I have to extract 30 random patches of size 32*32 from an image and then storing all that patches in a single matrix.

please help!

I have done this using for loop but that extracts patches sequentially not randomly.

I was looking if there is any direct function in matlab, which does nearly the same.

You could use the randi function to generate random centerpoints and expand those to full patches.
