Super Resolution ================ .. highlight:: cpp The Super Resolution module contains a set of functions and classes that can be used to solve the problem of resolution enhancement. There are a few methods implemented, most of them are descibed in the papers [Farsiu03]_ and [Mitzel09]_. superres::SuperResolution ------------------------- Base class for Super Resolution algorithms. .. ocv:class:: superres::SuperResolution : public Algorithm, public superres::FrameSource The class is only used to define the common interface for the whole family of Super Resolution algorithms. superres::SuperResolution::setInput ----------------------------------- Set input frame source for Super Resolution algorithm. .. ocv:function:: void superres::SuperResolution::setInput(const Ptr<FrameSource>& frameSource) :param frameSource: Input frame source superres::SuperResolution::nextFrame ------------------------------------ Process next frame from input and return output result. .. ocv:function:: void superres::SuperResolution::nextFrame(OutputArray frame) :param frame: Output result superres::SuperResolution::collectGarbage ----------------------------------------- Clear all inner buffers. .. ocv:function:: void superres::SuperResolution::collectGarbage() superres::createSuperResolution_BTVL1 ------------------------------------- Create Bilateral TV-L1 Super Resolution. .. ocv:function:: Ptr<SuperResolution> superres::createSuperResolution_BTVL1() .. ocv:function:: Ptr<SuperResolution> superres::createSuperResolution_BTVL1_GPU() This class implements Super Resolution algorithm described in the papers [Farsiu03]_ and [Mitzel09]_ . 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<DenseOpticalFlowExt> opticalFlow** Dense optical flow algorithm. ..
