is an important area of biocybernetics. It ranges from the filtering processes of early vision to the structural and functional organization of the visual centres, as well as, in higher animals, to the neuronal plasticity, the decision-making rules, the effect of noise, the role of attention, the ambiguity of patterns, and the time dimension. All these factors contribute to the cognitive interpretation of visual sensation that takes place in visual perception. A side field is machine vision, in which the signal processing known from animal vision is applied to the mobile robots responding to light stimulation.




Biocybernetics of Vision


Book Description




Vision


Book Description

The light sense is conceivably the key sense in both the animal and the plant kingdom. Vision research, undoubtedly a fast-growing field, is providing impressive results OCo thanks to modern theoretical and methodological advances. The approach of biophysics and neuroscience seems to be of great benefit and, for this reason, the present book gives an outline of recent acquisitions and updated advanced methods concerning this approach. Visual mechanisms and processes are analysed at several (molecular, cellular, integrative, computational and cognitive) levels by different methodologies (from molecular biology to computation) applied to different living models (from protists to humans, via invertebrates and lower vertebrates). Contents: The Optics of Animal Eyes (M F Land); Rhodopsin-Like Proteins: The Universal and Probably Unique Proteins for Vision (P Gualtieri); The Molecular Design of a Visual Cascade: Molecular Stages of Phototransduction in Drosophila (R Paulsen et al.); Molecular Changes During Primary Visual Pathway Development (K L Moya et al.); Color Vision and Retinal Randomness of the Japanese Yellow Swallowtail Butterfly, Papilio Xuthus (K Arikawa et al.); Patch-Clamping Solitary Visual Cells to Understand the Cellular Mechanisms of Invertebrate Phototransduction (C Musio); Phototransduction in Retinal Rods and Cones (Y Koutalos et al.); Formation of OC ONOCO and OC OFFOCO Ganglion Cell Mosaics (L M Chalupa); Endogenous Nitric Oxide Modulates Signal Transmission from Photoreceptors to On-Center Bipolar Cells in the Rabbit Retina (B Lei & I Perlman); Now You See It, Now You Don't: Shunting Inhibition in Early Vision (L Borg-Graham et al.); Visual Perceptual Learning (N Berardi & A Fiorentini); Functions of the Primate Temporal Lobe Cortical Visual Areas in Invariant Visual Object and Face Recognition (E T Rolls); Vector Code in Neuronal Networks (E N Sokolov); and other papers.

Vision: Images, Signals And Neural Networks - Models Of Neural Processing In Visual Perception


Book Description

At the fascinating frontiers of neurobiology, mathematics and psychophysics, this book addresses the problem of human and computer vision on the basis of cognitive modeling. After recalling the physics of light and its transformation through media and optics, Hérault presents the principles of the primate's visual system in terms of anatomy and functionality. Then, the neuronal circuitry of the retina is analyzed in terms of spatio-temporal filtering. This basic model is extended to the concept of neuromorphic circuits for motion processing and to the processing of color in the retina. For more in-depth studies, the adaptive non-linear properties of the photoreceptors and of ganglion cells are addressed, exhibiting all the power of the retinal pre-processing of images as a system of information cleaning suitable for further cortical processing. As a target of retinal information, the primary visual area is presented as a bank of filters able to extract valuable descriptors of images, suitable for categorization and recognition and also for local information extraction such as saliency and perspective. All along the book, many comparisons between the models and human perception are discussed as well as detailed applications to computer vision./a

Drosophila Eye Development


Book Description

1 Kevin Moses It is now 25 years since the study of the development of the compound eye in Drosophila really began with a classic paper (Ready et al. 1976). In 1864, August Weismann published a monograph on the development of Diptera and included some beautiful drawings of the developing imaginal discs (Weismann 1864). One of these is the first description of the third instar eye disc in which Weismann drew a vertical line separating a posterior domain that included a regular pattern of clustered cells from an anterior domain without such a pattern. Weismann suggested that these clusters were the precursors of the adult ommatidia and that the line marks the anterior edge of the eye. In his first suggestion he was absolutely correct - in his second he was wrong. The vertical line shown was not the anterior edge of the eye, but the anterior edge of a moving wave of patterning and cell type specification that 112 years later (1976) Ready, Hansen and Benzer would name the "morphogenetic furrow". While it is too late to hear from August Weismann, it is a particular pleasure to be able to include a chapter in this Volume from the first author of that 1976 paper: Don Ready! These past 25 years have seen an astonishing explosion in the study of the fly eye (see Fig.
