Abstract: A control apparatus (103) includes a history acquisition unit (104) and a control unit (105). The history acquisition unit (104) processes image information including an image in which a target space is captured, and acquires appearance history information (106a) including a history of appearances of one or more persons being active in the target space. The control unit (105) outputs control information for controlling an air conditioner (102), based on the appearance history information (106a).

Abstract: A ground truth weight generation unit generates a ground truth weight for each piece of tracking object data of tracking object information regarding a tracking object by using ground truth tracking object pair information that is a set of tracking object information of the same tracking object or a set of tracking object information of separate tracking objects. An inference model training unit trains, by machine learning, an inference model that outputs a tracking object data weight corresponding to tracking object data included in the tracking object information by using data regarding the tracking object information as input data and using a ground truth weight generated for the tracking object information as ground truth data.

Abstract: To utilize a result of image analysis, an image analysis apparatus 100 includes an analysis result acquisition unit 110 and a counting unit 111. The analysis result acquisition unit 110 acquires analysis information being information acquired by analyzing a still image and including an appearance attribute to which a person included in the still image belongs. The counting unit 111 counts, for each appearance attribute, the number of persons belonging to the appearance attribute in the still image by using the analysis information, and generates counting information indicating a result of the counting in units of still images.
