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_CUDA()
|
||
|
||
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.
