Matlab is perfect tool to process digital imgae.This .rar file includes many .m files with detailed comment.They can complete many operations of DIP.

In matlab, after creating the figure you need to save it as a pdf format for various of purposes. in this function I illustrated how you can save your figure in pdf format,

this is matlab code for noise estimation
