The source code is the best neighboring matching method, which will find out a best 16x16 macro block to conceal the lost macor block. this code is written by Matlab.

Predict a new frame from a previous frame and only code the prediction error • Prediction error will be coded using an image coding method (e.g., DCT-based as in JPEG) • Prediction errors have smaller energy than the original pixel

a) On sample artificial, 8X8 / 16X16 images, take the DFT, DCT, WT, & HT. Print the image & transform matrix side by side b) Repeat the above on real images of size 256X256, and display the transform coefficients as 8-bit intensity images along
