Image analysis system and method for minimizing paralysis angle

摘要

A system and method of counting and analyzing each image of a plurality of features by minimizing the paralysis angle associated with each feature whose image is being analyzed by line-to-line scanning techniques is disclosed. The system and method involves the temporary storage of the X-coordinates of the boundary intercepts of each feature along one line scan and then selecting the last-to-occur of such intercepts to generate in memory a modified binary video signal to define the trailing edge of the feature. The modified video signal is stored one line scan and compared with the next real time line scan video signal in a manner such that the trailing edge data very accurately represents the actual position of the trailing edge of the feature.
