Title:
CBD-NET-BASED MEDICAL ENDOSCOPIC IMAGE DENOISING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/022494
Kind Code:
A1
Abstract:
Disclosed is a CBD-Net-based medical endoscopic image denoising method. The method comprises: constructing and improving a CBD-Net to obtain a medical endoscopic image denoising model; obtaining a noise source according to an imaging principle of an endoscope; acquiring a simulated training set and a real training set, and acquiring a supplementary training set according to a noise generation source; training the medical endoscopic image denoising model by using the simulated training set, the real training set and the supplementary training set; and denoising a medical endoscopic image by using the trained medical endoscopic image denoising model. In the present invention, an endoscopic image is processed without changing factors such as an original tone and the brightness thereof; and by means of the present invention, medical image details are better retained.
