A device and method for extracting a plurality of tile images from specimen cytology slide images divided according to a cell staining method, and classifying a class of at least one of a type of cancer and whether there is cancer according to a cell staining method in any specimen cytology slide image using a prediction model that has undergone annotation-based learning on the specimen cytology slide images or the tile images.
- Claim:
1. A specimen cytology supporting device according to a cell staining method, comprising: a pre-processor extracting a plurality of tile images from a specimen cytology slide image divided according to the cell staining method; and a classifier classifying a class of at least one of whether there is cancer and a type of cancer according to the cell staining method in any specimen cytology slide image using a prediction model that has undergone annotation-based using the specimen cytology slide image divided according to the cell staining method or the plurality of tile images.
- Claim:
2. The specimen cytology supporting device of claim 1, wherein the cell staining method may be one of Giemsa staining, hematoxylin-eosin (H&E) staining, NissI staining, reticulin staining, Papanicolaou (PAP) staining, and Diff-quik staining.
- Claim:
3. The specimen cytology supporting device of claim 2, wherein there are a plurality of prediction models that have undergone annotation-based learning for each cell staining method of the specimen and for each type of cancer, and wherein the classifier classifies a class of at least one of whether there is cancer or the type of cancer according to each cell staining method in any specimen cytology slide image using each prediction model that has undergone the annotation-based learning for each cell staining method of the specimen and for each type of cancer.
- Claim:
4. The specimen cytology supporting device of claim 1, wherein the specimen cytology slide image is obtained by applying Z-stacking or focus stacking to an original slide image obtained by spearing and capturing or scanning on a glass slide of the specimen.
- Claim:
5. The specimen cytology supporting device of claim 4, wherein the specimen cytology slide image is obtained by synthesizing images focused at different phases from the original slide image into one image through secondary post-processing, using Z-stacking or focus stacking.
- Claim:
6. The specimen cytology supporting device of claim 1, wherein the pre-processor generates the plurality of tile images based on a sliding window algorithm.
- Claim:
7. The specimen cytology supporting device of claim 1, wherein the prediction model that has undergone the annotation-based learning undergoes learning by adding one or more of a partial annotation indicating a cancer area in a line form, a bounding box annotation indicating the cancer area in a box form, and an image-level label indicating a whole image to the specimen cytology slide image divided according to the cell staining method or the plurality of tile images used for learning.
- Claim:
8. A specimen cytology supporting method according to a cell staining method, comprising: a pre-processing step extracting a plurality of tile images from a specimen cytology slide image divided according to the cell staining method; and a classification step classifying a class of at least one of whether there is cancer and a type of cancer according to the cell staining method in any specimen cytology slide image using a prediction model that has undergone annotation-based learning using the specimen cytology slide image divided according to the cell staining method or the plurality of tile images.
- Claim:
9. The specimen cytology supporting method of claim 8, wherein the cell staining method may be one of Giemsa staining, hematoxylin-eosin (H&E) staining, NissI staining, reticulin staining, Papanicolaou (PAP) staining, and Diff-quik staining.
- Claim:
10. The specimen cytology supporting method of claim 9, wherein there are a plurality of prediction models that have undergone annotation-based learning for each cell staining method of the specimen and for each type of cancer, and wherein the classification step classifies a class of at least one of whether there is cancer or the type of cancer according to each cell staining method in any specimen cytology slide image using each prediction model that has undergone the annotation-based learning for each cell staining method of the specimen and for each type of cancer.
- Claim:
11. The specimen cytology supporting method of claim 8, wherein the specimen cytology slide image is obtained by applying Z-stacking or focus stacking to an original slide image obtained by spearing and capturing or scanning on a glass slide of the specimen.
- Claim:
12. The specimen cytology supporting method of claim 11, wherein the specimen cytology slide image is obtained by synthesizing images focused at different phases from the original slide image into one image through secondary post-processing, using Z-stacking or focus stacking.
- Claim:
13. The specimen cytology supporting method of claim 8, wherein the pre-processing step generates the plurality of tile images based on a sliding window algorithm.
- Claim:
14. The specimen cytology supporting method of claim 8, wherein the prediction model that has undergone the annotation-based learning undergoes learning by adding one or more of a partial annotation indicating a cancer area in a line form, a bounding box annotation indicating the cancer area in a box form, and an image-level label indicating a whole image to the specimen cytology slide image divided according to the cell staining method or the plurality of tile images used for learning.
- Claim:
15. A computer device, comprising: a memory storing a specimen cytology slide image divided according to a cell staining method, a plurality of tile images extracted from the specimen cytology slide image, and a prediction model, the prediction model being a prediction model that has undergone annotation-based learning to classify a class of at least one of whether there is cancer or a type of cancer according to the cell staining method in any specimen cytology slide image using the specimen cytology slide image divided according to the cell staining method or the plurality of tile images; and a processor, when receiving a request for classifying a class of at least one of whether there is cancer and the type of cancer in any specimen cytology slide image, extracting the plurality of tile images from the specimen cytology slide image, and executing the prediction model that has undergone the annotation-based learning stored in the memory to classify a class of at least one of whether there is cancer or the type of cancer according to the cell staining method in the specimen cytology slide image.
