Image processing method and apparatus, and storage medium

Abstract

The embodiment of the invention discloses an image processing method and apparatus, and a storage medium. The method comprises the steps of obtaining a video file of a single-channel video stream, each frame of image in the video file being spliced by a colored image and a gray image corresponding to the colored image; performing decoding on the each frame of image in the video file to generate adata image corresponding to the each frame of image; performing segmentation on the data image to generate a colored image and a gray image corresponding to the each frame of image; performing synthesis on the colored image and the gray image to obtain a synthetic image corresponding to the each frame of image; and generating a target video file according to the synthetic image, and displaying thetarget video file. The effect that the processing only needs to be performed on the video file of the single-channel video stream is implemented, operations such as synchronous hardware decoding on atwo-channel video, copying an image from a GPU (Graphics Processing Unit) to a CPU (Central Processing Unit) to synthesize and the like are avoided, and the efficiency of a terminal to perform imageprocessing is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an image processing method, device and storage medium. Background technique [0002] With the continuous popularization of terminals and the rapid development of terminal technology, the applications provided by terminals are becoming more and more abundant. For example, live broadcast applications, users can interact with anchors face-to-face and instantly by opening live broadcast applications on terminals, and watch the anchors broadcast exciting programs in real time. Users can also give gifts to anchors according to their own preferences, and special effects of gifts will be displayed on the terminal. [0003] In the prior art, taking presenting gift special effects as an example, since gift special effects generally require a transparent channel, it is necessary to adopt a two-channel video solution, that is, one channel is used to transmit color images (als...

Problems solved by technology

[0004] In the two-way video processing scheme, hardware decoding of each frame of the two-way video needs to be synchronized, and it is difficult to achieve synchronization. For example, it needs to wait for a certain period of time to achieve synchronization, and the A Images and RGB images need to be copied from the GPU to the CPU for synthesis, which requires CPU overhead for image synthesis; in addition, the live broadcast application itself needs hardware decoding of one video live stream, and additionally requires hardware decoding of these two channels of video. There will be compatibility issues on the model, so the efficiency of terminal processing is very low
