Detection of the movements of persons from a sparse sequence of TV images

摘要

This paper describes a method for detecting persons walking in a passageway from two consecutive TV images at long intervals. The method consists of the following steps: (1) extracting candidate areas for persons from TV images by image processing; (2) detecting persons in the areas on the basis of their shapes and sizes, and locating them in a passageway; (3) finding the correspondence of persons between two images on the basis of their locations. Special hardware called DIP was employed for high speed image processing.
