Abstract
In an image processing device, image data is divided into a plurality of band data including first and second band data. The first band data and the second band data have an overlap region, from which the first and second regions are extracted, respectively. The first region and the second region at least partially overlap with each other in the overlap region and have attributes different from each other, and the respective feature amounts are calculated. Based on these feature amounts, an attribute to be used for correction is decided. Then, an attribute different from the decided attribute between the attribute of the first region and the attribute of the second region is changed to the decided attribute.
Claims18
An image processing device comprising:
- a division unit dividing image data into a plurality of band data in such a manner as to have an overlap region where adjacent band data overlap with each other;
- a region identification unit extracting a region from each of said plurality of band data for each of different kinds of attributes, said plurality of band data including first band data and second band data having said overlap region;
- a region extractor extracting a first region from said region extracted from said first band data and extracting a second region from said region extracted from said second band data, wherein said first region and said second region at least partially overlap with each other in said overlap region and have attributes different from each other;
- a first feature amount calculator calculating a feature amount of extracted said first region;
- a second feature amount calculator calculating a feature amount of extracted said second region;
- an attribute decision unit deciding on any one of an attribute of said first region and an attribute of said second region for use in correction, based on the feature amount of said first region and the feature amount of said second region;
- and
- a correction unit changing an attribute different from said decided attribute, of the attribute of said first region and the attribute of said second region, to said decided attribute.
An image processing method comprising the steps of:
- dividing image data into a plurality of band data in such a manner as to have an overlap region where adjacent band data overlap with each other;
- extracting a region from each of said plurality of band data for each of different kinds of attributes, said plurality of band data including first band data and second band data having said overlap region;
- extracting a first region from said region extracted from said first band data and extracting a second region from said region extracted from said second band data, wherein said first region and said second region at least partially overlap with each other in said overlap region and have attributes different from each other;
- calculating a feature amount of extracted said first region;
- calculating a feature amount of extracted said second region;
- deciding on any one of an attribute of said first region and an attribute of said second region based on the feature amount of said first region and the feature amount of said second region;
- and
- changing an attribute different from said decided attribute, of the attribute of said first region and the attribute of said second region, to said decided attribute.
A program product causing a computer to execute image processing, said computer being caused to execute the steps of:
- dividing image data into a plurality of band data in such a manner as to have an overlap region where adjacent band data overlap with each other;
- extracting a region from each of said plurality of band data for each of different kinds of attributes, said plurality of band data including first band data and second band data having said overlap region;
- extracting a first region from said region extracted from said first band data and extracting a second region from said region extracted from said second band data, wherein said first region and said second region at least partially overlap with each other in said overlap region and have attributes different from each other;
- calculating a feature amount of extracted said first region;
- calculating a feature amount of extracted said second region;
- deciding on any one of an attribute of said first region and an attribute of said second region based on the feature amount of said first region and the feature amount of said second region;
- and
- changing an attribute different from said decided attribute, of the attribute of said first region and the attribute of said second region, to said decided attribute.
