Apparatus, method, and program for detecting object from image

摘要

An image processing apparatus includes a detection unit configured to scan an input image and each of images at different resolutions, which are generated from the input image, by a predetermined-sized window to detect an object in the image, a storage unit configured to store a detection result of the detection unit, and a control unit configured to, if there is no free space in the storage unit to store a new detection result of the detection unit, store the new detection result instead of a detection result of an image at higher resolution than resolution of an image from which the new detection result is acquired.

1. An image processing apparatus comprising:
a processor; and memory; wherein the processor is configured to: generate a plurality of images at different resolutions from an input image; sequentially scan an input image and each of the plurality of images at the different resolutions, in descending order of the resolutions using a fixed-sized window to sequentially detect objects of different sizes in the input image in ascending order of the sizes of the objects; store a plurality of detection results of the detection in a predetermined number of storage areas in a storage unit; and write the sequentially detected objects in the predetermined number of storage areas circularly, such that if there is no free space in the predetermined number of storage areas to store a new detection result of a first object, the new detection result is overwritten on an old detection result of a second object which is smaller than the first object corresponding to the new detection result.
