but we dont have any specific data which is to be compared. we have to remove them with the help of their intesity or pixel value. for that there is an algorithm..check it out in my next post.

Well my point was how do you expect us to help you with such a vague description? I was trying to coerce more information out of you.

ok..see i m working on a project in which i have to detect brain tumor using segmentation with the help of neuro fuzzy technique. in this i have to read an image i.e mri. since it contains some artifacts means somthing written on the image.. so to remove it we use tracking algo... and that algo i have given in my post. can u help me in my project..?

To remove writing on all of the CT/MRI pictures I've looked at you just need a threshold. I've explained how to do that in the other thread. For more focused help you're going to have to share your image with us. Find some free file sharing site and post it, then provide us with the link.

The stated requirements of the project are unrealistic, at least in Canada,
the USA, and the European Union. Patient privacy protection laws in those
areas would prohibit personally identifying information from being present on
images being handled (processed) by anyone but the primary doctor.

My workplace actively researches detection of various brain abnormalities
(including tumors) on MRI data sets. Some of the data sets are obtained on
in-house machines, and some of them are obtained from associated hospitals
that we have research collaborations with. We have absolutely strict protocols
that the only identifying information that can be in an MRI dataset on any of
our computers is an arbitrary identifier, and that information is stored in
the header of the MRI data rather than on the image itself. We refuse to
accept MRI datasets or images from outside sources that have any personally
identifying information in them. We do not even allow our in-house people to
keep electronic spreadsheets that match personally identifying information
with the arbitrary identifiers: all such matching is required to be
hand-written in log books that are kept locked up.

There is NO chance that an MRI image that I receive for processing will
contain a patient name or age or the like written in to the image or even into
the dataset, and if I were to specifically ask for that information, I would
be firmly told that it is not legal here to provide that information to me.
