Motion Perception and Mid-Level Vision
Note: the phenomena described in this chapter are very difficult to understand without viewing the moving stimuli. The reader is urged to view the demos when reading the chapter, at: 2 Like many aspects of vision, motion perception begins with a massive array of local measurements performed by neurons in area V1. Each receptive field covers a small piece of the visual world, and as a result suf...
متن کاملA conceptual framework of computations in mid-level vision
If a picture is worth a thousand words, as an English idiom goes, what should those words-or, rather, descriptors-capture? What format of image representation would be sufficiently rich if we were to reconstruct the essence of images from their descriptors? In this paper, we set out to develop a conceptual framework that would be: (i) biologically plausible in order to provide a better mechanis...
متن کاملBridging the Robot Perception Gap with Mid-Level Vision
The practical application of machine perception to support physical manipulation in unstructured environments remains a barrier to the development of intelligent robotic systems. Recently, great progress has been made by the large-scale machine perception community, but these methods have made few contributions to the applied robotic perception. This is in part because such large-scale systems ...
متن کاملMid-level vision and recognition of non-rigid objects
In this dissertation I address the problem of visual recognition of non rigid objects I introduce the frame alignment approach to recognition and illustrate it in two types of non rigid objects contour textures and elongated exible objects Frame alignment is based on matching stored models to images and has three stages rst a frame curve and a corresponding object are computed in the image Seco...
متن کاملLuminance and color inputs to mid-level and high-level vision.
We investigated the interdependence of activity within the luminance (L + M) and opponent chromatic (L - M and S - [L + M]) postreceptoral mechanisms in mid-level and high-level vision. Mid-level processes extract contours and perform figure-background organization whereas high-level processes depend on additional semantic input, such as object knowledge. We collected mid-level (good/poor conti...
