for(i=1:length(pv))
  a=pv(i);
  a=find(chars==a);
  a=pattern(0,1);
  num(8)=bin2dec(a);
end

I have no idea what you're doing. It looks like just a bunch of random lines of code - total nonsense. Explain what you want to do better. Do you have a gray scale image (uint8 or uint16) or a binary image (logical, true or false)? A gray scale image is already in decimal - that's that the gray levels are. And of course gray scale numbers. even though they are in the range 0-255 decimal, can be considered as binary just like any number can be considered as binary - not as true/false but as if you wrote the number out in 0s and 1 like you get by calling dec2bin(). A binary (true/false) image could be converted to a decimal image of values 0 and 1 if you want. I'm not sure what else to say until you explain better.
