MATLAB Programming/Image Processing Toolbox - Wikibooks, open books for an open world A note on color space conversions [edit] Note that when converting from device-specific color spaces like RGB to non-device-specific spaces like LAB or XYZ, some inaccuracy will inevitably arise. One reason for this is that RGB values as given by MATLAB a
MATLAB Central - Steve on Image Processing » Plotting the DTFT using the output of fft In my Fourier transform series I've been trying to address some of the common points of confusion surrounding this topic. For today's espisode I want to look at how to use the fft function to produce discrete-time Fourier transform (DTFT) magnitude plots
