Solution Overview

Problem

In behavior detection systems, uniformly set parameters can lead to reduced accuracy due to varying physical characteristics among subjects, and manually setting parameters for each type of behavior is cumbersome and prone to errors.

Innovation Solution

An information processing apparatus that sets behavior detection parameters based on input information related to subject characteristics in an image, allowing for optimized detection of behaviors by adjusting parameters for each subject's unique characteristics.

1Ease of operation

If behavior detection parameters are uniformly set for all subjects, then the system operation is simplified, but the detection accuracy is reduced due to varying physical characteristics among subjects

Engineering Contradiction:

Improvesystem operationVSAvoiddetection accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system automatically detects subject characteristics (height, physique) from input information and self-adjusts the behavior detection parameters accordingly, eliminating the need for manual parameter setting by operators while maintaining high detection accuracy for each individual subject

Inventive Principle:

Solution Approach 2:

The system dynamically changes behavior detection parameters based on detected subject characteristics, adjusting parameters such as threshold values and detection ranges to match each subject's physical attributes, thereby resolving the contradiction between uniform operation and accurate detection

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If behavior detection parameters are manually set for each subject, then the detection accuracy is improved, but the system complexity and time consumption increase

Engineering Contradiction:
