Human Body Attribute Recognition via Heat Map Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human body attribute recognition technologies often result in inaccurate results due to the misidentification of body features, such as the head being mistaken for the torso, leading to incorrect attribute recognition.
Innovation Solution
A method and apparatus that utilize a recognition model to generate heat maps, fuse global and local heat maps, and correct the focus area for each attribute, improving the accuracy of human body attribute recognition by ensuring each attribute focuses on the appropriate area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If recognition is performed on multiple human body features simultaneously, then comprehensive attribute recognition is achieved, but misidentification between connected body parts occurs
Solution Approach 1:
The patent divides the human body into multiple independent feature regions (head, torso, limbs) and processes each region separately through dedicated recognition branches. This segmentation prevents misidentification between connected body parts while maintaining comprehensive attribute recognition capability across all body regions.
Solution Approach 2:
The patent applies different recognition strategies and attention mechanisms to different body regions based on their specific characteristics. Each body part receives customized processing tailored to its local features, improving identification accuracy while maintaining overall system versatility.
2Adaptability or versatility
If the recognition model focuses on multiple attributes simultaneously, then comprehensive attribute recognition is achieved, but the focus area becomes diffuse and less accurate
Solution Approach 1:
The patent segments the recognition process into multiple independent branches, each dedicated to specific body regions or attribute types. This allows the model to maintain sharp focus on individual attributes while preserving the ability to recognize multiple attributes comprehensively through the integrated multi-branch architecture.
Solution Approach 2:
The patent introduces attention mechanisms and heat map visualization that add a spatial dimension to attribute recognition. By mapping attribute importance across different body regions, the model can simultaneously handle multiple attributes while maintaining precise focus through dimensional expansion of the recognition space.
