Document Type and Number:
WIPO Patent Application WO/2014/084218
Kind Code:
A1
Abstract:
The present invention relates to a subject detection device. A subject identification unit is an identifier in which a feature data group representing an image feature amount is the input and information indicating whether or not a subject (crossing pedestrian) is present is the output, the identifier being generated by machine learning. The identifier produces a feature data group from an image of at least one subregion (82) (non-masked region (102)) selected according to the type of subject from a plurality of subregions (82) constituting each of the learning sample images used for machine learning, and inputs the feature data group.
