I have a problem with log while implementing vague shadow mask but the R component is already in uint8.

r=log®; Undefined function 'log' for input arguments of type 'uint8'.

Hi,
you need to convert back to double:
r = log(double(r));
If you afterwards go back to uint8 (which probably makes little sense), then use uint8 to convert.
