Abstract

The invention relates to a dark light image denoising method based on dense connection convolution, and the method comprises the following steps: constructing a dense connection denoising convolutional neural network model, and carrying out the training of the dense connection denoising convolutional neural network model; acquiring a to-be-processed image, and preprocessing the to-be-processed image to obtain a target to-be-processed image; and processing the target to-be-processed image through the trained dense connection denoising convolutional neural network model to obtain a denoised image. According to the method, a large amount of image detail information can be retained even when an image in a dark light or backlight scene is processed, a high-quality denoised image is obtained, and a good denoising effect is achieved.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a method for denoising dark-light images based on densely connected convolution. Background technique [0002] Image noise refers to unnecessary or redundant interference information in image data. The existence of noise seriously affects the quality of the image, and noise reduction is particularly important. [0003] The existing image denoising methods generally use the local information of the image to smooth, or divide the image into blocks of a certain size, and combine two-dimensional image blocks with similar structures to form a three-dimensional image according to the similarity between image blocks. Arrays, and then use the method of joint filtering to process these three-dimensional arrays, and return the processed results to the original image through inverse transformation, so as to obtain a denoised image. [0004] However, these two image denoisi...
