Abstract

The invention relates to a wavelet image de-noising method and a wavelet image de-noising device based on a genetic algorithm. The wavelet image de-noising method comprises the steps of: acquiring a to-be-processed image and an image de-noising model, wherein the image de-noising model is obtained by learning and training performed on noise images in a training set based on an improved wavelet threshold de-noising algorithm, and the improved wavelet threshold de-noising algorithm is obtained by determining a wavelet threshold through adoption of the genetic algorithm; and performing de-noisingprocessing on the to-be-processed image according to the image de-noising model. Through adoption of the wavelet image de-noising method of the invention, when the image de-noising model is obtained,the wavelet de-noising algorithm and the genetic algorithm are effectively combined to obtain the optimal wavelet threshold (wherein the wavelet threshold is the key of the wavelet threshold de-noising algorithm), thus a de-noising rate is greatly improved when the image de-noising model is used to perform de-noising on the to-be-processed image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a genetic algorithm-based wavelet image denoising method, device, computer equipment and computer-readable storage medium. Background technique [0002] Image information has become an important source of information and an important means for human beings to obtain information due to its advantages of large amount of information, fast transmission speed, and long distance. However, in reality, images often contain noise. Image noise is unnecessary or disturbing information generated in the process of image acquisition and transmission. For example, in the process of image acquisition, the performance of the imaging sensor is affected by the environmental conditions and its own quality, which will generate noise in the imaging process of the image; During the image transmission process, due to the interference of the transmission channel, noise will also be intro...
