Description: 1. The spectral function of the computed image
Design image: 120*30/256* 256; Use Matlab function to call the implementation directly.
The properties of Fourier transform are proved by calculation
1. Conjugate symmetry:
F (u, v) = F * (- u, v);
3. Frequency domain filtering of images
1. Design an exponential low-pass filter with two images (f1 (x,y) as 30*30/256* 256. F2 (x,y)=p3-02 image) to conduct low pass filtering to observe the change of spatial image and spectral distribution.
4. Comparison of image transformation
Using the existing discrete Fourier transform, discrete cosine transform and Walsh-Hadamard transform to transform the same image, compare the spectrum obtained by three kinds of transformations.
