Abstract: An image processing apparatus comprising one or more memories storing instructions and one or more processors that execute the instructions to acquire first information including likelihoods of tracking targets in a plurality of first candidates of the tracking target in a target image by using a tracking technique for tracking an object in an image, acquire second information including likelihoods of tracking targets in a plurality of second candidates of the tracking target in the target image by using a detection technique for detecting an object in an image, generate a determination reference for determining, based on the first information and the second information, whether a state is a lost state in which it is not possible to specify a tracking target, and determine, using the determination reference, whether the target image is set in a lost state.

Abstract: An information processing apparatus sets a first area and a second area corresponding to image areas of a tracking target, which are different from each other, for a template image included in a video sequence and including an image of the tracking target. The apparatus extracts a first area feature and a second area feature from the first area and the second area using a feature extraction NN, extracts a search area feature from a search area image using the feature extraction NN, and performs correlation calculation and deriving a first feature correlation map and a second feature correlation map. The apparatus integrates the first feature correlation map and the second feature correlation map and deriving an integrated feature, and detects the tracking target from the search area image based on the integrated feature.
