Object Metadata Grouping for Lower Video Data Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video distribution systems generate excessive metadata by individually storing and transmitting position information for detected objects, leading to increased data volume.
Innovation Solution
An information generation apparatus determines whether to group objects based on positional relationships, integrating them into a single object and generating metadata for the integrated object, thereby reducing the amount of information transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position information regarding each detected object is individually stored and transmitted in metadata, then object identification accuracy is maintained, but the amount of metadata increases
Solution Approach 1:
The patent merges multiple detected objects into a single integrated object when they satisfy specific conditions (spatial proximity, temporal continuity, semantic relationship). Instead of transmitting separate metadata for each object, the system transmits a single metadata entry representing the integrated object, thereby reducing metadata volume while preserving necessary identification information through the integration concept
Solution Approach 2:
The patent segments the metadata generation process into two paths: individual object metadata generation and integrated object metadata generation. The determination unit evaluates whether to apply integration based on object relationships, allowing selective application of the merging principle only when beneficial, thus maintaining accuracy for objects that should remain separate while reducing volume for objects that can be integrated

AI summary
An information generation apparatus includes a determination unit configured to determine, based on a predetermined condition, whether to enable a grouping process for grouping objects detected from an image, and a generation unit configured to generate metadata regarding the objects detected from the image, wherein, in a case where the determination unit determines that the grouping process is to be enabled, the determination unit determines a plurality of objects as grouping targets according to positional relationships between the objects detected from the image, and wherein the generation unit generates metadata including information regarding an integrated object obtained by integrating the plurality of objects determined as the grouping targets.
