Interface Propagation and Isolating Shapes in Images:

Java Script for Medical Image Segmentation


The main idea here is to isolate and extract individual components from a medical image. This is an important part of medical imaging; once a shape is found, physicians can measure various quantities, such as the size of tumors and the thickness of heart walls. Tracing the boundary of these shapes by hand is time-consuming. Instead, the goal is an automatic segementation technique which finds the desired regions automatically. This can be done using a combination of fast marching methods and level set methods.


Instructions:

  1. Move the mouse into a region and click
  2. The Java script executes the Fast Marching Method to segment the desired region.
  3. Things to try:
