GPU Implementations

SAD: each thread computes SAD between kernel and the 4 windows in its Macro Block
2D Convolution: like SAD, but with multiply-accumulate
2D FFT Convolution: used CUFFT to implement frequency domain version
Correntropy: adds Gaussian lookup table to SAD, computes max values in parallel post processing
