Franky..wrkin on it...
@John: The salt and pepper noise I've added has default zero mean noise with 0.01 variance. Hence the proposed median filter does the job well...inn case the variance is greater than 0.2...adaptivem median filter wud be the choice.

13 Mar 2014 Primitive Root Checks whether alpha is a primitive root of q or not. Author: Cavin Dsouza matt Mangani

13 Jan 2014 Chinese Remainder Theorem Computes CRT of a system of equations of the form x=r1mod(p1),x=r2mod(p2)........... Author: Cavin Dsouza Michael

I have found that the CRT function does not always compute the right answer. An example: With n=1401 and bases [15 16 17], CRT returns 1911. With n=1399 CRT returns 889 but with n=1400 CRT returns the correct value. With bases [17 18 19] CRT appears to work correctly, although I have not done any exhaustive checking.

02 Dec 2013 POWERMOD The function calculates A = powermod(base,exponent,modulus) Author: Cavin Dsouza John D'Errico

Note that my vpi toolbox does have a powermod tool that works for either vpi or double input.
