Abstract

The invention relates to an endoscope image noise reduction method and device, an electronic device and a storage medium, and the method comprises the steps: carrying out the multi-scale geometric transformation of a target region in a Laplacian image of an endoscope image, and obtaining a low-frequency coefficient of the target region; performing enhancement calculation on the low-frequency coefficient according to the enhancement coefficient to obtain a corrected low-frequency coefficient; performing inverse transformation of multi-scale geometric transformation on the pixel value of the target pixel according to the corrected low-frequency coefficient to obtain a denoised target pixel; and obtaining a denoised Laplacian image according to the denoised target pixel, and fusing the denoised Laplacian image with a corresponding Gaussian image to obtain a denoised endoscope image. According to the method and the device, the problem that the edge information in the endoscope image is lost by adopting a noise reduction method of a common camera image in the related technology is solved, the information of the edge area of the endoscope image is reserved, and the image loss is reduced.

Description

technical field [0001] The present application relates to the technical field of endoscopes, and in particular to an endoscope image noise reduction method, device, electronic device and storage medium. Background technique [0002] Endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software and other technologies. Specifically, the endoscope includes image sensors, optical lenses, light source lighting, mechanical devices, etc. It can enter the stomach through the oral cavity or enter the body through other natural channels, and can see lesions that cannot be displayed by X-rays. Images acquired through an endoscope generally need to be denoised before being analyzed. [0003] The endoscopic image noise reduction method in the related art generally follows the noise reduction algorithm of ordinary camera images, such as the noise reduction method in the space domain, the noise reduction ...
