This abstract first appeared for US patent application 17636074 titled 'FEATURE CONVERSION LEARNING DEVICE, AUTHENTICATION DEVICE, FEATURE CONVERSION LEARNING METHOD, AUTHENTICATION METHOD, AND RECORDING MEDIUM

==Simplified Explanation==

The abstract describes a device that learns a feature conversion method based on comparing features extracted from images.
* Acquires a high-resolution image and reduces it to a lower resolution image.
* Enlarges the lower resolution image back to the original resolution.
* Extracts features from the original and enlarged images.
* Converts one of the extracted features into a different feature.
* Learns a method for converting features based on comparing the original and converted features.


==Original Abstract Submitted==

A feature conversion learning device is configured to acquire a first image, reduce the first image to a second image having lower resolution than the first image, enlarge the second image to a third image having the same resolution as the first image, extract a first feature that is a feature of the first image and a second feature, convert the second feature into a third feature, and learn a feature conversion method based on a result of comparing the first feature with the third feature.
