Say that I have an image where there are some pixels which values are negative. How can I omit those from the image representation in `MATLAB`?
Thanks.

What's going on? You already had a discussion on this going in http://www.mathworks.com/matlabcentral/answers/116236#comment_196593 and then you posted the same thing twice more. I deleted the version that no one has answered yet. Why would you want to look for answers in three separate threads?????

Depending on your data and application, you can just take the absolute value. If that doesn't work you can set all the negative values to zero using logical indexing
X = randn(256);
X(X<0) = 0;
