Abstract

This paper proposes a new moving-objects tracking method processed by a local spiral labeling with CAM (Content Addressable Memory). The local spiral labeling method was proposed in order to improve one of the shortcomings of TV telephones. The conventional labeling, however, needs huge processing time and a memory capacity in order to compute connecting relations between label numbers. CAM has some functions to search and write the plural contents of the memory at the same time. CAM is suitable for a real time labeling. This paper shows a new labeling algorithm called local spiral labeling, a real-time labeling scheme utilizing CAM, and a prototype system of human head tracking using 0.5 micrometers BiCMOS gate-array technology.
