I can't see the image. If you use rgb2gray() you probably won't get anything that makes sense. You really need to have the color map that was used to pseudocolor the image. If you have that you can recover the original gray scale image using
grayImage = rgb2ind(rgbImage, colorMap);
Then you can threshold that grayscale image to get a binary image. By the way, your image link is broken.

I'm not sure what you mean, but see my attached freehand masking demo and see if that does what you want.
