While drawing the initial contour follow the messages in the command window.
At load time (whether from image or .mat file) keep scale depth at 0 if you want to start at the finest resolution. (I suspect you load a ~72x72 array and have kmax set at 3?)
Will look into adding capability to load an initial contour. What is in there already is the ability to save the level-set function and re-use it. (Say once you have input a complicated initialization, you don't want to go through it every time, so you can save it and load it over. However, the image data has to be of the same size.
thanks for sharing the code. I'm having troubles to create a manual initial contour. I select the option Ini. Method "draw" and then I press the button "DO Iter!" but I can't select points with the mouse. What am I doing wrong?
Another question: If I have already the initial contour as a binary mask, can I avoid the function "iniMembrane"?
Thank you very much
For starters, there is a very short description under Help | Buttons.
You can try the Chan-Vese paper I referenced higher in the abstract (no. )
The normalization you mention is done precisely in order to decouple the parameters value from the actual image values (which could come as uint8, uint16, 0-1, or any other data).
