Title:
FILTER LEARNING DEVICE, FILTER LEARNING METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/161812
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a filter learning device capable of optimizing a recognition process that uses characteristics obtained from the properties of light. This filter learning device (10) comprises: an optical filter unit (11) that extracts a filter image from a learning image using a filter condition determined according to a filter parameter; a parameter updating unit (12) that updates the filter parameter using a result of executing an image analysis process related to the filter image; and a sensing unit (13) that performs sensing of an input image using a physical optical filter that satisfies a filter condition determined according to the updated filter parameter.
