The experimental results show that the forecasting algorithm with both wavelet transform and clustering has performed better. Besides, firefly algorithm-based SVR outperforms the other algorithms. However researcher have worked a lot with hybrid

Fourier transforming property of lenses - MIT …
ocw.mit.eduEach spherical wavelet is collimated by the lens and contributes to the output a plane wave, propagating at the appropriate angle (scaled by f.) On the right, the transparency is interpreted in the Fourier sense as a superposition of plane waves (“angular” or “spatial frequencies.”)
Distinctive Image Features from Scale-Invariant Keypoints
www.cs.ubc.caMarsic and Dickinson (1999) provides more distinctive feature descriptors using wavelet co-efficients. The problem of identifying an appropriate and co nsistent scale for feature detection has been studied in depth by Lindeberg (1993, 1994). He describes this as a problem of scale selection, and we make use of his results below.
