Video Frame Target Object Superposition for Flexible Display Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display effect of image special effect functions in existing technologies is not flexible enough, limiting user creativity in image processing.
Innovation Solution
An image processing method and apparatus that acquires an original video, selects and separates video frame images containing a target object, performs transparentization processing on the object's image portion, and superposes it on another frame to create a special effect image, replacing the original frame to enhance flexibility in displaying the target object across different video frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional image special effect functions are used, then the processing is simple, but the display effect flexibility is insufficient
Solution Approach 1:
The patent segments the video processing into distinct modules: selecting a first video frame, selecting and separating a target object from a second video frame, performing transparentization processing, and superposing the transparentized object onto the first frame. This segmentation allows each module to be optimized independently while achieving flexible display effects.
Solution Approach 2:
The patent introduces temporal dimension by selecting frames from different time points in the video sequence. By extracting a target object from one frame and superposing it onto another frame from a different timestamp, the patent creates dynamic special effects that leverage the temporal dimension of video data.
2Adaptability or versatility
If video frames are processed to create special effects, then display flexibility is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-selecting and separating the target object from the video frame before the superposition step. The transparentization processing is also performed in advance, allowing the actual special effect composition to be executed efficiently when needed.
Solution Approach 2:
The patent extracts the target object from its original video frame context by separating it and creating a transparentized version. This extraction allows the object to be reused across different frames and backgrounds, reducing redundant processing and improving overall efficiency.

AI summary
The present disclosure discloses an image processing method and apparatus, an electronic device, and a computer-readable storage medium. The method therein includes: acquiring an original video; selecting, from the original video, a first video frame image; selecting, from the original video, a second video frame image in which a target object is contained, and separating, from the second video frame image, an image portion occupied by the target object in the second video frame image; performing transparentization processing on the image portion occupied by the target object in the second video frame image to obtain a transparentized image, and superposing the transparentized image on the first video frame image to obtain a special effect image; and replacing, in the original video, the second video frame image with the special effect image to form a target video.
