Abstract—In this paper, a new lossy technique based on wavelet
transform for compression of breast ultrasound images is
presented. The experiments are performed on 16 different
wavelet functions and the quality of reconstructed images is
evaluated by using Compression Ratio (CR), Normalized Mean
Square Error (NMSE), Normalized Absolute Error (NAE), and
Peak Signal to Noise Ratio (PSNR) criterion. An
ultrasonographer performed the subjective assessment. This
study shows that among the utilized wavelets,

fit_ML_normal
fit_ML_normal - Maximum Likelihood fit of the normal distribution of i.i.d. samples!.
Given the samples of a normal distribution, the PDF parameter is found
fits data to the probability of the form:
p(r) = sqrt(1/2/pi/sig^2)*exp(-((r-u)^2)/(2*sig^2))
with parameters: u,sig^2
format: result = fit_ML_normal( x,hAx )
input: x - vector, samples with normal distribution to be parameterized
hAx - handle of an axis, on which the fitted distribution is plotted
if h is given empty, a figure is created.
output: result - structure with the fields
sig^2,u - fitted parameters
CRB_sig2,CRB_u - Cram?r-Rao Bound for the estimator value
RMS - RMS error of the estimation
type - ML
