Unique Positive FM-AM Decomposition of Signals,An analytic signal, observed over an interval of . seconds, is decomposed into a Minimum Phase (AM) and an All-Phase (FM) signal. The former’s log-envelope and phase form a Hilbert transform pair while the latter has positive definite instantaneous frequency (IF). An AM-FM demodulator algorithm to achieve the above decomposition is proposed.作者: covert 時(shí)間: 2025-3-22 16:05 作者: 山崩 時(shí)間: 2025-3-22 21:00 作者: Gullible 時(shí)間: 2025-3-22 23:50

Optimal Reconstruction of Natural Images by Small Sets of Gabor Filters,optimal reconstruction are examined. At first, the search is performed on a 1-D signal which satisfies the radial spectrum of the average of natural images. Later, these results are extended and applied to a 2-D example. It is shown that the resulting parameters are better than those of some existing models.作者: brassy 時(shí)間: 2025-3-23 08:11

On the Computation of Optical Flow using the 3-D Gabor Transform,ferent motions cannot be resolved in the Fourier domain, nor associated with their respective regions in the image sequence.
