I have two sets of face images - RGB images, acquired from web-camera and Thermal images, collected using Optris PI450.
I want to find the temperature of face regions like nose, forehead, chin, etc. using the combination of visible and thermal images. For instance, I want to detect nose in visible images, and find corresponding pixel location in thermal images.
To start with, I did stereo calibration using a heated checkerboard, and found both camera's intrinsic and extrinsic parameters using MATLAB Stereo Calibration toolbox.
Any suggestion on how to proceed further will be grateful.

Dear Namrata,
co-registration of multi-modal images is a field of research that was extensively researched 20-15 years ago in the medical imaging domain, were the co-registration of functional imaging to anatomical imaging (e.g. PET-scan images to MRI or CT images or fMRI images to MRI or CT or ultrassound images to CT) is of capital importance for functional studies or for radiotherapy planning. There exists a lot of well-studied and validated methods that are, for example, nowadays integrated into commercial radiotherapy software.
Your images are NOT a stereo pair, this is not a path I would suggest. The methods you employed seem to me to be very inadequate for that co-registration task you have at hand.
So, besides trying the relatively new methods suggested by Tahmina and Somnath (I am not familiar to them), I suggest that you take a serious look at medical imaging literature from the period of 20-10 years ago. Below I suggest a few surveys:

Thank you for all the suggestions. I decided to use homography matrix for my problem.
