This code has been developed and tested with Windows 7, Matlab R2012b (64-bit). To compute the optical flow, users need to make sure that OpenCV 2.4.10 is installed.

Users can directly run "benchmark_function.m" to test the code. In addition, we set the default path for the video sequences in "D:\data_seq", users can edit "benchmark\configSeqs.m" to revise the path and choose the videos that you want to test.

We write this code without optimization, and several modifications can be added to the code to make it run faster, e.g., we can parallelize the code in the feature extraction and model updating process, which will greatly saves the computation time.
