Abstract

The embodiment of the invention belongs to the technical field of computer graphics, and relates to an image noise reduction method and device, computer equipment and a medium thereof.The method comprises the steps that a rendering video stream is obtained, the rendering video stream comprises multiple frames of rendering images, and each frame of rendering image comprises multiple pieces of layer information; and performing noise reduction synthesis processing on each image layer information in each frame of rendered image to obtain a pre-noise-reduced rendered image, obtaining a target rendered image, an adjacent frame of rendered image of the target rendered image and a target object existing in the target rendered image and the adjacent frame of rendered image from the pre-noise-reduced rendered image, and according to the position of the target object, obtaining the target rendered image according to the position of the target object. According to the method, the color value of the pixel point of the target object in the target rendering image is adjusted according to the color value of the pixel point of the target object in the target rendering image so as to obtain the denoised target rendering image, on one hand, reduction of denoising errors of multiple frames of rendering images in the concentrated denoising process is facilitated, on the other hand, multiplexing of inter-frame information is achieved, and the denoising quality and denoising efficiency of the rendering images are improved.

Description

technical field [0001] The present application relates to the technical field of computer graphics, and in particular, to an image noise reduction method, apparatus, computer equipment and medium thereof. Background technique [0002] Rendering an image refers to rendering a scene image by adjusting parameters such as light, color, and angle, so that the generated scene image can vividly display the rendered design effect. In the graphics pipeline, rendering is the last important step, through which the final display effect of the 3D model and animation is obtained. [0003] With the rapid development of today's video rendering technology, high requirements are placed on rendering efficiency and effects. Usually, a single-frame image rendering is divided into scene rendering stage and post-processing stage. The scene rendering stage mainly obtains a rough rendering effect through the rendering calculation of a certain number of samples. This image usually contains a certai...
