DeFreq 0.7

DeFreq 0.7 Description:

DeFreq was designed to be a filter that can remove some interfering frequencies from video frames.

It can be used for removal of regular vertical, horizontal or inclined stripes from some analog TV captures without any image quality decreasing.

DeFreq uses Fast Fourier Transform method for frequency selecting and removing.

It is a spatial filter, and works as a follows:
- get frequency spectrum by forward FFT transform of frame image;
- search some defined spectrum window (windows) for local peak (maximum, extremum, most intense frequency);
- remove from spectrum a frequency at this sharp peak and some similar by amplitude neighbors in search window;
- optional remove highest frequencies by low pass Butterworth filter (for blurring, smoothing);
- get output frame by inverse FFT transform of cleaned spectrum.
