do covered that ah how to use the discrete wavelet transform in images and then we had also planned to cover that how the dwt coefficients are actually encoded in order to generate the bit stream now ah we could not exactly cover to the extent we had desired in the last class because of ah some shortage of time so we are going to continue with that in this lecture and the title that we have for this lecture is embedded zero tree wavelet encoding now towards the end of the last lecture i had actually introduced to you the concept of the parent child relationship that exists between the coefficients in the different sub bands all right and especially we had seen that whenever we are changing from one resolution to the next okay to the to the more final resolutions whenever we are going there we are finding that ah one pixel or one coefficient in the ah coarser resolution or coarser scale that corresponds to four ah coefficients in the next final level of scale ok and this is what will fo

What is code working?

Code works by instructing the computer on how to process data it receives as input (such as from the user of the program, or a database with relevant information) and then outputting the results in some way, such as displaying them on the screen.

What is EZW in Matlab?

Image compression algorithms based on Discrete Wavelet Transform (DWT),such as Embedded Zero Wavelet (EZW) which produces excellent compression performance, both in terms of statistical peak signal to noise ratio (PSNR) and subjective human perception of the reconstructed image.

What is %# function Pragma in MATLAB?

The %#function pragma informs MATLAB Compiler that the specified function(s) will be called through an feval , eval ,Handle Graphics callback, or objects loaded from MAT-files.

What is the Euler number in MATLAB?

Tips. For the value e = 2.71828, called Eulers number, use exp(1) to return the double-precision representation. For the exact representation of Eulers number e, call exp(sym(1)) . For the other meaning of Eulers numbers and for Eulers polynomials, see euler .

What is the e function in MATLAB?

In MATLAB the function exp(x) gives the value of the exponential function ex. Find the value of e. e = e1 = exp(1). MATLAB does not use the symbol e for the mathematical constant e = 2.718281828459046.

What is the Zerotree of wavelet coefficients?

The zerotree is based on the hypothesis that if a wavelet coef- ficient at a coarse scale is indocHub with respect to a given threshold T, then all wavelet coefficients of the same orientation in the same spatial location at finer scales are likely to be indocHub with respect to T.

What is the EZW algorithm in MATLAB?

EZW combines stepwise thresholding and progressive quantization, focusing on the more efficient way to encode the image coefficients, in order to minimize the compression ratio. Two variants SPIHT and STW (see the following table) are refined versions of the seminal EZW algorithm.
