% 5 patterns for TPWM algorithm (608*684 pixel resolution for DLP 
% Light Crafter). What should be explained is that in the process 
% of projection, only binary patterns are projected and the 
% exposure time of the camera is double of projection time so that % the more gray patterns can be obtained. Illumination of this 
% process is presented in the PPT.
