Innovation Solution

An image recognition method that utilizes machine learning to analyze blur degree, local feature information, and global feature information to determine the authenticity of human faces, employing a multi-dimensional approach to improve efficiency and accuracy, and includes a system architecture with a terminal device and server for real-time identification and risk assessment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional image recognition methods are used, then the recognition process is simple, but the accuracy of distinguishing real and fake human faces is low

Engineering Contradiction:
Improveaccuracy of real or fake identificationVSAvoidcomplexity of recognition system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the image recognition process into multiple independent modules: blur degree detection module, local feature extraction module, global feature extraction module, and classification module. Each module processes specific aspects of the image independently, allowing the system to achieve high accuracy through comprehensive multi-dimensional analysis while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional single-dimension recognition to multi-dimensional analysis by incorporating blur degree information, local features, and global features as separate analytical dimensions. This multi-dimensional approach enables the system to distinguish real and fake faces more accurately by examining the image from multiple perspectives simultaneously.

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

2Measurement precision

If multi-dimensional feature analysis is performed, then the accuracy of detection improves, but the processing time increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary blur degree detection and local feature extraction before global feature analysis. By conducting preliminary assessments on simpler features first, the system can quickly eliminate obviously fake or real images, reducing the need for full multi-dimensional analysis on all images and thereby decreasing overall processing time while maintaining high detection accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a hierarchical analysis approach where not all feature dimensions are processed with equal depth for every image. Based on preliminary detection results, the system adjusts the level of analysis applied to each image, performing partial analysis on images that can be confidently classified and excessive (full) analysis only on ambiguous cases, optimizing the balance between accuracy and processing time.

Inventive Principle:
Principle #16Partial or excessive action
