4. an object detection method with em ( expectation maximum ) algorithm of dynamic layer representations is researched and improved. previous algorithm contains optical flow computation, affined transformation, and clustering algorithm, and it is not convenient for detecting object quickly
4 .分析並改進了基於em （ expectationmaximum ）演算法的運動目標分層檢測演算法，早期演算法由於涉及光流場求解、仿射變換、聚類合併等復雜運算，計算量大，不適合圖像序列的快速處理。 -
This article firstly deal with the sound source, noise measurement and analysis, noise control principle and some basic noise control technology, then elaborate the current noise detection standard and method for the coach in our country, the noise mechanism. characteristics and the measures of noise - controlling, finally. describe the actions of noise control, noise detection and optimization in our coach detailedly, which have met with the expectation
本文首先敘述了聲音的產生原因、噪聲的度量和分析方法；介紹了噪聲的控制原理和原則以及一些基本的噪聲控制方法。然後，介紹了我國目前的客車車內噪聲的檢測標準和方法；詳細闡述了客車主要噪聲源的產生機理和噪聲特性以及車內噪聲控制措施；最後，理論與實際相結合，對我公司的lck6122型大型客車採取了相應的噪聲控制措施以及並其進行了測試和優化。
