David A Humphreys National Physical Laboratory davidhumphreysnplcouk Signal Processing Seminar 21 June 2006 Overview 149Introduction 149Prerequisites 149Convolution and correlation 1. Convolution op erates on two signals in 1D or two images in 2D you can think of one as the input signal or image and the other called the kernel as a 64257lter on the input image pro ducing an output image so convolution takes two images as input an Deconvolution is an indispensable tool in image processing and computer vision It commonly employs fast Fourier trans form FFT to simplify computation This operator however needs to t ransform from and to the frequency domain and loses spatial infor February 201 A Beginner’s Guide to Persistent IdentifiersVersion 1.0February 2011 Suggested citation: GBIF (201).
