Camera Motion Determination from Dynamic Perceptual Grouping of Line Segments
We present here a discussion on the use of perceptual grouping to improve structure and egomotion recovery algorithms for monocular cameras. In particular we look at grouping lines to avoid the need for trinocular algorithms. We also present a number of methods for grouping lines, including a novel method that infers planar groups from those demonstrating a linear deformation. Computer vision i...
متن کاملEffects of similarity on apparent motion and perceptual grouping.
Effects of similarity in colour, luminance, size, and shape on apparent motion and perceptual grouping were examined in part 1 in two parallel experiments on the same seven subjects. In both experiments, the effect of similarity was compared with that of proximity in competitive, bistable stimulus situations. A combination of a larger horizontal separation between the homogeneous stimulus eleme...
متن کاملPerceptual Grouping of Biological Motion Promotes Binocular Rivalry
Investigation of perceptual rivalry between conflicting stimuli presented one to each eye can further understanding of the neural underpinnings of conscious visual perception. During rivalry, visual awareness fluctuates between perceptions of the two stimuli. Here, we demonstrate that high-level perceptual grouping can promote rivalry between stimulus pairs that would otherwise be perceived as ...

متن کاملPerceptual Grouping and Change Detection Perceptual Grouping in Change Detection Perceptual Grouping and Change Detection
Detection of an item changing its location from one instance to another is typically unaffected by changes in the shape or color of contextual items. However, we demonstrate here that such location change detection is severely impaired if the elongated axes of contextual items change orientation, even though individual locations remain constant and even though the orientation was irrelevant to ...
