Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video applications fail to meet increasing user requirements for adding texture effects to video scenes, resulting in a lack of interestingness in shared videos.
Innovation Solution
A video processing method that involves acquiring three-dimensional reconstruction data and a texture image, determining target brightness based on a mapping relationship, adjusting brightness, and mapping the texture image onto the video using three-dimensional reconstruction data to create a target video image with flowing and flickering texture effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real scene video is shared on a video consumption platform, then video sharing functionality is achieved, but video interestingness is insufficient
Solution Approach 1:
The patent performs preliminary actions by pre-obtaining mapping relationships between pixel positions and initial brightness/brightness change rates, and pre-processing texture images with brightness adjustment before mapping them onto the video. This prepares the video data in advance with texture information and brightness characteristics, so that during video playback or sharing, the interestingness effect can be directly applied without complex real-time processing, thus resolving the contradiction between video interestingness and processing complexity
Solution Approach 2:
The patent creates a copy of the original video by mapping a texture image onto the video frame. This texture copy contains additional visual information and brightness characteristics that enhance the video's interestingness. The texture image is mapped to corresponding pixel positions on the video frame, creating a composite video output that combines original video content with enhanced texture effects, thereby improving video interestingness without requiring complete re-shooting or complex scene modification
2Adaptability or versatility
If texture effects are added to video scenes, then video interestingness is improved, but processing complexity increases
Solution Approach 1:
The patent applies local quality by adjusting brightness characteristics at different pixel positions on the texture image according to pre-obtained mapping relationships. Each pixel position has its own initial brightness and brightness change rate, allowing different regions of the texture to have different brightness properties. This localized brightness adjustment creates more realistic and interesting texture effects while using efficient per-pixel processing rather than complex global processing
Solution Approach 2:
The patent changes parameters by adjusting the brightness of pixels on the texture image according to pre-obtained mapping relationships that define initial brightness and brightness change rates. This parameter adjustment transforms the texture image to have dynamic brightness characteristics that enhance video interestingness. The parameter changes are applied systematically through mapping relationships, avoiding the need for complex real-time parameter optimization during video processing
