Reconstruction of images from an in vivo multi-camera capsule with two-stage confidence matching

摘要

A method and apparatus of image stitching using confidence level of image matching on image pair to be stitched are disclosed. According to the present invention, the first quality of image matching is determined for a current image based on feature matching on first image pairs corresponding to the current image and a neighboring image set. If the first quality of image matching for at least one first image pair satisfies a first quality criterion, then the second quality of image matching is determined based on pixel-domain matching for one or more candidate image pairs, where each candidate image pair has a corresponding first quality of image matching satisfying the first quality criterion. If the second quality of image matching for a candidate image pair satisfies a second quality criterion, then the matched image pair is stitched.
