Patent Images
1. A method of detecting particular regions, comprising:
- detecting one or more particular region candidates in a first image;
performing face detection in a region including at least one of the thus detected one or more particular region candidates by using a second image having a scene as same as said first image in which said one or more particular region candidates are detected, but being different in resolution from said first image; and
specifying as a particular region of a detection target a particular region candidate that is included in said region where a face can be detected.

Abstract
The method and apparatus for detecting particular regions detect one or more particular region candidates in a first image, perform face detection in a region including at least one of the thus detected particular region candidates by using a second image having a scene as same as the first image in which the particular region candidates are detected, but being different in resolution from the first image, and specify as a particular region of a detection target a particular region candidate that is included in the region where a face can be detected. The program for detecting particular regions causes a computer to execute the method.

7. A method of detecting particular regions, comprising:
-
detecting one or more particular region candidates from a first image in fed image data;
performing, prior to detection of said one or more particular region candidates, clipping processing of a face region for using to image density correction using a second image having a scene as same as said first image in which said one or more particular region candidates are detected, but being different in resolution from said first image;
checking whether or not one of said one or more particular region candidates is included within said face region clipped by said face region clipping processing; and
specifying as a particular region of a detection target a particular region candidate that is included within said face region.

8. An apparatus for detecting particular regions, comprising:
-
candidate detection means for detecting one or more particular region candidates from a first image in fed image data;
face detection means for detecting a face in a region including said one or more particular region candidates detected by said candidate detection means by using a second image having a scene as same as said first image in which said one or more particular region candidates are detected by said candidate detection means, but being different in resolution from said first image; and
specifying means for specifying as a particular region of a detection target a particular region candidate that is included in said region where a face can be detected by said face detection means. - View Dependent Claims (9, 10, 11, 12)

13. An apparatus for detecting particular regions, comprising:
-
candidate detection means for detecting one or more particular region candidates from a first image in fed image data;
face detection means for performing, before said one or more particular region candidates is detected in said candidate detection means, clipping processing of a face region for using to image density correction using a second image having a scene as same as said first image in which said one or more particular region candidates are detected in said candidate detection means, but being different in resolution from said first image; and
specifying means for checking whether or not one of said one or more particular region candidates detected by said candidate detection means is included within said face region clipped by said face detection means, and specifying as a particular region of a detection target a particular region candidate that is included within said face region.

14. A program for detecting particular regions, which causes a computer to execute:
-
a candidate detection step of detecting one or more particular region candidates from a first image in fed image data;
a face detection step of detecting a face in a region including said one or more particular region candidates detected in said candidate detection step by using a second image having a scene as same as said first image in which said one or more particular region candidates are detected in said candidate detection step, but being different in resolution from said first image; and
a specifying step of specifying as a particular region of a detection target a particular region candidate that is included in said region where a face can be detected in said face detection step. - View Dependent Claims (15, 16, 17, 18, 19)

20. A program for detecting particular regions, which causes a computer to execute:
-
a candidate detection step of detecting one or more particular region candidates from a first image in fed image data;
a face detection step of performing, before said one or more particular region candidates is detected in said candidate detection means, clipping processing of a face region for using to image density correction using a second image having a scene as same as said first image in which said one or more particular region candidates are detected in said candidate detection step, but being different in resolution from said first image;
a checking step of checking whether or not one of said one or more particular region candidates detected by said candidate detection step is included within said face region clipped by said face detection step; and
a specifying step of specifying as a particular region of a detection target a particular region candidate that is included within said face region.
