The Application of Linear Systems Analysis to Image Processing. Some Notes. Horn, Berthold K.P.; Sjoberg, Robert W. The Fourier transform is a convenient tool for analyzing the performance of an image-forming system, but must be treated with caution. One of its major uses is turning convolutions into products. It is also used to transform a problem that is more naturally thought of in terms of frequency than time or space. We define the point-spread function and modulation transfer function i...
