Create Bilateral TV-L1 Super Resolution.

This class implements Super Resolution algorithm described in the papers [95] and [219] .

Here are important members of the class that control the algorithm, which you can set after constructing the class instance:

int scale Scale factor.
int iterations Iteration count.
double tau Asymptotic value of steepest descent method.
double lambda Weight parameter to balance data term and smoothness term.
double alpha Parameter of spacial distribution in Bilateral-TV.
int btvKernelSize Kernel size of Bilateral-TV filter.
int blurKernelSize Gaussian blur kernel size.
double blurSigma Gaussian blur sigma.
int temporalAreaRadius Radius of the temporal search area.
Ptr opticalFlow Dense optical flow algorithm.
