Accurate subvoxel edge location for 3D images
Version 1.0.4 (506 KB) by
Agustin Trujillo-Pino
Detection of subvoxel edges with very high precision in 3D images
This is the Matlab source code of the subvoxel edge detection method for 3D images, as detailed in the paper “Accurate Subvoxel Location and Characterization of Edges in 3D Images Based on the Partial Volume Effect”, (if you are interested in the code of 2D subpixel detector, go to this other link).
The main folder contains the following files:
- subvoxelEdges is the detection method. Type help subvoxelEdges for more info
- visEdges is the method for displaying detected edges over the image
- subsetEdges extracts a subset of edges that fulfill condition
- readanalyze reads images in Analyze format (.hdr)
- example1 is an example of edge detection of a synthetic sphere
- example2 is similar but with another synthetic objects
- example3 detects edges on a phantom image simulating a large vessel
- example4 detect edges on medical images of aortic regions
All the examples include parameters inside the code to play with. All the sample images are available online.
