Abstract:
1. A method for optical object tracking, the method comprising: using an optical flow tracker (OFT) to detect data associated with an object within a first frame of image data and to calculate a first estimated image location of the object based on the data detected using the OFT; using a decision forest tracker (DFT) to detect data associated with the object within the first frame of image data and to calculate a second estimated image location of the object based on the data detected using the DFT; determining a final image location based on a synthesis of the first estimated image location and the second estimated image location; tracking the object using the final image location; and based on the final image location, updating a learning library in a first phase and a second phase subsequent to the first phase, wherein the first phase comprises providing false positive window information based on the data detected using the DFT to the learning library.
