If I understand correctly we first need to do a 'direct matching' i.e. find some couple of matching keypoints (SIFT descriptors having lowest Euclidean distance, e.g. using the technique proposed by D.Lowe, which is to say we have a match if no other candidate keypoint has a lower or equal Euclidean distance as the best … simpsons date of birth

"WebJul 12, 2024 · To estimate the homography in OpenCV is a simple task. It’s one line of code: H, __ = cv2.findHomography (srcPoints, dstPoints, cv2.RANSAC, 5 ) Before starting the coding stitching algorithm, we need to swap image inputs. So “img_” will take the right image, and “IMG” will take the left image. So let’s jump into stitching coding: " - Sift ransac python
