WebApr 18, 2012 · The simplest way to think about it is that the Optical Transfer Function is the Fourier transform of the point-spreading function (PSF). Usually PSF is a filter (convolution kernel) that describes how a single pin-hole type light source would get smeared into an actual image via some device. The OTF is just the amplitude/phase representation of ... WebOct 23, 2024 · psf2otf_Dy_GPU.m . View code README.md. Real-time Image Smoothing via Iterative Least Squares.
