Read the introductory sections in the
MATLAB user guide regarding file I/O and displays. Familiarise
yourself with the MATLAB "HELP" facility.
Run the matlab "demos" and select the "Region Labelling of Steel Grains"
deomo from the "Image Processing" toolbox. Run through the sequence of processing
steps provided making sure that you understand the algorithms being used at each stage.
Now run the "noise reduction filtering" demo. Apply the available image
noise and then observe the effects of the noise reduction algorithms.
Try to find out;
What is the best filter for "gaussian" random noise?
What is the best filter for "salt and pepper"(ie:"drop-out")?
In the context of our terminology, how would you describe
