|Title of the thesis:||Hand Tracking|
|Summary:||This master thesis deals with hand tracking, which could be used as an input device for human computer interaction. After analyzing several approaches, we focus on the Flocks of Features algorithm. This algorithm takes into consideration skin color cue and feature motion detection. Features are being tracked on gray-level image using Lucas-Kanade tracker. To obtain the hand location, flocking behavioral model of birds is applied on these features. The algorithm is vulnerable to the corners and edges occurring in the background. We proposed the modification of this algorithm not to use the gray-level image as the input, but a processed image of the skin color probability map. This map does not contain the majority of the disturbing elements. To increase the invariance to the luminance conditions an adaptive histogram was introduced. We also proposed several initialization algorithms for multiple object tracking. In the conclusion the achieved results and possible future work are presented.|
