Early Scene Analysis: Rapid Processing of Contours, Surfaces, and Objects in Human Vision.
Abstract
How does the human brain represent objects? How does it recognize them so rapidly? We have been able to show how 2-D information is built up from the parallel analysis of a set of visual attributes and how this information contacts memory in order to construct 3-D representations of the visual scene. We have demonstrated a simplified early contact with memory, occuring prior to any part-based or contour analysis an yet capable of guiding recognition. We have described a motion phenomenon which reveals the nature of image segmentation in a very direct manner. We have discovered a new technique to probe the dimensions of high-level shape recognition and we have described a new level of object description in terms of volumes which subsumes earlier work on contours and surfaces. Finally, work on shading and shadows is contributing to a new approach to rapid line labeling in images.
