How can I select the specific area between two pictures using feature detection?

Hi All,
please understand my bad English:)
I attached two images as the reference and object image. these images were captured by two cameras at the same time, so each scene has a little bit different perspective view. I am able to make two images with on overlap using image registration. However, the current functions for detecting matching points(detectMinEigenFeatures, detectSURFFeatures, detectMSERFeatures and so on) are work automatically. I want to restrict the detecting area manually(rectangle area is fine). In other words, I want to get a result of matching points within selected specific area only.
I found "Pick Control Point Pairs Manually", but I have to select exact same pixel per each image in this method.
Thanks,

your comment was very useful to me!! I wanted to detect matching points between two images within the specific area only. I solved my problem using imcrop+correlation+feature detection. Thanks a lot!

I agree with KSSV, the simplest way to perform this operation would be to crop your images (using 'imcrop') to the desired detection area and detect matching points along the cropped image.

Thanks for your comment. I solved my problem using "imcrop".
