dftcv
Computes the Discrete Fourier Transform of an image. dftcv is available only on Windows.
Syntax
R = dftcv(handle)
[R, data] = dftcv(handle)
Inputs
- handle
- Handle of an image.
Outputs
- R
- Handle of the Discrete Fourier Transform image.
- data
- Discrete Fourier Transform data of the image.
Example
Apply Discrete Fourier Transform on an image:
Figure 1. Input image
Figure 2. Filtered image
handle = imreadcv('image1.jpg');
[R, data] = dftcv(handle);
