Abstract

The present invention relates to an image splicing method and apparatus. The image splicing method includes: acquiring a first image and a second image, where an overlapping region exists between the first image and the second image; determining a to-be-processed region within the overlapping region, where a region within the overlapping region except the to-be-processed region is a remaining region; acquiring a luminance component or chrominance component of each pixel of the remaining region, and obtaining a weight value of each adjacent pixel pair of the remaining region; setting a weight value of an adjacent pixel pair within the to-be-processed region, where the weight value of the adjacent pixel pair of the to-be-processed region is greater than a weight value of an adjacent pixel pair of the remaining region; determining a splicing path having the least seam line intensity of all splicing paths within the overlapping region as an optimal seam line; and performing image splicing on the first image and the second image along the optimal seam line. According to the image splicing method and apparatus of the present invention, a seam line can be excluded from a to-be-processed region, so as to ensure that the to-be-processed region is spliced naturally and to improve subjective perception of a user in viewing an image.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image splicing method and device. Background technique [0002] Image mosaic technology includes two key links of image registration and image fusion. The goal of image registration is to find out the transformation relationship between two or more images with overlapping areas, establish a mathematical model of image coordinate transformation, and transform multiple images into a coordinate system by solving the parameters of the model. Image fusion technology is used to solve the problem of inaccurate registration caused by geometric correction, dynamic scenes or lighting changes, and merge adjacent images into one image. [0003] In the process of image fusion, the existing technology uses the best suture line technology to find an optimal suture line in the overlapping interval of multiple images, so that the energy difference between the two images on the suture l...
