IMAGE SEARCH DEVICE AND TRAINING DATA EXTRACTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/171066
Kind Code:
A1
Abstract:
The present invention makes it possible to reduce the cost of collecting training data, and enable additional learning work to be simplified. A person detection unit (112) detects a person from an image, and a feature extraction unit (113) extracts a feature amount of the person and stores the feature amount in a feature amount database (130). An image search unit (115) searches for and stores an image in a search result database (150), and transmits the image to a terminal (320) as a search result. A classification item registration unit (117) acquires a classification item (applicable, non-applicable, etc.) assigned to an image that is a search result, and stores the classification item in the search result database (150). A training data extraction unit (118) extracts training data from the search result database (150) on the basis of a correlation between a feature amount and a classification item.
