Good question. There is nothing built into the Image Processing Toolbox that I'm aware of though I wish there were. You can look at this link posted by Helen at the Mathworks: http://www.mathworks.com/matlabcentral/linkexchange/links/2031-putting-pca-to-work
Or see if anything in the File Exchange will work for you: http://www.mathworks.com/matlabcentral/fileexchange/index?utf8=%E2%9C%93&term=pca
