Abstract

Abstract A segment labeler/extractor outputs segments of video data stored in Random Access Memory for feature extraction and classification as targets. This function is accomplished by labeling the segments of a video frame as the segments are stored in a mass segment memory, sorting the mass segment memory to extract individual segment data, and storing this data in a segment memory where it can be accessed by an algorithm processor. Included in the subject invention is a segment labeler which consists of a segment label filter, adjacent label filter, memory, and sorter. The inputs to the segment labeler are a segment designator discrete which is set for only pixels which are in segments and a segment boundary designation discrete which is set for only pixels which are in segments and on the perimeter of the segment. The output of the segment labeler is a unique group of labels which define each segment. The groups of labels are then passed on to a control processor and handed to a segment extractor upon request. The segment extractor which consists of memory stores the segment intensity, position, status and label for all pixels in time sequence for a frame of data. Segments are then extracted individually by matching all pixels which belong to the unique group of labels. Individual segments are then presented for post processing, eliminating processing of any unnecessary data.
