Abstract

A hybrid detection model may be used for breast cancer detection. A system can identify a region of interest on a received mammogram. The region of interest may have a particular level of grey at each pixel of the image. A morphological and entropy filter may then each be applied to the region of interest. Based on the filters, the system may generate a hybrid result that is the average of a combination of the two filters. The system may then segment the region of interest using a selected clustering algorithm.

Claims (34)

1. A computer-implemented method for a hybrid detection model for use in breast cancer detection, the method comprising:

applying, to each level of grey for each pixel in a region of interest in a digital image, a predetermined morphological filter, wherein the morphological filter reduces grey levels of the digital image to generate a first set of values;

applying, to each level of grey for each pixel in the region of interest in the digital image, a predetermined entropy filter to capture a set of maximum grey values, wherein the maximum grey values reflect a local maximum relative to other grey values in the digital image;

generating a hybrid result that is a combination of the outputs of the predetermined morphological filter and the predetermined entropy filter; and

segmenting, using the hybrid result, the digital image into potential problem areas.

2. The method of claim 1 , wherein the segmenting includes using a selected clustering algorithm with sub-segmentation.

3. The method of claim 1 , further comprising displaying, on a user interface, the segmented digital image.

4. The method of claim 1 , further comprising capturing, by a mammogram capture device, the digital image.

5. The method of claim 4 , wherein the capturing and applying of each of the predetermined morphology filter and the predetermined entropy filter, are performed by a same device, and wherein the device includes the mammogram capture device.

6. The method of claim 5 , wherein the device is a smart phone.

7. The method of claim 1 , wherein the digital image is a mammogram.

8. The method of claim 1 , wherein the potential problem areas are a set of microcalcifications.

9. A computer system comprising:

a computer readable storage medium with program instructions stored thereon; and

one or more processors configured to execute the program instructions to perform a method comprising:

applying, to each level of grey for each pixel in a region of interest in a digital image, a predetermined morphological filter, wherein the morphological filter reduces grey levels of the digital image to generate a first set of values;

applying, to each level of grey for each point in the region of interest in the digital image, a predetermined entropy filter to capture a set of maximum grey values, wherein the maximum grey values reflect a local maximum relative to other grey values in the digital image;

generating a hybrid result that is a combination of the outputs of the predetermined morphological filter and the predetermined entropy filter; and

segmenting, using the hybrid result, the digital image into potential problem areas.

10. The system of claim 9 , wherein the segmenting includes using a selected clustering algorithm with sub-segmentation.

11. The system of claim 9 , wherein the method further comprises displaying, on a user interface, the segmented digital image.

12. The system of claim 9 , wherein the method further comprises capturing, by a mammogram capture device, the digital image.

13. The system of claim 9 , wherein the system further comprises a mammogram capture device.

14. The system of claim 9 , wherein the method further comprises accessing, prior to the identifying, the digital image from a database.

15. The system of claim 9 , wherein the digital image is a mammogram.

16. The system of claim 9 , wherein the potential problem areas are microcalcifications.

17. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a computer processor to cause the processor to perform a method comprising:

applying, to each level of grey for each pixel in a region of interest in a digital image, a predetermined morphological filter, wherein the morphological filter reduces grey levels of the digital image to generate a first set of values;

applying, to each level of grey for each point in the region of interest in the digital image, a predetermined entropy filter to capture a set of maximum grey values, wherein the maximum grey values reflect a local maximum relative to other grey values in the digital image;

generating a hybrid result that is a combination of the outputs of the predetermined morphological filter and the predetermined entropy filter; and

segmenting, using the hybrid result, the digital image into potential problem areas.

18. The computer program product of claim 17 , wherein the segmenting includes using a selected clustering algorithm with sub-segmentation.

19. The computer program product of claim 17 , wherein the method further comprises displaying, on a user interface, the segmented digital image.

20. The computer program product of claim 17 , wherein the method further comprises capturing, by a mammogram capture device, the digital image.
