Create mask from bwtraceboundary in Matlab. image,matlab,image-processing,mask,boundary. It's very simple. I actually wouldn't use the code above and use the image processing toolbox instead. There's a built-in function to remove any white pixels that touch the border of the image. Use the imclearborder function.
The 2D Fourier Transform is an indispensable tool in many fields, including image processing, radar, optics and machine vision. In image processing, the 2D Fourier Transform allows one to see the frequency spectrum of the data in both dimensions and lets one visualize filtering operations more easily.
Fourier[list] finds the discrete Fourier transform of a list of complex numbers. Fourier[list, {p1, p2, ...}] returns the specified positions of the discrete Fourier transform.
I am trying to do homomorphic filter for a gray scale image. I have pixel information in an int array which will be the input for below: ln -> FFT -> filter () -> IFFT -> exp For the FFT/IFFT portion i can do the C2C transform vs R2C right? Provided I prep the data by copying the pixel info into the complex array as below? Complex *h_signal = (Complex *)malloc(sizeof(Complex) * SIGNAL_SIZE ...
