README ------ Info ---- Michael Wasilewski 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.
