---------------------------------------

ProbX_Y.m: used to solve problem X.Y


Motion_Estimation_2D.m: estimate block wise motion vectors between two video frames using exhaustive search block matching algorithm. The search accuracy can be integer or half pel. This function calls EBMA.m() to compute the motion vector for a given block. 

EBMA.m: estimate the motion vector for a given block

InterMotion.m: first estimate block motion vectors using EBMA, and then interpolate the block motion vectors to obtain a dense motion field.

Prob6_12.m,Prob6_13.m,Prob6_15.m call the  function Motion_Estimation_2D.m()

Prob6_14 call the function  InterMotion.m


Note that because fread() reads in data from a binary file into an image matrix column wise, whereas the sample image files (foremanX.Y) are written in a binary file row wise, the actual image width is considered ImgHeight, and actual image height ImgWidth.


foremanX.m: sample video frames from the sequence foreman (CIF format, 352x288 per frame, Y only)

slena.bmp, flowers.tif: sample images used by programs.
