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. A multi-frame image fusion method, which includes: a continuous image acquisition step to acquire multiple continuously captured images; a reference frame selection step to select a reference frame image from multiple continuously captured images, and the rest as auxiliary images; long-exposure image acquisition The step is to obtain a long exposure image through long exposure shooting; the registration step is to register the long exposure image and the auxiliary image with the reference frame image respectively; the region segmentation step is to perform region segmentation on the registered long exposure image, Segmentation into textured area and flat area; image fusion step, merging the registered auxiliary image and reference frame image according to the textured area and flat area to obtain a result image. By using this method, segmentation of image areas that may have smear and non-smear phenomenon for fusion is helpful to reasonably remove noise and smear phenomenon and obtain a high-definition image.

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...
