blobpropagation

Tool: MATLAB 2015b

  • Convert videos to mp4 format as MATLAB might not be able to read avi files.
  1. training_limit: Finds the video specific skin color limits. a. Skin_training (using model limits) b. Facedetection

  2. blobdetection: Detect skin using the new limits. You need to determine the appropriate limits for R and B channels empirically for every video. For example, c1=mean(1)-3.5*sigma(1) (line 11). You may have to use values other than 3.5.

  3. tracking: Implements blob propagation a. Creates a priority matrix b. Calcopticalflow: calculates optical flow of top frame using Farneback c. Forward/ Backward propagation: Propagate blobs to next and previous frames
