How can the RANSAC algorithm be utilized to estimate a homography matrix for robustly matching corresponding points in two images?
The RANSAC algorithm can be used to estimate a homography matrix by iteratively selecting random sets of corresponding points in two images and calculating the homography matrix for each set. The set with the most inliers (points that fit well with the estimated homography) is then chosen as the best estimate. This helps in robustly matching corresponding points between the two images.

Apply SIFT and RANSAC on matrix[10X10]. Compare the results?
OpenCV has the function cv::findHomography which can optionally use RANSAC to find the homography matrix relating two images. You can see an example of this function in action here. Specifically the section of code you are interested in is: FlannBasedMatcher matcher; std::vector< DMatch > matches; matcher.match( descriptors_object, descriptors_scene, matches ); for( int i = 0; i < good_matches.size(); i++ ) { //-- Get the keypoints from the good matches obj.push_back( keypoints_object[ good_matches[i].queryIdx ].pt ); scene.push_back( keypoints_scene[ good_matches[i].trainIdx ].pt ); } Mat H = findHomography( obj, scene, CV_RANSAC ); You can then use the function cv::perspectiveTransform to warp the images according to the homography matrix. Other options for cv::findHomography other than CV_RANSAC are 0 which uses every point and CV_LMEDS which uses the Least-Median method. More info can be found in the OpenCV camera calibration documentation here.
