If you intend to resize an image, simply use the Matlab Image Toolbox.

There is a function for this purpose called imresize

B = imresize(A, scale)

You could:

  • just downsample it, take every n-th pixel along each row and column in the original image and write it to a new image; choose n to suit your requirements;
  • replace every n*n array of pixels by some average of the pixel values in the array; lots of definitions of average to choose from; again, choose n to suit your requirements.
