Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If learning-based human body recognition is used, then recognition precision is improved, but data storage requirements and calculation complexity increase

Engineering Contradiction:
Improverecognition precisionVSAvoiddata storage requirements
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent segments the human body into multiple regions (head, torso, limbs) and processes each region separately using the learning-based recognition unit. This segmentation allows the system to focus computational resources on specific body parts rather than processing the entire image globally, reducing overall data storage and calculation requirements while maintaining high recognition precision for each body part.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension by dividing the image into multiple regions of interest and processing them in parallel. The learning-based recognition unit operates on segmented regional data rather than the complete image, effectively transforming a single high-dimensional processing task into multiple lower-dimensional tasks, thereby reducing data storage and computational complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If learning-based human body recognition is used, then recognition precision is improved, but calculation complexity increases

Engineering Contradiction:
Improverecognition precisionVSAvoidcalculation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the complex task of full-body recognition into simpler sub-tasks by segmenting the image into multiple body regions. Each region is processed independently by the learning-based recognition unit with simpler calculation requirements, reducing overall computational complexity while maintaining high precision through focused regional analysis.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by using the learning-based recognition unit only for specific body regions where high precision is most critical, rather than applying it uniformly across the entire image. This selective application reduces calculation complexity while maintaining recognition precision where it matters most.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If modeling-based human body recognition is used, then recognition speed is improved, but recognition precision decreases

Engineering Contradiction:
Improverecognition speedVSAvoidrecognition precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent merges two previously separate recognition systems into a hybrid architecture. The learning-based recognition unit provides high-precision detection for body regions, while the modeling-based recognition unit handles movement tracing and temporal consistency. This combination allows the system to achieve both high precision (from learning-based) and high speed (from modeling-based) simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller acts as an intermediary that coordinates between the learning-based recognition unit and the modeling-based recognition unit. It integrates the high-precision regional detection results with the high-speed movement tracing capabilities, mediating between the two systems to achieve both precision and speed in the overall recognition process.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An apparatus and a method for recognizing a human body in a hybrid manner are provided. The method includes calculating body information used for recognizing a human body from an input image, detecting a region of the human body in a learning-based human body recognition manner by using the calculated body information, and tracing a movement of the detected region of the human body in a modeling-based human body recognition manner. Thereby, it is possible to quickly perform more accurate and precise recognition of the human body.
