You can use the imresize function to scale the image up or down.

a = rand(3281,3164);
b = imresize(a,0.91024);

I think it works for these dimension .What If i have some other dimensions, how to get the value for resizing?

maybe interp2?

Im resize support both scale factor and absolute size.

a = rand(3281,3164);
b = imresize(a,[2987 2880]);
