Perceptual Spatial Content Compositing With Selective Metadata Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content creation and presentation technologies lack efficient methods for compositing and rendering metadata to adjust the appearance of content based on spatial and temporal metadata, leading to suboptimal display quality and resource inefficiency.
Innovation Solution
A method for generating metadata that includes spatial and image metadata for content elements, allowing for perceptually meaningful compositing and rendering, which involves determining the types of content, generating metadata using APIs, and modifying content elements based on spatial and temporal data to improve display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If metadata is generated for each individual frame sequentially, then the processing is simple and straightforward, but the overall productivity is low and resource efficiency is poor
Solution Approach 1:
The system performs preliminary analysis of multiple frames to identify common spatial relationships and metadata patterns before final compositing. By pre-processing frame data to extract spatial metadata, luminance information, and composition rules in advance, the system reduces the computational burden during actual compositing operations, thereby improving overall productivity while maintaining processing quality
Solution Approach 2:
The patent combines multiple frames into a single composited display unit, allowing metadata to be generated and applied across the entire composite rather than processing each frame separately. This merging approach enables shared metadata processing for common elements across frames, significantly improving efficiency while maintaining the ability to handle frame-specific variations
2Productivity
If content elements are composited without spatial and temporal metadata, then the compositing process is faster and simpler, but the display quality and perceptual accuracy deteriorate
Solution Approach 1:
The system applies different levels of metadata processing to different content elements based on their spatial relationships and importance. Critical elements with significant spatial or temporal relationships receive detailed metadata processing, while less critical elements use simplified processing. This selective approach maintains high display quality for important content while improving overall compositing efficiency
Solution Approach 2:
The patent implements partial metadata processing by generating complete spatial and temporal metadata only when necessary for achieving desired display quality, rather than processing all possible metadata for all elements. This partial action approach balances compositing speed with display quality by applying metadata processing selectively based on content requirements
3Manufacturing precision
If spatial and temporal metadata are processed for all content elements, then the display quality improves, but the device complexity and computational resources required increase
Solution Approach 1:
The system segments the metadata processing task into distinct modules: spatial relationship analysis, temporal change detection, luminance comparison, and compositing rule application. Each module handles a specific aspect of metadata processing independently, reducing overall system complexity while enabling comprehensive processing. This segmentation allows parallel processing and makes the complex system more manageable and maintainable
4Use of energy by moving object
If frames are displayed sequentially without compositing, then the processing resources are reduced, but the ability to create integrated content presentations is limited
Solution Approach 1:
The patent adds a spatial composition dimension to traditional sequential frame processing by compositing multiple frames into a single integrated display unit. This dimensional transformation allows content elements from different frames to coexist and interact in the same spatial space, enabling new presentation capabilities while managing resource usage through efficient metadata processing and selective compositing operations
Data Source
AI summary
Approaches for generating metadata for content to be composited and rendered using the generated metadata are described. These approaches can be used with the development and distribution of one or more web pages or other graphical user interfaces. For example, one can collect content (e.g., images, animation, text and user interface elements) to be composited together into a web page and invoke a set of APIs to generate the metadata for the content of the web page that will be composited; a metadata generation system receives the calls through the API and generates the metadata. The web page can then be distributed with the generated metadata which can be used to create the display of the web page with content that is perceptually modified based on the metadata about the individual elements on the web page and their spatial proximity.
