Abstract

Image mosaicing is the act of combining two or more images and is used in many applications in computer vision, image processing, and computer graphics. It aims to combine images such that no obstructive boundaries exist around overlapped regions and to create a mosaic image that exhibits as little distortion as possible from the original images. Most of the existing algorithms are the computationally complex and don’t show good results always in obtaining of the stitched images, which are different: scale, light, various free points of view and others. In this paper we consider an algorithm which allows increasing the speed of processing in the case of stitching high-resolution images. We reduced the computational complexity used an edge image analysis and saliency map on high-detailisation areas. On detected areas are determined angles of rotation, scaling factors, the coefficients of the color correction and transformation matrix. We define key points using SURF detector and ignore false correspondences based on correlation analysis. The proposed algorithm allows to combine images from free points of view with the different color balances, time shutter and scale. We perform a comparative study and show that statistically, the new algorithm deliver good quality results compared to existing algorithms.
