摘要： Systems and methods for tracking human hands using parts based template matching are described. One embodiment of the invention includes a processor, a reference camera and memory containing: a hand tracking application; and a finger template including an edge features template. In addition, the hand tracking application configures the processor to: detect at least one candidate finger in a frame of video data received from the reference camera, where each candidate finger is a grouping of pixels identified by searching the frame of video data for a grouping of pixels that have image gradient orientations that match the edge features of the finger template accounting for rotation and scaling differences; and verify the correct detection of a candidate finger by confirming that the colors of the pixels within the grouping of pixels identified as a candidate finger satisfy a skin color criterion.

摘要： Systems and methods for tracking human hands by performing parts based template matching using images captured from multiple viewpoints are described. One embodiment of the invention includes a processor, a reference camera, an alternate view camera, and memory containing: a hand tracking application; and a plurality of edge feature templates that are rotated and scaled versions of a finger template that includes an edge features template. In addition, the hand tracking application configures the processor to: detect at least one candidate finger in a reference frame, where each candidate finger is a grouping of pixels identified by searching the reference frame for a grouping of pixels that have image gradient orientations that match one of the plurality of edge feature templates; and verify the correct detection of a candidate finger in the reference frame by locating a grouping of pixels in an alternate view frame that correspond to the candidate finger.
