Abstract

The invention relates to an image fusion method, comprising the following steps: acquiring multiple images with different exposure degrees; converting each image into a YUV color space, and extracting a Y component; calculating each image according to the Y component quantify and evaluate the edge features to obtain initial fusion weights; generate a grayscale co-occurrence matrix according to the Y component of each of the images, and calculate the value of each Y component in the grayscale co-occurrence matrix probability density function; the saliency factor of each image is calculated according to the probability density function; the initial fusion weight is optimized according to the salience factor to obtain the optimal fusion weight; according to the optimal fusion weight The fusion weight fuses a plurality of the images to obtain a target image. In the technical solution of the present invention, the saliency factor is used to optimize the initial fusion weight, so that the image can retain more texture details and control the noise better.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image fusion method based on a wide dynamic algorithm and an image fusion system. Background technique [0002] The current WDR algorithm is mainly divided into two directions, one is the intra-frame WDR of a single image, and the other is the WDR using image fusion. The intra-frame WDR algorithm mainly uses methods such as contrast enhancement or histogram stretching to achieve WDR. This method is simple and easy to implement, but the effect is poor, and contrast enhancement may introduce other problems such as noise; while image fusion Effective information areas in different exposure images can be extracted to obtain wide dynamic images, and the actual effect will be better. [0003] The multi-exposure image fusion algorithm uses multiple images with different exposures to fuse their respective effective information to obtain a normal exposure image. The key to t...
