Abstract

The fundamental technique of vision-based multi-touch technique is the high performance image processing. In this paper, two algorithms are presented to resolve the problems of blob recognition and tracking. Image contour transformation algorithm is adopted to analyze the existence of finger contact area and Minimum Distance First (MDF) algorithm is designed to identify and track the corresponding blob in two sequential images. The result shows that the performance of two algorithms fully meets the requirement of real time multi-touch system.
