Embodiment Construction

[0061] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only Some, but not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] Existing image denoising methods mainly include: denoising methods based on prior models, denoising methods based on filtering, and filtering methods based on deep learning. Among the above three commonly used denoising methods, the denoising method based on the prior model cannot meet the real-time image processing requirements, and the processing efficiency is...

Abstract

The invention discloses an image fusion denoising method, a device and a system. The method comprises the steps: processing a noise image through a filtering algorithm to obtain a first denoised image, calculating the noise image and the first denoised image through a residual image method to obtain a first noise residual image; processing the noise image by using a first neural network model to obtain a second denoised image, and calculating the noise image and the second denoised image by using a residual image method to obtain a second noise residual image; and inputting the noise image, the first noise residual image and the second noise residual image into a second neural network model together for fusion and denoising to obtain a target denoised image. According to the invention, thenoise images processed by the collaborative filtering algorithm and the neural network model algorithm are combined together by adopting a fusion method, the target denoised image considering the denoising effect and image details is obtained, and the image denoising quality is better ensured.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image fusion denoising method, device and system. Background technique [0002] Image noise is a random change of brightness or color information in an image, and the more noise there is in the image, the worse the imaging quality of the image is. Image noise will not only affect the visual understanding of image clarity and accuracy, but more importantly, it will affect the quality of high-level image processing such as edge detection, image segmentation, and feature matching. Therefore, in order to meet the technical requirements of further image processing, a variety of image denoising methods have emerged in this field, such as: filter-based BM3D, deep learning-based DNCNN, prior model-based WNNM and other denoising methods. [0003] However, the above denoising methods have their own insurmountable defects: the filter-based denoising method is designed f...
