wavelet

listen to the pronunciation of wavelet
English - Turkish
English - English
A fast-decaying oscillation
A small wave; a ripple
a ripple
A mathematical function useful in digital signal processing and image compression In the Internet communications, wavelet has been used to compress images to a greater extent than is generally possible with other methods such as JPEG or MPEG More details
a function that "waves"; a set of wavelets creates a basis of a wavelet transform; we can distinguish a lot of kind of wavelets: Haar, Mortlet, Daubeshies, etc wavelets; they look different and they have different properties: can be orthogonal, bi-orthogonal, normalized etc
A waveform that is bounded in both frequency and duration Wavelet tranforms provide an alternative to more traditional Fourier transforms used for analysing waveforms
Spectral Analysis
{i} small wave, ripple
A little wave; a ripple
A seismic pulse usually consisting of 1-1/2 to 2 cycles
Wavelets are small waves on the surface of a sea or lake
A member of a family of functions generated by taking translations e g , w(t) w(t 1) and scalings e g , w(t) w(2t) of a function w(t), called the mother wavelet The choice of w(t) is limited by the condition that the square of w(t) be integrable over all t Linear combinations of wavelets are used to represent wavelike signals The wavelet decomposition of a signal offers an advantage over the Fourier decomposition in that local or short-term contributions to the signal can be better represented
a small wave on the surface of a liquid
