Abstract: An image processing method for tracking an object, the method includes: specifying a first range in which a first target is searched for and a second range in which a second target is searched for in a next frame by referring to a storage device that stores past frames captured by a capturing device; changing the first range and/or the second range in the next frame such that an area in which the first range and the second range specified in the next frame overlap each other is less than a predetermined value in a case where the overlapping area is equal to or greater than the predetermined value; and searching for, in the changed first range and the changed second range, and specifying a region corresponding to the first target and a region corresponding to the second target in the next frame.

Abstract: A determination method includes: receiving first sensing data that includes either video or voice generated in a first remote call made between a first account and a second account and second sensing data that includes either video or voice generated in a second remote call made between the first account and the second account; referring to a storage unit that stores feature information extracted when a specific situation for a person who corresponds to the first account occurs in the first sensing data in association with the specific situation when occurrence of the specific situation for the person who corresponds to the first account is detected in the second sensing data; and making determination related to spoofing on a basis of a matching state between the feature information for the specific situation in the storage unit and the feature information for the specific situation detected from the second sensing data.

Abstract: A moving object group detection method includes: respectively analyzing a first captured image captured by a first image capture device and a second captured image captured by a second image capture device, and respectively extracting a first image region and a second image region from the first captured image and the second captured image, the first image region and the second image region being regions in which coloring patterns satisfy a predetermined similarity range and moving in corresponding directions over plural frames; and detecting that a common moving object group is included in the first image region and the second image region on the basis of an evaluation of similarity between an image within the first image region and an image within the second image region.

Abstract: A non-transitory computer-readable storage medium storing an image processing device that causes a computer to execute a process includes: individually detecting, as a detection target candidate, a first portion of each of detection targets that appear in an image imaged by an imaging device, by using a first detection area corresponding to the first portion; detecting a detection target for a detection target candidate corresponding to a detection target that is not covered by another detection target and that is included in the detected detection target candidates, by using a second detection area corresponding to a second portion including the first portion; and detecting a detection target for a detection target candidate corresponding to a detection target, covered by another detection target and included in the detected detection target candidates, by using a third detection area that corresponds to a third portion including the first portion.

Abstract: A determination apparatus calculates, based on a first data group which includes data indicating behaviors of people, reference behavior data indicating a reference behavior among the people about each of a plurality of types of behaviors, acquires, from the first data group, first behavior data indicating a behavior of a first person about each behavior type, calculates difference between the first behavior data and the reference behavior data about each behavior type, determines, from the plurality of types, at least one first type whose difference is at least a first threshold, registers second behavior data indicating a behavior of the first person about each first type in a second data group, extracts third behavior data indicating a behavior of a second person from an input image, and determines whether the second person is identical with the first person based on comparison between the third and second behavior data.

Abstract: An image processing device includes a processor that executes a procedure. The procedure includes: generating a manipulated image by executing first manipulation processing on an input image so as to anonymize information contained in the input image; generating a reconstructed image by performing reconstruction processing on the manipulated image to reconstruct the information; and, based on a comparison between the input image and the reconstructed image, determining whether or not to execute second manipulation processing on the input image or on the manipulated image to anonymize the information, wherein the second manipulation processing is different from the first manipulation processing.
