The Morlet wavelet, as a representative complex wavelet, has a frequency-domain response that exists only on the positive-frequency side, its phase and amplitude information is fully preserved, and no cross-term interference is introduced in energy computation, so the scalogram exhibits a smooth envelope.

UnverifiedComplex wavelets (such as Morlet and dual-tree complex wavelets) provide approximate shift invariance, and their phase information can be used for precise instantaneous frequency and phase analysis.75% similarUnverified根据衍射极限公式，光束发散角与波长成正比、与发射口径成反比69% similarUnverifiedApplying the Hilbert transform to the real wavelet transform coefficients scale by scale approximately yields analytic wavelet coefficients, from which the instantaneous amplitude and phase can then be extracted.67% similarUnverifiedHyperspectral imaging collects data over hundreds of contiguous narrow bands, a single data cube is far larger in volume than an ordinary RGB image, and adjacent bands are highly correlated; in real scenarios there is no noise-free hyperspectral reference, so supervision signals can usually only be constructed by synthetic noise or physical simulation.62% similar
