Problems solved by technology

[0003] However, in the actual multi-frame shooting scene, when multiple frames are fused, there will be light or heavy motion blur. During the process, there will be more serious smear phenomenon, which seriously affects the quality of image denoising imaging; in scenes with large noise, many noises will also be misdetected as motion status, which will affect image denoising

Abstract

The invention relates to the technical field of image processing, and provides a multi-frame image fusion method and device. The multi-frame image fusion method comprises the following steps: a continuous image acquisition step: acquiring a plurality of continuously shot images; a reference frame selection step: selecting one reference frame image from the plurality of continuously shot images, and taking the rest as auxiliary images; a long exposure image obtaining step: obtaining a long exposure image through long exposure shooting; a registration step: respectively registering the long exposure image and the auxiliary image with the reference frame image; a region segmentation step: carrying out region segmentation on the registered long exposure image, and segmenting the long exposureimage into a texture region and a flat region; and an image fusion step: fusing the registered auxiliary images and the reference frame images according to the texture area and the flat area to obtaina result image. By using the infrared and visible light image fusion method, the image regions which may have the streaking phenomenon and do not have the streaking phenomenon are segmented and fused, so that the noise and the streaking phenomenon can be reasonably removed, and an image with high definition can be obtained.

Description

technical field [0001] The present invention generally relates to the technical field of image processing, and in particular relates to a multi-frame image fusion method and device. Background technique [0002] The multi-frame image fusion algorithm has been widely used in the industry because of its better denoising effect and better detail texture preservation than that of a single frame. Based on the consideration of memory and algorithm running time, the currently commonly used solution is: the camera continuously shoots 5-10 images, selects one of them as a reference frame, performs image registration on other images, and performs multi-frame image fusion on the registered images. Then a denoised image is obtained. [0003] However, in the actual multi-frame shooting scene, when multiple frames are fused, there will be light or heavy motion blur. During the process, there will be relatively serious smear phenomenon, which seriously affects the quality of image denois...
