Feature matching and segmentation in motion perception.
We examined the role of feature matching in motion perception. The stimulus sequence was constructed from a vertical, 1 cycle deg-1 sinusoidal grating divided into horizontal strips of equal height, where alternate strips moved leftward and rightward. The initial relative phase of adjacent strips was either 0 degree (aligned) or 90 degrees (non-aligned) and the motion was sampled at 90 degrees ...
متن کاملSurface segmentation mechanisms and motion perception.
Two studies are presented which explore how depth information is determined from conditions of transparency and whether this information combines with other depth information to determine the segmenting of motion information on the basis of likely surface boundaries. The first study explored how binocular disparity combines with monocular depth cues associated with transparency to determine whe...
متن کاملWeakly supervised motion segmentation with particle matching
Motion segmentation refers to the task of segmenting moving objects subject to their motion in order to distinguish and track them in a video. This is a challenging task in situationswhere different objects share similar movement patterns, or in cases where one object is occluded by others in part of the scene. In such cases, unsupervised motion segmentation fails and additional information is ...
متن کاملEnergy Feature Integration for Motion Segmentation
This chapter deals with the problem of segmentation of apparent-motion. Apparent-motion segmentation can be stated as the identification and classification of regions undergoing the same motion pattern along a video sequence. Motion segmentation has a great importance in robotic applications such as autonomous navigation and active vision. In autonomous navigation, motion segmentation is used i...
متن کاملCommon mechanisms in apparent motion perception and visual pattern matching.
Common mechanisms in apparent motion perception and visual pattern matching. Scandinavian Journal of Psychology, 50, 526-534.There are close functional similarities between apparent motion perception and visual pattern matching. In particular, striking functional similarities have been demonstrated between perception of rigid objects in apparent motion and purely mental transformations of visua...
