Web8 de ene. de 2024 · Right now there is no option to set the color of the background that is exposed after rotation. You could make a copy of imrotate () and call it imrotateColor.m and then edit it to put in the color you want. Or you could rotate a uniform image and find the zero pixels and replace those in your actual image with the color you want.

What I am unsure of is how the FFT function is zero padding? I would like there to be an even number of zeros on each end of my data so that when I apply a window, my data are centered. Any help on this would be greatly appreciated.

WebThere’s a classic technique you need to be aware of when working with the Discrete Fourier Transform, and it’s called Zero-Padding. 1 As it turns out, it’s possible to interpolate or “fill-in” the output of the DFT by simply appending zeroes to the end of your input signal. Web2 de ene. de 2016 · You have to remember that with the DFT the time domain is also periodic, so the left side of the plot represents time t = 0 and the far right side represents time t &lt; 0. If you use fftshift the plot will look as you'd expect except that the middle of your plot will reresent time t = 0.
