Abstract

The invention provides an image denoising method, electronic equipment and a storage medium. The method comprises the steps of: obtaining a plurality of initial image sequences; obtaining a signal-to-noise ratio among all the initial image sequences; and based on the signal-to-noise ratio, performing denoising processing on the initial image sequences to obtain a target denoised image sequence. According to the method, the noise level of the initial image sequences can be reduced, and meanwhile, the scanning content of each finally obtained target de-noised image sequence meets the consistency requirement.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to an image denoising method, electronic equipment and a storage medium. Background technique [0002] Image denoising has been widely used in natural image and video processing. Traditional denoising methods include spatial filtering, transform domain filtering, partial differential equations, variational methods, morphological noise filtering, etc. In addition, deep learning methods are used to image and Video denoising methods are also emerging in an endless stream, and they show better results than traditional methods. However, in order to obtain a better denoising effect, the deep learning method usually requires a large number of noise-free images as supervisory information to train the model, which is difficult for medical perfusion images. Most of the methods based on traditional methods for denoising medical images are applied to a single image sequence, s...
