How do I rotate each block of image to be perpendicular to x-axis?

For each block of a fingerprint image, the local orientation is measured. I tried to rotate gradients by their mean orientation but it looks same as gradients and not perpendicular to x-axis.

You could use imrotate() on the block, or use various combinations of transpose (the ' operator), flipud(), and fliplr().
