A Robust Blob Recognition and Tracking Method in Vision-Based Multi-touch Technique


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… (More)
