Medical Image Segmentation using Active Contours
Running the Program
-------------------
To avoid calling the active contour methods directly, simply type:
> segmentscript
at the matlab prompt. This script will ask the user to select an image,
the amount to scale the image by, and the method of segmentation. Be careful
when selecting the edge-stopping approach to segment data as it can take a
very long time for even medium size images. To play around with parameters
for the edge-stopping approach, change the 'EPSILON' variable in the
calcspeed.m file. To adjust parameters for the active contour without edges
approach, change the 'mu' variable in the activecontour.m file.
As the segmentation proceeds, the current iteration number will be displayed
in the console. The current segmented image is displayed and saved to disk
every 100 iterations.
