01 Dec 2008	Impulse Noise Addition Adding impulse noise to image Author: Kannan Keizer	Luengo, Cris	1st: you're using incorrect statistics when you change the output of RAND the way you do (setting 0 values to 1 and dividing by the max value). Just use the output of RAND directly in your comparisons, that is what RAND is designed for. 2nd: A function that asks to enter a choice every time it is run is inconsistent with all the other functions in MATLAB (and annoying), the choice should be an input parameter to the function. Also, you could provide default values for the ND and D parameters. 3rd: There is no need to output the result to a figure window. Let the user decide whether they want that or not.

27 Jun 2008	Color Filtering This function can be used for separating or segment Red components, Green components and Blue Compon Author: Kannan Keizer	D'Errico, John	A truly trivial operation, here performed using nested loops to do something that should be done with a single test on the entire array. This code lacks an H1 line. It has a single error check, that fails to trip over 3-d arrays that are clearly NOT RGB image arrays. What happens in this code if (size(img,3)==2)?
