图像处理中用到的一些代码，在MATLAB环境下开发的。(image segmentaion.)

关于端点检测的几种方法，语音样本是自己录制的，对传统算法做了一些改进，加入了去噪，去噪之后再进行端点检测，均调通 vad0303：自己设置调整门限为一定值 vad0310：根据能量值和过零率设置门限，自适应门限值 vad0310_2：基于比例因子的门限自调整 vad0310.m加入了噪声，端点检测前都噪声进行了处理 entropy.m：基于自适应子带频谱熵的稳健性语音端点检测 可用于语音增强及端点检测 dbdoor.m：双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测(Several methods on endpoint detection, recording their own voice samples, the traditional algorithm has made some improvements, adding a de-noising, and then after de-noising endpoint detection are transferred through)

将浮点数和32位二进制相互转换。一共四个m文件，三个函数：小数点转二进制，浮点数转二进制，二进制转浮点；最后一个：调用函数。 希望能帮到有需要的人( floating point Numbers and 32-bit binary conversion to each other. four m file, three functions: decimal to binary, float to binary, binary to float The last one: the calling function. hope this can help people in need)
