Subvoxel Edge Detection
This is the Matlab source code of the subvoxel edge detection method, as an extended version of the
original method described in the paper “Accurate Subpixel Edge Location Based on Partial Area Effect”,
published by Elsevier in http://www.sciencedirect.com/science/article/pii/S0262885612001850
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.
