Simple image stitching algorithm using SIFT, homography, KNN and Ransac in Python.
For full details and explanations, you're welcome to read
The project is to implement a featured based automatic image stitching algorithm. When we input two images with overlapped fields, we expect to obtain a wide seamless panorama.
We use scale invariant features transform(SIFT) to extract local features of the input images, K nearest neighbors algorithms to match these features and Random sample consensus(Ransac) to calculate the homograph matrix, which will be used for image warping. Finally we apply a weighted matrix as a mask for image blending.
