Object detection apparatus and control method thereof, and storage medium

摘要

The object detection apparatus prevents or eliminates detection errors caused by changes of an object which frequently appears in a background. To this end, an object detection apparatus includes a detection unit which detects an object region by comparing an input video from a video input device and a background model, a selection unit which selects a region of a background object originally included in a video, a generation unit which generates background object feature information based on features included in the background object region, and a determination unit which determines whether or not the object region detected from the input video is a background object using the background object feature information.

1. An object detection apparatus comprising:
a video input unit configured to input a frame of a video; an object region detection unit configured to detect at least one object region by comparing a feature amount of the input frame and a feature amount of at least one background in the frame represented by background information in a background model; a selection unit configured to select a background object region including a background object which is originally included in the background, from the detected at least one object region by using at least one first condition to be satisfied by the background object; a discrimination unit configured to discriminate between a portion corresponding to the background object and a portion other than the background object in the background object region by using at least one second condition to be satisfied by a region which does not include the background object; a generation unit configured to generate background object feature information representing a feature amount of the background object based on feature amounts of the background object region and a result of discrimination by said discrimination unit; and an addition unit configured to add the background object feature information to the background model, thereby forcing said object region detection unit not to detect the background object as the object region from a succeeding frame.
