Code works but obviously you do not have a valid colormap as imresize function try to tell you.

Hi, I tried them and I have a few question. I zeropad the matrix to have it square, i hope that's not a problem. the itv give me "Nan" matrix, I don't get anything. do you know why?

with the atv, it's doing around 7 iterations, but at the end, when I subtract the resulting matrix with the original one, I have only zero...
Do you know why too ?

thanks !

niu, can you just zero-pad your image?

hi,i met the saem problem as bmw. And i found it because the parameter N in function DiffOper() must be equals to image size squared. The width and length of your example image 'Lena512.png' just the same,i.e.512. So it runs correctly. But when the width and length is not equal, the function spdiags() in DiffOper() will give the wrong instructions, which is just like the problem mentioned by bmv. Can you give me some suggestions how to solve this problems? or pherhaps you can remedy this bug?
Thanks!
