Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/085023
Kind Code:
A1
Abstract:
An image processing device includes processing circuitry configured to receive information indicating a single image, calculate respective densities for each person detected in the single image, select a target person from one or more people detected in the single image, determine whether another person of the one or more people in the single image overlaps the target person, and in response to a determination that the another person overlaps the target person, calculate a density for the target person based on the overlap, and output crowd density information for at least part of the single image, wherein the crowd density information for the at least part of the single image corresponds to a density of one or more people throughout the at least part of the single image and is based on a combination of the calculated density of the one or more people in the at least part of the single image.
