Sante FFT Imaging 1.4.1 | Size: 6.76 MB
Sante FFT Imaging is a program that removes pattern noise from DICOM and plain images (jpg, tif, png and bmp). This type of noise is very common in images that have been digitized with a CR digitizer. The program uses the Fast Fourier Transform (FFT), convolution low-pass filters in frequency domain or/and direct frequency deleting to eliminate the pattern noise.
The Fourier transform
The Fourier transform is a mathematical tool used to transfer an image from spatial domain to frequency domain. In the frequency domain we can view the power spectrum of the image, that indicates how much a frequency participates in the image construction.
