kDenoiseWavelet is the "k" in a wavelet filter. A wavelet filter does a scaling and rotation, before filtering the coefficients. This macro defines the "k" used in the filter.
If defined, this macro is passed to DefineGlobalMacro(FILTER_MODEL_DESC, "kDenoise", "kDenoise"). It needs to be defined before calling the filter. So for example, a new WaveletFilter, that uses a function of the macro would be written like this:
void WaveletDenoise(const Wavelet *w, int level, DenoiseParameters *params)
{
// calculate the coefficient for the wavelet.
}
// define the global macro
#define FILTER_MODEL_DESC { "kDenoise", "kDenoise" }
#define kDenoiseWavelet (-1)
// use the macro
WaveletDenoise(w, level, params);
I am looking for a potential problem. My input video is in H.264 format, and I don't know if the denoising will work on it (because no wavelet transform is done). But I can't use anything else for now, it has to be done with wavelets. And this is the only video format I have.
A:
Since the de-noising is done at the frame level, if your input is in H.264 format, this approach will produce a result that is not optimal for further processing (i.e. if you then apply further processing to remove the de-noising artifacts, you may end up with picture information that is no longer reliable due to the de-noising effect).
If you are using a video file with a different format, I suggest that you use a frame-level de-noising approach on it, instead.
I would recommend the "use cases" in the de-noising article by Mehrdad Dianati. The first one describes how you can implement such an approach with a custom C implementation (i.e. without using FFmpeg).
High-flow priapism: a case report.
In this report, we describe the successful management of a case of high-flow priapism. A 17-year-old man developed a painless erectile episode lasting for 6 hours. Subsequently, persistent priapism developed and was managed successfully by a blood transfusion. 4f8c9c8613 gionera
