Video image data encoding and compression system using edge detection and luminance profile matching

摘要

An image processing system which processes image data on a line by line basis. Edges in the images are detected as discontinuities in intensity. The intensity profile between detected edges is determined and matched to a polynomial function. Data representing the detected edges and data relating to the detected profile are stored as a data set for further processing. The data set for one image may be compared to that for another similar image in order to match features between images and thereby produce three-dimensional information about a scene.
