Description

This paper (and accompanying MATLAB source code) is a review of the block matching algorithms used for motion estimation in video compression. It implements and compares 7 different types of block matching algorithms that range from the very basic Exhaustive Search to the recent fast adaptive algorithms like Adaptive Rood Pattern Search. The algorithms that are evaluated in this paper are widely accepted by the video compressing community and have been used in implementing various standards, ranging from MPEG1 / H.261 to MPEG4 / H.263. The paper also presents a very brief introduction to the entire flow of video compression.

Very good work

Suggestion: Following plots would make the program more complete.
(1) plot of the average number of
searches required per macro block
(2) plot PSNR comparison

An excellent piece of work! I used your code for comparison during my development of an alternative ME algorithm, and found it highly helpfull.

Please avoid for loop in minCost.m and costFuncMAD.m. Very time-consuming.

dear sir/madam
it's a m.s. in electrical computer eng. which wants to detect any jam situation in a tunnel traffic by using matlab. i searched matlab image processing tool box to find any useful thing, but i didn't find anything.
would y ou please help me how to do it.
best regards

Some files are from 1994 and can largely be optimised. Moreover, the code does not work well in the static areas. Needs improvements.

18 Apr 2007 puja hait

i am unable to figure out why mincost has been assigned the particular value=65537.plz tell ma what is the reason behind this?

26 Apr 2007 ruchika lalit

i am unable to get the pixel value of whole the image my code is retriving only the pixel value of first pixel and i cannot make the macroblocks of the image because without that i wont be able to apply these codes. plz help

It's good, and gives me some idea for my project.
Thanks.

22 Jan 2008 sankari sivalanka

its very good . sir i request u to plz give code for video compression which is very help ful for my project

23 Jan 2008 kimstik kimstik

costFuncMAD speedup:
err = sum(sum(abs(currentBlk - refBlk)));

is equvivalent:

err = 0;
for i = 1:n
    for j = 1:n
        err = err + abs((currentBlk(i,j) - refBlk(i,j)));
    end
end

09 Feb 2008 suresh kumar

its very good.....and i tried for my sequence but its not working and can you give some tips please sir

12 Feb 2008 raghava k

sir..i have seen ur code..in that i did not understand 'caltrain'...wat is caltrain..? and can u provide me with the source code to implement winner update strategy? atleast guidance please.

31 Jan 2009 Dhruv Dave

hi...
this is really good work...
but i am not getting motion vector....
how to get motion vector in that program and display the image with motion vector...

PLZ help me

12 May 2009 Dr. Murtaza Khan

The program my give incorrect results. For example in TSS method motionEstTSS.m. The following function call will give wrong results:
 costs(2,2) = costFuncMAD(imgP(i:i+mbSize-1,j:j+mbSize-1), ...
                    imgI(i:i+mbSize-1,j:j+mbSize-1),mbSize);
Because for video data pixel values are of type integer (0-255) i.e. imgP and imgI of type uint8. Therefore, first use casting to double then call this method.

e.g. a correct and more readable code would be

 currentBlk=imgP(i:i+mbSize-1,j:j+mbSize-1);
 refBlk=imgI(refBlkVer:refBlkVer+mbSize-1, refBlkHor:refBlkHor+mbSize-1);
                    thisCost=costFuncMAD(double(currentBlk),double(refBlk), mbSize);
  costs(costRow, costCol ) = thisCost;
