Hi,
I am working with image registration. I have gray-scale images (CV_8UC1). I have done the registration part. Now I want to check the alignment accuracy. I want to convert the intensity range to [-127 to 128] from [0 to 255]. How can I do that? What I am doing is:
- subtract the aligned image from template
- divide the result by 2
- add 128 to result
Is this correct? Do I need to convert the images from 8U ?
Thanks
