Livewire (Intelligent Scissors) ROI Creation



02 Apr 2013 (Updated )

Implementation of the livewire algorithm for intelligent ROI drawing. Can be used instead of ROIPOLY

File Information


Interactive GUI for drawing regions of interest (ROIs). Has a similar interface to ROIPOLY. However, the delineation of complex and irregular objects is supported by the livewire or intelligent scissors algorithm [1]: Instead of connection user-selected anchor points with straight lines, a minimum cost path is chosen. Low costs can be found along image gradients (potential object boundaries).

*** IMPORTANT NOTE ***: Make sure you run the mex compilation script "please_mex_me.m" once you downloaded the submission. Livewire will work without the mexed file, however (as you might imagine) with poor performance.

Have fun, please provide feedback.

thanks for the great program. But after i plant seeds (or anchors), the output is the background. What should I do to get the extracted part?
