Object detection device, object detection method, and object detection program

An object detection method comprising:

• predicting an object presence area, which is an area where an object is present in a current image, which is an image of the object captured at a predetermined time, based on results of object detection in a past image, which is an image of the object captured in the past than at the predetermined time;
• generating an object presence partial area that includes a partial area of the predicted object presence area together with partial information, which is information indicating a position of the partial area in the predicted object presence area and a size of the partial area;
• detecting partial objects that are part of the object by performing object detection on the generated object presence partial area;
• and
• restoring results of object detection in the current image by placing the partial objects detected using the generated partial information in the predicted object presence area.

A computer-readable recording medium recording an object detection program causing a computer to execute:

• predicting an object presence area, which is an area where an object is present in a current image, which is an image of the object captured at a predetermined time, based on results of object detection in a past image, which is an image of the object captured in the past than at the predetermined time;
• generating an object presence partial area that includes a partial area of the predicted object presence area together with partial information, which is information indicating a position of the partial area in the predicted object presence area and a size of the partial area;
• detecting partial objects that are part of the object by performing object detection on the generated object presence partial area;
• and
• restoring results of object detection in the current image by placing the partial objects detected using the generated partial information in the predicted object presence area.
