Method for automatically detecting degenerated regions in stained thin section slides
First Claim
1. A method for detecting a degenerated region comprising:
- obtaining color region information on a degenerated region on image data of a standard specimen in a stained thin section slide;
obtaining color region information on a non-degenerated region on the image data of the standard specimen;
obtaining color region information on a non-degenerated region on image data of a specimen;
comparing the image data of the specimen with the image data of the standard specimen to calculate a color correction quantity to match tone and brightness of the non-degenerated region in the specimen with the counterparts of the non-degenerated region in the standard specimen, and correcting the image data of the specimen with the color correction quantity; and
extracting a degenerated region in the corrected image data of the specimen based on the color region information of the degenerated region in the standard specimen.

Abstract
In a method for automatically detecting degenerated regions in many stained thin section specimens (40), color region information is obtained on a degenerated region and on a non-degenerated region on image data of a standard specimen in a stained thin section slide. Next, color region information is obtained on a non-degenerated region on image data of a specimen. Next, the image data of the specimen is compared with the image data of the standard specimen to calculate a color correction quantity to match tone and brightness of the non-degenerated region in the specimen with the counterparts in the non-degenerated region in the standard specimen, and the image data of the specimen is corrected with the color correction quantity. Next, a degenerated region is extracted in the corrected image data of the specimen based on the color region information in the standard specimen.
