ABSTRACT:
Edges/corners in an image can be detected and tracked over time by first sampling the image at periodic time intervals, and then processing the samples to obtain the intensity value for each pixel within each image acquired at a particular time. For each pixel, the bidirectional intraframe correlation of its intensity with the intensities of pixels along each of several directions within the same image is computed. Also, the bidirectional interframe correlation of the intensity of each pixel in each image with the intensities of pixels along each of several directions spanning several images is established. The intraframe and interframe intensity correlations are processed to obtain spatiotemporal tangent information about isobrightness surfaces and curves which are indicative of edges and corners, respectively, and their image motions.
