discrete data

基本解釋

This paper briefly introduces the mathematical processing of ARM used in power spectral analysis of discrete time-histories data and confirms the usalitity of ARM in earthquake engineering.
本文扼要敘述了用於離散時(shí)程數(shù)據(jù)的功率譜分析的自相關(guān)廻歸法（ARM）的數(shù)學(xué)過程。
The paper introduces an effective weighed- median filter and wave- let analysis filtering based on the discrete data dots- clouds of reverse engineering of the rapid prototyping manufacturing.
針對基於快速原型制造的逆曏工程散亂數(shù)據(jù)點(diǎn)雲(yún)，提出了一種先加權(quán)中值濾波，再小波分析濾波的新降噪方法。
This paper introduces how to use DCT(discrete-cosine transform)in data-hiding technology in image, and its fundamental theory and algorithms, special improvements of existing algorithms.
該文主要介紹了如何利用離散餘弦變換（DCT）實(shí)現(xiàn)對於圖象文件的數(shù)據(jù)隱藏技術(shù)，詳細(xì)說明了該技術(shù)的基本原理和實(shí)現(xiàn)方法，以及對現(xiàn)有算法的改進(jìn)。

Naturally, the usefulness of the slicing and dicing of data depends on the availability of contextual information, even for a discrete current event like a 90-minute debate.
