Image Object Metadata Filtering for Bandwidth and Storage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metadata generated by cameras or devices along video data is complex and heavy, requiring significant bandwidth and storage, and often contains items not useful for subsequent analysis.
Innovation Solution
A method to manage metadata by determining the relevance of metadata items based on image data characteristics, such as resolution, detail, and compression, and discarding or reducing items that are not useful for subsequent analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all metadata items are retained for every detected object, then complete information is available for any potential analysis, but bandwidth and storage requirements become excessive
Solution Approach 1:
The patent extracts only the relevant metadata items needed for specific analysis types rather than retaining all metadata. By identifying which metadata are necessary for particular analysis purposes and extracting only those, the system reduces bandwidth and storage requirements while maintaining analysis completeness.
Solution Approach 2:
The patent applies different metadata retention strategies to different objects or regions based on their specific characteristics and analysis requirements. Rather than uniformly retaining all metadata across the entire image, the system selectively maintains metadata quality and quantity according to local needs.
2Adaptability or versatility
If comprehensive metadata is collected for all detected objects, then all potential analyses can be performed, but processing time increases
Solution Approach 1:
The patent performs preliminary classification of detected objects and pre-determination of which metadata items will be relevant for subsequent analysis. By making these decisions before actual analysis occurs, the system avoids processing unnecessary metadata during the analysis phase, thereby reducing processing time while maintaining analysis versatility.
3Quantity of substance
If metadata retention is reduced to save bandwidth and storage, then resource requirements decrease, but useful metadata may be discarded
Solution Approach 1:
The patent incorporates feedback mechanisms where the system evaluates the actual utility of retained metadata for analysis purposes. By monitoring whether retained metadata successfully supports analysis objectives, the system can adjust retention strategies to ensure useful metadata is preserved while unnecessary metadata is discarded.
Data Source
AI summary
A device and method for managing metadata associated with an object detected in an image, where the object corresponds to an area of the image are disclosed. A metadata item associated with the object is obtained, where the metadata item includes an identification of the area, and a quantitative level of an image data characteristic of the area or of the area as encoded is determined. A condition in relation to the determined quantitative level of the image data characteristic is evaluated, and on condition that the condition is fulfilled, reducing or discarding the metadata item. In an alternative, a level of compression of the area as encoded is determined, and it is determined if the level of compression is higher than a compression threshold. On condition that the level of compression is higher than the compression threshold, the metadata item is reduced or discarded.
