How does the visual system compute the global motion of an object from local views of its contours? Although this important problem in computational vision (also called the aperture problem) is key to understanding how biological systems work, there has been surprisingly little neurobiologically plausible work done on it. This book describes a neurally based model, implemented as a connectionist network, of how the aperture problem is solved. It provides a structural account of the model's performance on a number of tasks and demonstrates that the details of implementation influence the nature of the computation as well as predict perceptual effects that are unique to the model. The basic approach described can be extended to a number of different sensory computations.Sereno first reviews current research and theories about motion detection. She then considers the formal aspects of the aperture problem and describes a model of pattern motion perception that stands out in several respects. The model takes into account the structure of the visual system and attempts to build on known neurophysiological structures that might be available for solving the aperture problem, comparing performances in tasks involving direction and speed acuity, transparency, and motion coherency to human performance. The model's emphasis on the details of implementation rather-than on the goals of computation show that the details of data representation change the nature of the computation, producing predictions (including several illusions) that are unique and that can be confirmed through psychophysical experiments.Margaret Euphrasia Sereno is Assistant Professor of Psychology at the University of Oregon.

This is an important book, discussing a significant and very general problem in sensory processing. The model presented is simple, and it is elegant in that we can see, intuitively, exactly why and how it works. Simplicity, clarity, and elegance are virtues in any fields, but not often found in work in neural networks and snesory processing. The model described in Sereno's book is an exception. This book will have a sizeable impact on the field.
