IMAGE PROCESSING APPARATUS, REGION DETECTION METHOD AND COMPUTER-READABLE, NON-TRANSITORY MEDIUM |
| 摘要 |
An image processing apparatus includes a color component image generator for extracting a particular color component from an input image to generate a color component image, an expanded-color-component image generator for expanding particular pixels in the color component image to generate an expanded-color-component image, an edge pixel extractor for extracting edge pixels from the expanded-color-component image, and a document region detector for detecting a document region from the edge pixels. |
