Abstract
The invention relates to an object number estimation device, an object number estimation method, and a storage medium, which can estimate the number of objects with high precision. An object number estimation device is provided with an acquisition unit, a setting unit, and an estimation unit. Acquisition unit acquires image. The setting unit sets a local region size, which is an object number estimation unit in the image, on the basis of the image. The estimation unit estimates the number of objects included in the image for each local region of a set local region size.
Description
[0001] This application is based on Japanese invention patent application 2019-161610 (filing date: September 4, 2019), and enjoys the priority of this application. This application incorporates the entire contents of this application by reference thereto. technical field [0002] Embodiments of the present invention relate to an object number estimating device, an object number estimating method, and a storage medium. Background technique [0003] There is known a method of analyzing an image obtained by a surveillance camera and the like to estimate the number of persons included in the image. For example, a learning model is learned using the correspondence between images and correct labels representing the state of the crowd and the location of the crowd reflected in the image as teacher data. Furthermore, a technique for estimating the position of a crowd from an image using the learning model is disclosed. Also, in the prior art, objects included in an image are esti...
