I am trying to compute the phase angle from the set of sequential images by using the concept of Fourier transform or Wavelet transform in MATLAB. I have about 100 images in sequence. Could somebody guide me or send the codes to find the phase angle?
if you have a sequences you have a 3-D matriz X·Y·N, when X and Y are the image size and N is the number of images. For what dimension, do you want to calculate the phase angle?
Dear Professor,
Thank you very much for your response. The size of image is 640*480 and the number of images is around 100.
Hope to hear you soon.
With regards,
%B is 3D-matrix (640x480x100)
tam=size(B);
FFT = fft(B,tam(3),3); % FFT for Number images (dimension 3)
mod=abs(FFT);
phase=angle(FFT);
figure;
plot(squeeze(phase(100,100,:))); %%Show the phase for the pixel (100,100)
Dear Professor Madruga,
Thank you very much for the codes. It works well for the assigned pixel and shows the phase angle information of all the input images (100 images in this case). However, is there any way to compute the single phase image of all the input images (100 images in this case) so that phase angle information can be compared with every pixel ?
