Abstract: To provide an image processing system, an image processing method, and a program, capable of detecting a group with high irregularity. An image processing system is provided with: a group detector that detects a group based on an input image captured with an image capturing at a first time; a repeating group analyzer that determines that a detected group has been previously detected; and an alert module that reports when the detected group has been determined by the repeating group analyzer to have been previously detected.

Abstract: An object information extraction apparatus (2000) includes an image acquisition unit (2020), a frequency determination unit (2040), and an information extraction unit (2060). The image acquisition unit (2020) acquires a plurality of images corresponding to a predetermined unit time of a video. The frequency determination unit (2040) generates frequency information for each of a plurality of partial areas included in each of a plurality of images. The information extraction unit (2060) extracts information of an object included in each partial area from each image corresponding to the number indicated by the frequency information for each partial region among a plurality of images corresponding to a predetermined unit time for each partial area.

Abstract: Although persons on board in a driver's seat and a passenger seat can be detected, it is difficult to detect persons on board in a back seat and thus the number of passengers cannot be accurately measured. Image obtaining means 100 photographs the inside of a vehicle from the outside of the vehicle (a shoulder, etc.). View determining means 102 estimates the way in which the vehicle in the image photographed by the image obtaining means 100 is viewed, and outputs a view determination result. Person detecting means 101 performs front-face, side-face, and angled-face detection on the image photographed by the image obtaining means 100, to detect persons and outputs a person detection result. In-vehicle position estimating means 103 determines at which positions in the vehicle the detected persons are present, using the person detection information and the view determination result information, and outputs in-vehicle position estimation information. Result integrating means 104 integrates detection results obtained for a plurality of images which are photographed consecutively, to calculate the number of passengers.

Abstract translation: 虽然可以检测到驾驶员座椅和乘客座椅上的人员，但是难以在后座检测船上的人员，因此无法准确地测量乘客人数。 图像获取装置100从车辆的外部（肩部等）拍摄车辆的内部。 视图确定装置102估计由图像获取装置100拍摄的图像中的车辆的方式，并输出视图确定结果。 人物检测装置101对由图像获取装置100拍摄的图像执行正面，侧面和角度面检测，以检测人并输出人物检测结果。 车内位置估计装置103使用人检测信息和视图确定结果信息来确定车辆中哪个位置存在检测到的人，并输出车内位置估计信息。 结果积分装置104对连续拍摄的多张图像的检测结果进行积分，计算乘客人数。
