Image mosaicking, feature extraction, direct methods, SURF, VORONOI, ZNCC

An improved method of image mosaic based on VORONOI regions and SURF algorithm is proposed here. In this method the control pints from two input images are extracted using SURF algorithm. VORONOI method is used to divide the images in different regions based on the control points. Then using ZNCC correlation VORONOI region matching is performed. Finally geometric transformation is calculated between the two images, for this the regions with highest correlation scores is selected and the input images are overlapped to get the desired mosaicked. To create a natural-looking mosaics, a quasi homography warp is applied, which balances the perspective distortion against projective distortion in nonoverlapping region
