Wavelets: Frequency Analysis
Building the Cantata Workspace
- Get image gull.viff, display it, take a one-level forward wavelet
transform, determine its spectrum and display the results.
Use the operators
User defined,
Display Image,
FFT,
and
Wavelet Transform.
- Extract the four quadrants of the wavelet transform, find the
spectrum of each and display the results. Use the operators
Extract and
FFT,
and
Display Image.
Exercises
- Perform the same experiment but with different images.
