Utilization of Merge-Sorting Method to Improve Stitching Efficiency in Multi-Scene Image Stitching

Aiming at the problem of single stitching scenes (ordered or disordered images), which are time-consuming and involve complex computation during the image stitching, a multi-scene image stitching method based on merge sorting is proposed called merge-sorting image stitching (MSIS). We established an image stitching model based on merge sorting, directly stitching the matched images without traversing all the images and sorting them. Compared with the traditional method, this method significantly reduces the computational time taken matching irrelevant image pairs and improves the efficiency of image registration and stitching. The experimental results show that, compared with the binary tree-based model, our method reduces the time required to complete image stitching by about 10% and the distortion of the stitched images.
