Immersion Generation Using Foreground-Background Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies fail to effectively enhance immersion and stereoscopic effects across varying viewing angles due to limitations in image processing, particularly in separating foreground and background areas and controlling blur, leading to degraded image quality.
Innovation Solution
An apparatus and method that separate an input image into foreground and background areas using lightness information, classify edges, enhance detail in the foreground area, and adaptively perform blurring using a combination of local activity calculation, hue value differences, and gain control to increase the stereoscopic effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the entire image is processed with high detail enhancement, then the foreground area quality is improved, but the processing complexity and time increase significantly
Solution Approach 1:
The image is segmented into foreground and background areas based on depth information, allowing different processing strategies to be applied to each region. The foreground area receives detailed enhancement while the background area receives simplified processing, resolving the contradiction between quality and complexity.
Solution Approach 2:
Different quality levels are applied to different regions of the image. The foreground area maintains high detail and sharpness, while the background area is processed with lower computational complexity operations, achieving overall quality improvement without proportional complexity increase.
2Manufacturing precision
If the background area is processed with high detail enhancement, then the overall image quality is improved, but the stereoscopic effect and immersion are reduced
Solution Approach 1:
The image is divided into foreground and background regions, enabling selective processing where the background receives appropriate quality enhancement without excessive detail that would reduce the perceived depth and stereoscopic effect.
Solution Approach 2:
Different processing parameters are applied to foreground and background areas. The background area uses adjusted parameters that maintain acceptable quality while preserving the depth cues necessary for stereoscopic effect and immersion.
3Productivity
If the foreground area is separated and processed separately, then the detail enhancement efficiency is improved, but the separation accuracy requirement increases
Solution Approach 1:
Depth information is obtained in advance through depth maps or stereo matching before the actual image processing. This preliminary separation based on depth data enables efficient subsequent processing while the accuracy requirements are managed through robust depth estimation techniques.
4Adaptability or versatility
If blurring is applied to the background area, then the stereoscopic effect is enhanced, but the background detail quality deteriorates
Solution Approach 1:
Different quality levels are intentionally applied to different regions. The background area receives controlled blurring to enhance depth perception and stereoscopic effect, while the foreground maintains full detail. This local differentiation resolves the contradiction by making the quality reduction acceptable in the context of overall immersive experience.
