Abstract

The embodiment of the present invention discloses a video de-noising processing method. The method comprises: obtaining the current frame image of the video; when there is an object frame image, performing pixel value difference calculation of the pixel point of the current frame image and the pixel point of the corresponding position in the object frame image, and obtaining the absolute value of the pixel value difference, wherein the object frame image is the frame image outputted after the last one image of the current frame image is subjected to de-noising processing; determining whether the absolute value is larger than a presetting threshold value or not; if it is determined that the absolute value is larger than a presetting threshold value, updating the pixel point of the corresponding position in the objet frame image to the pixel point in the current frame image; and when the current frame image completes the difference calculation of the presetting number of pixel points, outputting the updated object frame image. The present invention further discloses a video de-noising processing device. According to the invention, the technical problem is solved that the video de-noising algorithm cannot satisfy the requirements of low real-time video flow calculation amount and having no delay of a mobile terminal in the prior art.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a video noise reduction processing method and a video noise reduction processing device. Background technique [0002] With the advent of the information age, self-media came into being. Every user can become a disseminator of information, and people can transmit information to information receivers through various forms of communication, among which, the forms of communication include text communication, image communication, audio communication, video communication, etc. With the rapid development of Internet technology, users are more and more inclined to choose the way of real-time live broadcast of online video, share some anecdotes with others or perform live personal talent shows, people can use personal computers or mobile terminals to conduct live video (or video calls) . [0003] In mobile live broadcast and mobile video call scenarios, due to the cross-lighting capabil...
