Description
This plugin has 7 functions, it operates in frequency domain and requires the libfftw3f-3.dll from the FFTW library.
Often video images have three types of blur.
- 1. Blur due to relative movement of camera during the short time the shutter is open,
- 2. Blur due to subjects being out of focus
- 3. combination of both.
- 4. Regular frequency interference on images. These can be attenuated with either 1D or 2D frequency filters. Frequency spectral displays enable to find such interference and design correcting filters.
