Abstract: An information processing system includes a processor that performs an object detection to detect an object from a detection target image. The processor divides the detection target image into a group of first grid cells. The object is positioned to overlap a group of second grid cells included in the group of the first grid cells. At this time, the processor generates a bounding box in a respective second grid cell included in the group of the second grid cells. The processor surrounds a portion of the object positioned in the respective second grid cell with the bounding box generated in the respective second grid cell and displays, on a display, a position and shape of the object by a collection of a plurality of bounding boxes superimposedly on the detection target image.
