Version 3.5 of the Imaging Whiteboard introduces extended frequency domain processing. The FFT control will now output the FFT results with the output image, a second FFT control will detect the previous results and perform the reverse FFT. Other controls have been extended to support processing these results.
Here an image of Jane Russell has been transformed and the high frequencies excluded. An image of Tony Curtis has been transformed and the low frequencies excluded. The two processed FFT results have been added and the reverse transform performed. When the image is viewed close up the eye sees Tony, from a distance the eye sees Jane.
