Description: In this paper the analysis of the compression process was performed by comparing the compressed signal against the original signal. To do this the most powerful speech analysis and compression techniques such as Linear Predictive Coding (LPC) and Discrete Wavelet Transform (DWT) was implemented using MATLAB. Here nine samples of spoken words are collected from different speakers and are used for implementation. The results obtained from LPC were compared with other compression technique called Discrete Wavelet Transform. Finally the results were evaluated in terms of compressed ratio (CR), Peak signal-to-noise ratio (PSNR) and Normalized root-mean square error (NRMSE).The result shows that DWT performance was better for these samples than the LPC method.

Description: 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,

Description: 图像清晰度评价函数说明
1、熵: 表示图像所包含的平均信息量的多少,嫡值越大则所含信息量越多。
文件名：entropy.m 结果：EN
2、交叉嫡：反映两幅图像的差异,交叉嫡越小,则融合图像和原图像的差别越小。
文件名：cross_entropy.m 结果：平均交叉嫡MCE，均方根交叉嫡RCE
3、峰值信噪比: PSNR越高,说明融合效果与质量越好。
文件名：psnr.m 结果：PSNR
4、Qabf: 评价边缘或梯度质量，越大边缘越明显
文件名：Qabf.m 结果：Qabf（QAB/F)
5、平均梯度（Average Gradient）:也称为清晰度，反映了图像中的微小细节反差与纹理变化特征，同时也反映了图像的清晰度，越大越好。
文件名：avg_gradient 调用：outval = avg_gradient(img)
6、结构相似性指数： SSIM指原图像和融合图像的相似程度,值越大越相似
文件名：ssim.m 结果：SSIM
7、互信息：MI(mutual information)
8、NMI: Normalized mutual information(Image sharpness evaluation function)
