  It'd be great if you could post the solution to the problem. It'll definitely help others with similar problem.

  Uh well, it wasn't a problem. I just didn't had matlab installed, that's why I wanted someone to read those image in matlab and convert the image vectors to hex and give it to me, so I can port it in the algorithm I am trying to implement in Verilog.
  
  Below is the code (I've commented it) for doing so. I just downloaded a lite version for Matlab 2006 and it did my work.
  
  

  A = imread('lenna_noise.gif');  % Read image
  z = dec2hex(A); %Convert to hex
  fid = fopen('lenna_noise.txt','w'); 
  fprintf(fid, [repmat('%x ', 1, size(z,256)), '\n'], z'); %write to text file in 255 X 255 fashion.
  fclose(fid);

  My image is grayscale and not rgb. Besides, how will it convert the image into vectors?

  Why not? I am not interested in raw image. I just wanted matrix form of my image for further processing. I am not trying to do compressions or similar hence raw image is not required for me.
  
  I was actually designing a median filter with some new sort algorithm as presented one of the IEEE paper.

  open an image in Mspaint in windows then save in the format of 24bit format ,then it can be accessed by matrices format as rows and columns...in C language and other languages to operate in hex format also..
