A further step forward came with "the Polar Express" (2004), directed by Robert Zemeckis, the first entirely computer-generated film to use facial capture.
A set of camera demarcation scheme was brought forward to capture the clear image in nature circumstance and improve the robust character of capturing full vehicle image in random for VNPRS.
In the light of these characteristics, the paper deduces the cyclic spectrum of UQPSK, and puts forward an algorithm for carrier-frequency capture based on cyclostationarity.
