Automatic image mosaic system using steerable Harris corner detector

Image mosaic is to be combine several views of a scene in to single wide angle view. This paper proposes the image mosaic based on feature based approach. The steps in image mosaic include feature point detection, feature point descriptor extraction and feature point matching. A RANSAC algorithm is applied to eliminate number of mismatches and obtain transformation matrix between the images. The input image is transformed with the correct mapping model for image stitching and same is estimated. In this paper, feature points are detected using steerable Harris and compared with traditional Harris, SUSAN corner detectors.
