System and method for classifying in vivo images according to anatomical structure
View Patent ↗A system for identifying anatomical structure depicted in an in vivo image, that includes an examination bundlette having a captured in vivo image; and a gastrointestinal atlas that includes a list of individual anatomical structures and characterization data of the individual anatomical structures. A classification engine analyzes the examination bundlette and the gastrointestinal atlas to identify the anatomical structure depicted in the captured in vivo image.
1. A system for identifying anatomical structure depicted in an in vivo image, comprising:
a) an examination bundlette that includes an in vivo image;
b) a gastrointestinal atlas that includes a list of individual anatomical structures and characterization data of the individual anatomical structures; and
c) a classification engine that analyzes the examination bundlette and the gastrointestinal atlas to identify the anatomical structure depicted in the in vivo image.
2. The system claimed in claim 1 , wherein the classification engine includes a classifier identifying the anatomical structure depicted in the in vivo image.
3. The system claimed in claim 2 , wherein the classifier is selected from the group consisting of k-nearest neighbor, linear, piecewise linear, quadratic, or polynomial discriminant functions, decision trees, neural networks, and support vector machines.
4. The system claimed in claim 1 , wherein the classification engine uses image based classification methods for analyzing the examination bundlette and the gastrointestinal atlas.
5. The system claimed in claim 1 , wherein the classification engine extracts image based features from the examination bundlette for comparison with image specific characterization data in the gastrointestinal atlas.
6. The system claimed in claim 1 , wherein the classification engine extracts non-image based features from the examination bundlette for comparison with non-image specific characterization data in the gastrointestinal atlas.
7. The system claimed in claim 5 , wherein the image specific characterization data is selected from the group consisting of representative images of the anatomical structure captured from various positions and orientations, from various illumination levels, color and/or texture distributions, and features of representative images of the anatomical structure.
8. The system claimed in claim 6 , wherein the non-image specific characterization data is selected from the group consisting of the average length or size of the anatomical structure, average relative position of the anatomical structure along the gastrointestinal tract and/or with respect to other anatomical structures, average pH, temperature, pressure levels of the anatomical structure, and average motility characteristics of the anatomical structure.
9. The system claimed in claim 1 , wherein the gastrointestinal atlas includes a list of anatomical structures selected from the group consisting of the mouth, pharynx, esophagus, cardiac orifice, stomach, pylorus, duodenum, jejunum, ileum, ileocecal valve, cecum, colon, rectum, and anus.
10. A method for identifying anatomical structure depicted in an in vivo image, the method being carried by an in vivo camera system and comprising the steps of
a) providing an examination bundlette that includes an in vivo image;
b) providing a gastrointestinal atlas that includes a list of individual anatomical structures and characterization data of the individual anatomical structures; and
c) analyzing the examination bundlette and the gastrointestinal atlas to identify the anatomical structure depicted in the in vivo image.
11. The method claimed in claim 10 , wherein the classification engine includes a classifier for identifying the anatomical structure depicted in the captured in vivo image.
12. The method claimed in claim 11 , wherein the classifier is selected from the group consisting of k-nearest neighbor, linear, piecewise linear, quadratic, or polynomial discriminant functions, decision trees, neural networks, and support vector machines.
13. The method claimed in claim 10 , wherein the classification engine uses image based classification methods for analyzing the examination bundlette and the gastrointestinal atlas.
14. The method claimed in claim 10 , wherein the classification engine extracts image based features from the examination bundlette for comparison with image specific characterization data in the gastrointestinal atlas.
15. The method claimed in claim 10 , wherein the classification engine extracts non-image based features from the examination bundlette for comparison with non-image specific characterization data in the gastrointestinal atlas.
16. The method claimed in claim 14 , wherein the image specific characterization data is selected from the group consisting of representative images of the anatomical structure captured from various positions and orientations, from various illumination levels, color and/or texture distributions, and features of representative images of the anatomical structure.
17. The method claimed in claim 15 , wherein the non-image specific characterization data is selected from the group consisting of the average length or size of the anatomical structure, average relative position of the anatomical structure along the gastrointestinal tract and/or with respect to other anatomical structures, average pH, temperature, pressure levels of the anatomical structure, and average motility characteristics of the anatomical structure.
18. The method claimed in claim 10 , wherein the gastrointestinal atlas includes a list of anatomical structures selected from the group consisting of the mouth, pharynx, esophagus, cardiac orifice, stomach, pylorus, duodenum, jejunum, ileum, ileocecal valve, cecum, colon, rectum, and anus.
19. A system for identifying anatomical structure depicted in an in vivo image, comprising:
a) an examination bundlette that includes a captured in vivo image;
b) a gastrointestinal atlas that includes a list of individual anatomical structures and characterization data of the individual anatomical structures; and
c) a means for analyzing the examination bundlette and the gastrointestinal atlas to identify the anatomical structure depicted in the captured in vivo image.
20. The system claimed in claim 19 , wherein the means for analyzing the examination bundlette and the gastrointestinal atlas includes a classifier for identifying the anatomical structure depicted in the captured in vivo image.
21. The system claimed in claim 20 , wherein the classifier is selected from the group consisting of k-nearest neighbor, linear, piecewise linear, quadratic, or polynomial discriminant functions, decision trees, neural networks, and support vector machines.
22. The system claimed in claim 19 , wherein the means for analyzing the examination bundlette and the gastrointestinal atlas uses image based classification methods for analyzing the examination bundlette and the gastrointestinal atlas.
23. The system claimed in claim 19 , wherein the means for analyzing the examination bundlette and the gastrointestinal atlas extracts image based features from the examination bundlette for comparison with image specific characterization data in the gastrointestinal atlas.
24. The system claimed in claim 19 , wherein the means for analyzing the examination bundlette and the gastrointestinal atlas extracts non-image based features from the examination bundlette for comparison with non-image specific characterization data in the gastrointestinal atlas.
