Lifting Wavelet Transform of Integer-Valued Signal Copy Code Copy Command Specify an integer-valued signal. Create a lifting scheme associated with the db2 wavelet. Get sig = 1:10; lsc = liftingScheme('Wavelet','db2'); Obtain the level 2 lifting wavelet transform (LWT) using the lifting ...
Analysis of Image Compression Methods using DCT and Wavelet Transform in MatlabImage compression reduces the amount of data required to represent an image. To compress an image efficiently we use various techniques to decrease the space and to increase the efficiency of transfer of the images over ...

CWT as a Windowed Transform InShort-Time Fourier Transform, the STFT is described as a windowing of the signal to create a local frequency analysis. A shortcoming of the STFT approach is that the window size is constant. There is a trade off in the choice of window size. A longer time ...
