Regarding matrix similarity of image with rotation and scaling

I am having one image and i rotate that image at 30 degree angle and generated rotated image file. read they both and store it in matrix

I1=imread('binaryImage1.png');

I2=imread('rotate_30.png');

i want to do such operation so that i can conclude that this two images are same.

is there any image processing package which can help me?

here i consider only one rotation, it may have any degree rotation, partial cropping can be there.

please help me. i really need help. thank you in advance.

I can recommend to search in the net at first, if you have a question. Then you will find e.g.:

• https://stackoverflow.com/questions/24241278/image-object-orientation-and-rotation-using-matlab/24584922 (maybe a simple regionprops call is sufficient already?)
