Image multi-exposure fusion enhancement method and device, electronic equipment and storage medium

Abstract

The application provides an image multi-exposure fusion enhancement method and device, electronic equipment and storage medium, and relates to the technical field of image processing. The method comprises the following steps: acquiring a multi-exposure image sequence to be processed, and converting each exposure image into a luminance component and a chrominance component; calculating the exposure sensitivity of each pixel position in the luminance component according to a sensitivity weight factor; obtaining a smoothed attention weight according to the exposure sensitivity; constructing a multi-scale Laplacian pyramid corresponding to the luminance component, and constructing a corresponding Gaussian pyramid according to the smoothed attention weight; performing weighted fusion on the pyramids layer by layer to obtain a fusion pyramid coefficient, and obtaining a fusion luminance component through reconstruction, and performing structure fidelity processing on the chrominance component to obtain a fusion chrominance component; and obtaining an enhanced image according to the fusion luminance component and the fusion chrominance component. The application can cover various dynamic scenes and effectively improve the image fusion enhancement effect.
