Combining Object and Feature Dynamics in Probabilistic Tracking
(2005-03-02)Objects can exhibit different dynamics at different scales, a property that isoftenexploited by visual tracking algorithms. A local dynamicmodel is typically used to extract image features that are then used as inputsto a ...

Feature Extraction Without Edge Detection
(1993-09-01)Information representation is a critical issue in machine vision. The representation strategy in the primitive stages of a vision system has enormous implications for the performance in subsequent stages. Existing ...

Finding Junctions Using the Image Gradient
(1991-12-01)Junctions are the intersection points of three or more intensity surfaces in an image. An analysis of zero crossings and the gradient near junctions demonstrates that gradient-based edge detection schemes fragment edges ...
