Title:
STATE DETERMINATION DEVICE AND STATE DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/124791
Kind Code:
A1
Abstract:
The present invention improves accuracy in determining the state of a subject in an image with a background captured therein. An image reconfiguration unit 1 reconfigures a captured image and outputs the reconfigured image. A mask generation unit 2 uses the reconfigured image as an input, separates a subject and the background in the captured image, and outputs a generated mask indicating a subject region in the captured image. A color determination unit 3A determines the state of the color of the subject on the basis of a comparison result between pixel values of the captured image and the reconfigured image. A shape determination unit 4 determines the state of the shape of the subject on the basis of the generated mask outputted by the mask generation unit 2 and a template mask relating to the shape of the subject in a normal state. A integrated determination unit 5 uses a color determination result outputted by the color determination unit 3A and a shape determination result outputted by the shape determination unit 4, and outputs an integrated determination result obtained through integration of said results.
