data compression rate的意思|示意

The digital image has huge data information, so the algorithm which has high compression ratio and high fidelity rate is urgently needed, taking account of storage cost and communication.

由于数字图像具有数据量大的特点，出于对图像存储成本和图像通信的考虑，良好的图像压缩技术要能够实现高压缩率和高保真率。

The compare indicates this method is a low -complexity and high -coding -rate method among the current ECG data compression methods.

该方法是目前ECG信号压缩算法中计算量小、压缩比较高的一种方法。

The computation burden of the quadrature sampling and pulse compression is huge when the data rate is high and the time bandwidth product is not small.

在高数据采样率，特别是大时宽带宽积条件下，时域的数字正交采样和脉冲压缩包含大量的乘加运算。

The principal advantages of this approach are shift-invariant, high data compression rate, easy real-time implementation, using for invoking the shape filtering and shape measuring etc.

这种方法的主要优点是具有位移不变性、高数据压缩率、容易用硬件实时实现以及可以由物体形态谱表示精确地重构原始图像等。

Then, the principle of area exchange rate was used for image processing. After that, the data was kept and transmitted to the upper device by image compression algorithm of BP neural network.

然后采用面积换速度的原则进行图像处理，在图像处理过程中采用 BP网络图像压缩的算法保存并传输给上位机。

And if not using data correlation coefficient theory to determine whether there is defect in pipe, only using PSD particular frequency band storing method, the compression rate is extremely limited.

而如果没有数据相关度理论对数据进行预处理判断是否缺陷，功率谱特定频段数据保存法的压缩能力还是极其有限。
