Abstract:
An improved algorithm for image mosaic is proposed based on Harris corner detection.First,the improved algorithm changes the corner response function,calculates the similarity within 8 neighborhoods of the target pixel and makes non-maxima suppression within the circular region.Then,it makes a coarse matching for the detected Harris corner points by using the NCC algorithm.Then,it reduces the the false matched pairs by RANSAC algorithm.At last,the algorithm fuses the spliced images and eliminates the stitching gaps to complete image mosaic.Simulation results show that this improved algorithm increases the accuracy,stability and robustness of image mosaic.In a word,this improved algorithm can reach a target of seamless mosaic and has good practicability.
