Hello,
I've been looking for a good algorithm to segment lungs from CT images. I have a serie of CT images (DICOM) from a phantom and I only want to segment the lung tissue. So far I've tried the "activecontour" function with the Chan-Vese algorithm (which is the default of the function), but it doesn't work really well: this function segments structures that aren't related to the lungs. When I've applied the function to a JPEG image, though, it worked. I don't know what to do; I'm new on MatLab and it's supposed to be a simple problem because I don't want to segment any structure, only the contour of the lungs.
Please, contact me if you can help me. I've tried many different algorithms and could not find a good one.
