Object detection device, object detection method, and program

Abstract

The objective is to provide a technology that efficiently improves the detection accuracy of objects that are difficult to detect due to their size when being imaged. [Solution] One aspect of the present disclosure relates to an object detection device comprising: an acquisition unit for acquiring an image to be processed; an extraction unit for extracting candidate regions in the image to be processed; a generation unit for generating a reconstructed image composed of the candidate regions; a detection unit for detecting objects from the reconstructed image; and an output unit for outputting a processing result of the image to be processed based on the detection result.
