Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] figure 1 It is a schematic diagram of an application environment of an image filtering method and device in an embodiment. Such as figure 1 As shown, the application environment includes a terminal 110 and a server 120 . The terminal 110 includes multiple terminals, and the terminal 110 performs network communication with the server 120 . After the video call connection is established between the two terminals 110, the image filtering device on the terminal 110 performs real-time filtering processing on the collected images, and sends the filtered images to the video terminal 110 for disp...

Abstract

The invention relates to an image filtering method and device. The image filtering method comprises the following steps: acquiring a frame of image; acquiring test pixel points from the frame of image; calculating a pixel difference between each test pixel point and an adjacent pixel point respectively; acquiring weights of the adjacent pixel points and the test pixel points according to the pixel differences; updating pixel values of the corresponding test pixel points according to the weights and the corresponding pixel values of two pixel points. The image filtering method and device can rapidly filter the acquired each frame of image based on a relationship between respective adjacent pixel points, can efficiently filter video images in real time, does not need to detect edge pixel points, and can retain strong edges, reasonably smoothen and smoothly transit weak edges, and gradually filter and flatten the pixel points through the differences.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image filtering method and device. Background technique [0002] With the development of computer technology and network technology, users are no longer satisfied with the naturally captured images, and usually need to process the captured images to make the people or objects in the images more delicate and the outlines clearer. Although traditional image processing software has a variety of special effects and filters based on people or objects, most of the filter special effects still stay on the solidified filter special effects. The video image changes, and the solidified filter processing effect is the same, rarely. Real-time preview and real-time sending of video images can be achieved, so that the video images seen by the other party and the local end are consistent. Therefore, traditional image processing methods cannot achieve video image filtering. Contents of the i...
