Solution Overview
Problem
Current image processing systems struggle to accurately distinguish synthetic images from real ones, especially with the advancement of artificial intelligence and deep learning, posing challenges for authenticity verification in graphic design, news, and media industries.

A computer-implemented method using a test ensemble of discriminative tools, trained with Generative Adversarial Network (GAN) models, evaluates images to determine their synthetic score, reducing the need for exhaustive analysis and leveraging unsupervised learning to quickly assess the authenticity of images with high certainty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If exhaustive analysis methods are used to distinguish synthetic images from real ones, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The detection system is divided into multiple independent discriminative tools, each specialized in detecting specific artifacts or characteristics of synthetic images. These tools work in parallel to evaluate different aspects of an image (e.g., texture patterns, frequency domains, edge characteristics), allowing comprehensive analysis without requiring sequential exhaustive processing of the entire image.
Solution Approach 2:
The system employs a ensemble of discriminative tools where each tool performs a specialized partial analysis rather than requiring one comprehensive exhaustive analysis. By combining multiple partial evaluations (each focusing on specific synthetic image characteristics), the system achieves high detection precision while maintaining processing efficiency through targeted rather than exhaustive examination.
2Reliability
If multiple discriminative tools are combined in a test ensemble, then reliability is improved, but device complexity increases
Solution Approach 1:
Multiple independent discriminative tools are merged into a unified test ensemble that processes images collectively. Each tool contributes its specialized detection capability, and their results are combined through weighted aggregation to produce a final synthetic image assessment. This merging approach enhances reliability by leveraging diverse detection perspectives while managing complexity through a structured ensemble framework.
Solution Approach 2:
The test ensemble is designed as a universal detection system that can handle various types of synthetic images through multiple discriminative tools. Each tool in the ensemble serves multiple purposes by detecting different artifacts, and the ensemble as a whole provides universal applicability across diverse synthetic image generation methods, reducing the need for specialized systems for each synthetic image type.
3Manufacturing precision
If deep learning algorithms are used to generate synthetic images, then manufacturing precision is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The system converts the harmful effect of high-quality synthetic images (which are difficult to distinguish from real images) into a benefit by training discriminative tools to specifically recognize the subtle artifacts and characteristics introduced by deep learning algorithms. The very features that make synthetic images realistic also create detectable patterns that the ensemble of discriminative tools can identify, turning the challenge of high manufacturing precision into a detection opportunity.
Solution Approach 2:
The discriminative tools focus on detecting local quality characteristics and subtle artifacts in specific regions of images rather than requiring global analysis. By examining local patterns such as texture inconsistencies, frequency domain anomalies, and edge characteristics in different image regions, the system can identify synthetic images generated by deep learning algorithms without needing to analyze the entire image exhaustively, thus reducing detection difficulty while maintaining precision.
