# Edge Preserving Smoothing using Java

Posted on 2002-06-16

Hi,

I am trying to impliment the "mode", median" and "k-nearest neighbour" edge preserving smoothing filters in Java but I am just a beginner in Java. Would anybody be able to help me out with these??

Also, I want to write a Java program to do basic block truncation coding on a 256*256 image with 256 grey levels. I want to be able to store the 2 grey level values for each 4*4 block in two 64*64 arrays. Could anyone help me with this??

Finally, I want to write a Java program that will work on an image array with 16 grey levels to do the following:

-using an appropriate length natural code for the grey levels, and binary bit-plane coding, compute the total number of runs in each bit plane

-using an appropriate length Gray code for the grey levels, and binary bit-plane coding, compute the total number of runs in each bit plane.

I would really appreciate any help in this!

Regards,

Guster
