Thanks for viewing this,

I am new to this forum as well as to image processing. I want to know what are the common region identification and matching methods.

It is not clear what you mean by "region identification". Please clarify.

In the meantime, review

Thanks for the reply, Actually I want to understand what are the methods used in image stitching, what are the methods used to identify common regions of two images in according to stitch them. I don't know to clarify further up to now what I understood is there are two methods named feature based and direct to identify common regions am I right? If so what are the algorithms/methods falls to two groups?

Thank you very much, your second research paper will be more useful. I did Google search but most of the research papers are not available for free. Please can I know, are there specific methods that are universally accepted, not only in the researches. I mean special algorithms, or basic concepts.

template matching such as normalized cross correlation is one
