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,

应用背景   信号是无限长的，而在进行信号处理时只能采用有限长信号，所以需要将信号“截断”。在信号处理中，“截断”被看成是用一个有限长的“窗口”看无限长的信号，或者从分析的角度是无限长的信号x(t)乘以有限长的窗函数w(t),由傅里叶变换性质可知    如果x(t)是频宽有限信号，而w(t)是频宽无限函数，截断后的信号也必是频宽无限信号，从而产生所谓的频谱泄露。 关键技术 用MATLAB编程绘制各种窗函数的形状  2、用MATLAB编程绘制各种窗函数的幅度响应  3、绘制矩形窗的幅频响应，窗长度分别为：N=10，N=20，N=50，N=100  4、已知周期信号x(t)=0.75+3.4cos2πft+2.7cos4πft+1.5sin3.5πft+2.5sin7πft，其中f=Hz，若截断时间长度分别为信号周期的0.9和1.1倍，试绘制和比较采用下面窗函数提取的x（
