Abstract
An image processing apparatus includes: a reducing section reducing an image for which a feature analysis is to be perform at a predetermined reduction ratio; an ROI mask generating section analyzing a feature of a reduced image as the image reduced at the predetermined reduction ratio, and generating an ROI mask as mask information indicating a region of interest as a region to be interested in the reduced image; an ROI mask enlarging section enlarging a size of the ROI mask to a size of the image before being reduced by the reducing section; and an ROI mask updating section analyzing a feature of a region, set as a blank region as a region not to be interested in the ROI mask, of the image before being reduced by the reducing section, and updating the ROI mask by using an analysis result.
Claims10
An image processing apparatus, comprising:
- a reducing section reducing an image for which a feature analysis is to be carried out at a predetermined reduction ratio;
- an ROI mask generating section analyzing a feature of a reduced image as the image reduced at the predetermined reduction ratio by said reducing section, and generating an ROI mask as mask information indicating a region of interest as a region to be interested in the reduced image;
- an ROI mask enlarging section enlarging a size of said ROI mask generated by said ROI mask generating section to a size of the image before being reduced at the predetermined reduction ratio by said reducing section;
- and
- an ROI mask updating section analyzing a feature of a region, set as a blank region as a region not to be interested in said ROI mask, of the image before being reduced at the predetermined reduction ratio by said reducing section, and updating said ROI mask by using an analysis result;
- ROI standing for region of interest.
An image processing method for use in an image processing apparatus, comprising:
- reducing an image for which a feature analysis is to be carried out at a predetermined reduction ratio by a reducing section;
- analyzing a feature of a reduced image as the image reduced at the predetermined reduction ratio by said reducing section, and generating an ROI mask as mask information indicating a region of interest as a region to be interested in the reduced image by an ROI mask generating section;
- enlarging a size of said ROI mask generated by said ROI mask generating section to a size of the image before being reduced at the predetermined reduction ratio by an ROI mask enlarging section;
- and
- analyzing a feature of a region, set as a blank region as an area not to be interested in said ROI mask, of the image before being reduced at the predetermined reduction ratio, and updating said ROI mask by using an analysis result by an ROI mask updating section;
- ROI standing for region of interest.
