How to register two gray scale similar images

Dear all,

I have two microscopic images, image-A which is a histological brain section image of rat-A, and image-B which is also a histological brain section of rat-B.

Both images are gray scale images and similar to each other but with slightly differences in size, orientation, and gray intensity information.

Is there someway to register these two images based on their gray scale intensity information or any other way (without using any manual landmark points)?

Thank you very much.

Did you look at the imregister() function in the Image Processing Toolbox?

YES, this is exactly what I want. I didn't know about this new function. Thank you very much.
