Abstract

Image analysis is executed by the use of an image representing an object. The image has image processing information, on image processing which the image has undergone, attached to the image. The image processing information attached to the image is obtained from the image and the image is corrected on the basis of the image processing information so that the image approaches to an image optimal to the image analysis. The image analysis is executed by the use of the corrected image.

Claims

1. A method of image processing for executing an image analysis comprising:

attaching image enhancement processing information to an image processed for enhancement specifying image enhancement processing which the image has undergone;

obtaining from the image, with image processing information obtaining means of a system for executing an image analysis, the image enhancement processing information attached thereto;

correcting the image on the basis of the image enhancement processing information so that the image approaches to an image optimal to the image analysis; and

executing image analysis on the corrected image.

13. The method of claim 1, wherein the image is corrected based on the image enhancement processing information to produce a corrected image approximately the same as before the image enhancement processing was applied.

15. The system of claim 1, wherein enhancement processing comprises a visually perceptible enhancement.

2. A system for executing an image analysis comprising:

image enhancement processing information obtaining means which obtains image enhancement processing information attached to an image processed for enhancement specifying image enhancement processing which the image has undergone;

correction means which corrects the image on the basis of the image enhancement processing information so that the image approaches to an image optimal to the image analysis; and

image analysis means which analyzes the corrected image.

3. A system for executing image processing as defined in claim 2 wherein the image suitable for image analysis is an image before the image enhancement processing is carried out,

wherein the image enhancement processing information includes processing check information which represents whether the image is a processed image which has undergone image enhancement processing, and if the image is a processed image includes processing condition information which represents the condition under which the image enhancement processing has been carried out on the image, and

wherein the correcting means determines on the basis of the processing check information whether the image is a processed image and if the image is a processed image carries out image processing reverse to the image enhancement processing which the image has undergone on the basis of the processing condition information.

4. A system for executing image processing as defined in claim 2 wherein the image enhancement processing information includes processing check information which represents whether the image is a processed image which has undergone image enhancement processing, and the correcting means determines on the basis of the processing check information whether the image is a processed image and carries out on an image which is determined to be a processed image processing reverse to a representative of image enhancement processing which the image has undergone,

wherein the image suitable for image analysis is an image before the image processing is carried out.

5. A system for executing image processing as defined in claim 2 in which the image suitable for image analysis is an image having a specified property, the image enhancement processing information is an image pattern in the image which consists of a plurality of density regions which are set so that each of the density regions has a specified density in the image and reflects the image enhancement processing which the image has undergone, and the correcting means carries out gradation transformation on the image so that each of the density regions in the image pattern has the specified density.

6. A system for executing image processing as defined in claim 5 in which the specified image property is that under which the relation between the density of the image and a specified parameter corresponding to the density of the image is logarithmic-linear.

7. A system for executing image processing as defined in claim 2 in which the image enhancement processing includes gradation processing.

8. A system for executing image processing as defined in claim 2 in which the image enhancement processing includes frequency processing.

9. A system for executing image processing as defined in claim 2 in which the image is a medical image and the image analysis is abnormal shadow detection.

10. A system for executing image processing as defined in claim 2 in which the image is a medical image and the image analysis is similar image retrieval.

11. A system for executing image processing as defined in claim 2 in which the image is a medical image and the image analysis is artificial image generation.

14. The system of claim 2, wherein the correction means corrects the image based on the image enhancement processing information to produce a corrected image approximately the same as before the image processing was applied.

12. A tangible computer readable medium having stored therein a program for causing a computer to execute image processing, said program including computer executable instructions for performing steps comprising:

inputting an image having attached to thereto image enhancement processing information related to image enhancement processing which the image has undergone;

obtaining the attached image enhancement processing information from the image;

correcting the image on the basis of the image enhancement processing information so that the image approaches an image suitable for image analysis; and

executing specified image analysis on the corrected image.
