Abstract
An image processing apparatus includes a dividing unit configured to divide an image into a plurality of regions based on an attribute of a pixel, the image having an image coordinate system set therein; a converting unit configured to set a region coordinate system for each of the regions obtained by the dividing unit and to convert coordinate values of a pixel in the image on the image coordinate system into coordinate values on the region coordinate system set for a region to which the pixel belongs; and a calculating unit configured to calculate a feature amount of the region by using the converted coordinate values.

An image processing apparatus, comprising:
- a dividing unit configured to divide an image into a plurality of regions based on an attribute of a pixel, the image having an image coordinate system set therein;
- a converting unit configured to set a region coordinate system for each of the regions obtained by the dividing unit and to convert coordinate values of a pixel in the image on the image coordinate system into coordinate values on the region coordinate system set for a region to which the pixel belongs;
- and
- a calculating unit configured to calculate a feature amount of the region by using the converted coordinate values.
An image processing method, comprising:
- dividing an image into a plurality of regions based on an attribute of a pixel, the image having an image coordinate system set therein;
- setting a region coordinate system for each of the divided regions and converting coordinate values of a pixel in the image on the image coordinate system into coordinate values on the region coordinate system set for a region to which the pixel belongs;
- and
- calculating a feature amount of the region by using the converted coordinate values.
A non-transitory computer-readable storage medium storing a program that causes a computer to function as:
- a dividing unit configured to divide an image into a plurality of regions based on an attribute of a pixel, the image having an image coordinate system set therein;
- a converting unit configured to set a region coordinate system for each of the regions obtained by the dividing unit and to convert coordinate values of a pixel in the image on the image coordinate system into coordinate values on the region coordinate system set for a region to which the pixel belongs;
- and
- a calculating unit configured to calculate a feature amount of the region by using the converted coordinate values.
