Multiple Sclerosis Lesion Segmentation

Dear friends I want to make feature vectors from local intensity regions in MR images. I use Twenty datasets from MS patients with FLAIR, T1,T2, data with expert annotations are available as training set from the MICCAI 2008 challenge on MS, and 24 test datasets. can you help me to extract feature vectors?

dear rahil I have a similar problem as yours now. I want to load images of MICCAI 2008 challenge in matlab and I do not know what to do. could you give me a hand? hope to hear from you soon

You probably won't hear from him since this was his only post and it was 4 years ago. To load images, use imread(). Also see The FAQ.

use ITK_SNAP

thanks for your answer, now I want to extract features from MR images, I have two questions 1- are there any ready code or toolbox for this purpose 2- which one features is better for segmentation? (texture, probability, histogram,intensity,...) thanks in advance

[Image Analyst]

1. I don't know of a toolbox that is specific to MRI images, though there is the general purpose Image Processing Toolbox.
2. You should contact the radiologist that you are partnering with for the answer to this. You can also look at section 20 of VisionBib

Thanks for your help, but when using imread as follows : fin=imread('unc9.raw'); I get this error "Unable to determine the file format. " how can I solve this error?
