第二代小波及压缩算法在数据处理中的应用

为消除误差和随机干扰对测量数据的影响,提出利用第二代小波提升算法对原始测量数据进行去噪处理,再利用基于第二代小波原理的数据压缩算法对测量数据进行不失真压缩。两种方法结合运用,可以在保留数据特征及精度的基础上,降低数据量,提高工作的速度和质量。

Application of Second Generation Wavelet and Compression Algorithm in Data Processing

To eliminate the error and random interference in measurement data.Presents using second generation wavelet lifting algorithm to make denoising process on raw measurement data,and makes non-lossless compression on the measured data by using data compression algorithm based on second generation wavelets principle.The combination of two methods,can reduce the amout of data,improve the speed and quality and retain the data characteristics and accuracy at the same time.
