I want to be able to crop and rotate an area of interest from an image bounded by a rotated rectangle. The code I am using is the one posted under "Face Detection and Tracking Using the KLT Algorithm". I tried using imcrop but it only allows to use straight rectangles.

MATLAB can only represent rectangular numeric matrices, so it is not possible to crop a rotated rectangle to its rotated edges. You can only crop it to its bounding box. You can set everything outside the area of interest to a value that your code knows to ignore, such as 0 or (if you are using floating point) NaN
