Image processing apparatus, image processing method, and computer-readable, non-transitory medium
First Claim
1. An image processing apparatus comprising:
- a decimated image generator for generating a decimated image through pixel decimation from an input image;
an edge pixel extractor for extracting edge pixels from said decimated image;
an edge class extractor for extracting an isolated edge pixel from among said edge pixels;
a histogram generator for generating an isolated histogram from only said isolated edge pixel; and
a decision unit for making, based on said isolated histogram, a decision as to whether or not said input image contains a background element.

Abstract
There are provided an image processing apparatus, image processing method, and a computer-readable, non-transitory medium that can determine with high accuracy whether or not an input image contains a background element. The image processing apparatus includes a decimated image generator for generating a decimated image through pixel decimation from an input image, an edge pixel extractor for extracting edge pixels from the decimated image, an edge class extractor for extracting an isolated edge pixel from among the edge pixels, a histogram generator for generating an isolated histogram based on the isolated edge pixel, and a decision unit for making, based on the isolated histogram, a decision as to whether or not the input image contains a background element.

8. A computer-readable, non-transitory medium storing a computer program, wherein said computer program causes a computer to execute a process, the process comprising:
-
generating a decimated image through pixel decimation from an input image; extracting edge pixels from said decimated image; extracting an isolated edge pixel from among said edge pixels; generating an isolated histogram from only said isolated edge pixel; and based on said isolated histogram, making a decision as to whether or not said input image contains a background element.
