Abstract
An image processing apparatus includes an input unit configured to input an image, a determining unit configured to determine a foreground area and a background area in the image input by the input unit, an expansion unit configured to expand the foreground area determined by the determining unit, a calculating unit configured to calculate a feature amount of the foreground area expanded by the expansion unit, and a detecting unit configured to detect an object from the image using the feature amount.
Claims7
An image processing apparatus, comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
- inputting an image;
- determining a foreground area and a background area in the input image;
- reducing the input image at a plurality of reduction rates;
- expanding the foreground area with respect to each of a plurality of reduced images obtained by reducing the input image at the plurality of reduction rates, by adding, to the foreground area, a surrounding area which is required for obtaining a feature amount of a boundary between the background area and the foreground area;
- calculating a feature amount of the expanded foreground area;
- and
- detecting an object from the foreground area using the feature amount of the expanded foreground area.
