Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating works of art, particularly paintings, are inefficient and lack accuracy in determining the actual artist based on visual features.
Innovation Solution
A computing device utilizing machine learning and artificial intelligence to analyze image data of test paintings and compare them with known works by a specific artist and other artists, employing image tiles, numerical descriptors, and classifiers to determine the likelihood of authorship.

1Productivity
If manual comparison of features is used for art authentication, then the method is simple to implement, but the process is time-consuming and subjective
Solution Approach 1:
The patent replaces manual mechanical comparison of artistic features with an automated machine learning system. The system uses neural networks to automatically analyze and compare features of paintings, substituting the human expert's visual inspection process with computational algorithms that can process images and make authentication decisions without human intervention.
Solution Approach 2:
The patent creates digital copies of paintings in the form of image data files and divides them into tiles. These digital representations are then fed into the machine learning model for analysis. The system works with copies of the original artworks rather than the physical pieces themselves, enabling automated processing while preserving the essential visual features needed for authentication.
2Measurement precision
If machine learning classification is used for art authentication, then objectivity and accuracy improve, but the computational complexity increases
Solution Approach 1:
The patent divides the painting images into smaller tiles that are processed independently by the machine learning model. This segmentation allows the system to handle large images by breaking them down into manageable units, reducing the computational burden on the neural network while maintaining comprehensive analysis of the entire artwork through aggregation of tile results.
Solution Approach 2:
The system analyzes only the visual features and stylistic characteristics that are most relevant for authentication, rather than processing every possible aspect of the painting. The machine learning model focuses on extracting and comparing specific features such as brushstroke patterns, color usage, and compositional elements that are indicative of an artist's style, thereby reducing unnecessary computational complexity.
3Reliability
If feature comparison with known artworks is used, then authentication reliability improves, but the time required for analysis increases
Solution Approach 1:
The patent pre-processes and stores feature data from known authentic artworks and their corresponding style characteristics in a database before authentication is needed. This preliminary preparation allows the machine learning model to quickly compare test paintings against the stored reference data without requiring time-consuming real-time analysis of artistic styles and techniques during the actual authentication process.

AI summary
A computing device to authenticate works of art comprises a processor programmed to receive test image data corresponding to an image of a test painting to be authenticated; receive a plurality of first artist image data files; receive a plurality of multiple artist image data files; generate a plurality of test painting tiles from the test image data file; generate a plurality of groups of first artist painting tiles; generate a plurality of groups of multiple artist painting tiles; train a classifier to determine one of a plurality of classes for each first artist painting tile and each multiple artist painting tile; use the trained classifier to determine the class for each test painting tile; and determine whether the test painting was likely painted by the first artist according to a percentage of the test painting tiles determined to be the class corresponding to the first artist.
