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 ... Web图像去模糊psf2otf. 课程目录. 相关资源. 课程笔记. 课时1：图像代数运算imsubtract. 课时2：图像代数运算immultiply. 课时3：图像代数运算imdivide. 课时4：图像代数运 …
