Video Frame Smoothing for Scene Transition Visual Jump Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing technologies often result in visual jumps during scene transitions due to frame picture adjustments, leading to a poor playback experience.
Innovation Solution
A video processing method that performs scene classification identification and smoothing on video frames near scene switching positions, using a smoothing process based on the classification results to ensure natural transitions and avoid visual jumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If frame picture adjustment (image enhancement) is performed on video frames according to video scene, then image quality is improved, but visual jump occurs at scene transformation position
Solution Approach 1:
The patent applies preliminary action by performing scene classification identification on video frames before executing frame picture adjustment. The system identifies scene transformation positions in advance and marks them, then uses this information to guide subsequent processing. Specifically, frames at scene transformation positions are processed differently (with reduced adjustment intensity or different adjustment parameters) to prevent visual jumps while maintaining image quality improvement in stable scenes.
2Object-affected harmful factors
If scene classification identification is performed on video frame sequence, then visual jump is prevented, but processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the video frame sequence processing into distinct stages: scene classification identification, scene transformation detection, frame marking, and conditional picture adjustment. The scene classification module segments frames into different scene types, and the system segments processing intensity based on whether frames are at scene transformation positions. This modular approach manages complexity by handling different frame types through separate processing paths.
Solution Approach 2:
The patent applies local quality by applying different processing strategies to different portions of the video sequence. Frames at scene transformation positions receive different adjustment parameters or reduced adjustment intensity compared to frames in stable scenes. The system locally adapts the picture adjustment strength based on the specific frame's position and scene context, rather than applying uniform processing across all frames.

AI summary
A video processing method and apparatus, a computing device and a computer readable storage medium are disclosed. The video processing method includes obtaining a video frame sequence comprised in a video to be processed, performing scene classification identification on the video frame sequence so as to obtain a scene classification identification result of the video frame sequence, and performing a smoothing process to the video frame sequence based on the scene classification identification result.
