You can decompose a picture into (2D) sine waves. In fact, a time series signal is also "static" in the sense that in offline analyses, you have the whole signal and all of its time points. Maybe it helps to think about a picture of a rock dropped into a still lake -- that rock will produce ripples in the water, and you can represent those ripples using spatial sine waves.
Goat! Best description of this material I've come across.
Thank you, kind internet stranger.
Greetings and thanks for sharing Mike. Simple, clear and very well explained and God bless Matlab! :-)
So good. Thank you for posting.
what is there for frequency role in image algorithm ,i couldnt understand that
Hey, what does the frequency and amplitude of a static picture mean? I only understand these terms with respect to waves.
