Image compression is a method through which we can reduce the storage space of images which will helpful to increase storage and transmission process's performance. In this paper, we present the comparison of th
These methodologies will give the optimal utilization of hardware resources in the computation of Discrete Wavelet Transform (DWT). Moreover, quantization of DWT coefficients to a precise target step size. It is performed as an inbuilt part of the DWT computation, so eliminating the need to have...

Obtain the maximal overlap discrete wavelet transform down to the maximum level. Get w = modwt(Espiga3); Reconstruct the multichannel signal. Plot the original data and reconstruction. Get xrec = imodwt(w); subplot(2,1,1) plot(Espiga3) title('Original Data') subplot(2,1,2) plot(x...
w = modwt(x) returns the maximal overlap discrete wavelet transform (MODWT) of x. x can be a real- or complex-valued vector or matrix. If x is a matrix, modwt operates on the columns of x. modwt computes the wavelet transform down to level floor(log2(length(x))) if x is a vect...
