当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

说明：  用matlab编的Capon算法和延迟相加法的程序，能够实现不同信号入射时的DOA估计，从而可以比较两种算法的分辨率等(Used for the Capon algorithm matlab and delays add up to the law of procedure, to achieve different signal DOA estimates at the time of the incident, which can compare the two algorithms, such as the resolution)

This work introduces two variants of unsupervised color segmentation methods. The underlying idea is to segment the input image several times, each time focussing on a different salient part of the image and to subsequently merge all obtained results into one composite segmentation. As a first step salient parts have to be identified in the image, which is done by a simple local color clustering approach.
