1 -2 Feature-Based Image Mosaicing

We propose an automatic image mosaicing method that can construct a panoramic image from digital still images. Our method is fast and robust enough to process non-planar scenes with free camera motion. The method includes the following two techniques. First, we use a multi-resolution patch-based optical flow estimation for making feature correspondences to automatically obtain a homography. Second, we developed a technique to obtain a homography from only three points instead of four, in order to divide a scene into triangles. Experiments using real images confirm the effectiveness of our method.
