P1*x*P2 is not a function.

I haven't used image(), but if I infer correclty, you'll need to first  
create your function

function y = yourfunction (x, P1, P2)
   y = P1*x*P2;
endfunction

It should be saved as yourfunction.m

Then call

blkproc(imag, [16, 16], @yourfunction, T, T')

I may not have everything exactly correct, but @yourfunction is a  
handle to "yourfuntion".
