文对静态图像的压缩方法作了较深入的研究，利用多分辨分析对图像进行分解，并利用小波的标量量化图像压缩编码算法对图像进行压缩，其间对原算法进行了研究和探讨；在上述理论工作的基础上，应用Matlab仿真实现了相应的算法。实验结果证明，基于小波的标量量化图像压缩编码算法是可行的和有效的。(A deep researeh on static image compression 15 presented in this paper. on the basis of theoretical work above，programming achieves corresponding algorithm. It’s proved that programming achieves corresponding algorithm image compression and image code.)

这是MATLAB中的三个很好的实验，通过这三个实验可以更好地理解数字图像处理的原理(This is the MATLAB three very good experiment, the adoption of these three experiments can be a better understanding of the principles of digital image processing)

当信噪比较大时，采用广义最小二乘法可能会出现多个局部收敛点，解决这个问题的方法可用多级最小二乘法，一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据，通过多级最小二乘法，可分别求的辅助模型，过程模型和噪声模型的参数估计值。在高噪声的情况下，多级最小二乘法明显优于广义最小二乘法，其收敛点唯一。(When the signal noise ratio (SNR), and by use of the generalized least squares method may appear more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)
