  1. PSNR calculation between two image clips
  2. Comparison between two image clips
  3. Overlaying information on top of an image
  4. Checking motion between two consecutive frames

Data Overlay  

During the codec development, you may need to check some of block information, like block type, quant level, motion vectors etc, and need to display, or overlay those information on top of each block. For 1D information, each block can be marked as different colors depending on different values; for 2D information, a vector can be drawn inside the block.
