Abstract
Described herein is a computer-aided technology for facilitating detection of folds of an object surface. In one implementation, image data is processed to determine curvature characteristics at one or more points of the surface of a region of interest. If the curvature characteristics of one of the one or more points correspond to a hyperbolic curvature, the point is identified as a seed point. A region of a predetermined thickness is grown around the seed point so as to detect the presence of any fold feature within the grown region.
Claims20
A method of detecting folds in a digitized medical image, comprising:
- receiving image data including a region of interest;
- calculating curvature characteristics at one or more points corresponding to a surface of the region of interest;
- identifying at least one of the one or more points as a seed point if its curvature characteristics correspond to a hyperbolic curvature;
- and
- detecting a fold by growing a region around the seed point to a predetermined thickness and identifying at least one fold feature within the region.
A non-transitory computer readable medium embodying a program of instructions executable by a machine to perform steps for detecting folds within a digitized medical image, the steps comprising:
- receiving image data including a region of interest;
- calculating curvature characteristics at one or more points corresponding to a surface of the region of interest;
- identifying at least one of the one or more points as a seed point if its curvature characteristics correspond to a hyperbolic curvature;
- and
- detecting a fold by growing a region around the seed point to a predetermined thickness and identifying at least one fold feature within the region.
An image analysis system, comprising:
- a memory device for storing computer readable program code;
- and
- a processor in communication with the memory device, the processor being operative with the computer readable program code to:
- receive image data including a region of interest;
- calculate curvature characteristics at one or more points corresponding to a surface of the region of interest;
- identify at least one of the one or more points as a seed point if its curvature characteristics correspond to a hyperbolic curvature;
- and
- detect a fold by growing a region around the seed point to a predetermined thickness and identifying at least one fold feature within the region.
