Hi all,

I have a series of MRI images, some of which display intensity inhomogeneities and suffer from the presence of a bias field. I have read several papers which have used splines to recover the bias field and correct the image.

I am aware that MATLAB has a splines toolbox but I am relatively new to the program and cannot find a function that i can input my raw image matrix and get a corrected image as output (or am I being too optimistic).

An example image can be seen here http://www.flickr.com/photos/10523358(a)N02/3886964001/

I would like to apply global thresholding to the image and so need to correct for these inhomogeneities.

Thanks in advance for any help
