本次作业是在matlab环境中实现的，主要运用了图像处理的基础知识对一张车牌图像进行预处理。如图像转换、图像形态学处理以及图像的边缘检测等来增强图像的对比度。在此基础上利用形态学方法以及投影法相结合来定位图片中的车牌，并将其从图片中剪切出来。最后，将提取出来的车牌字符分割成单个字符并组成新的图像。(This work is implemented in matlab environment, the main use of the basics of image processing on a plate image preprocessing. The image conversion, image processing, and morphological image edge detection or the like to enhance the contrast of the image. Morphology and projection Combination plates to locate the picture, and cut out the picture on the basis of use. Finally, the extracted license plate character segmentation into individual character and form a new image.)

说明：  针对低信噪比环境下基于能零比的端点检测方法准确率低的问题,提出了一种结合谱减法和短时零熵法的端点检测方法。首先通过功率谱减法对带噪语音进行降噪处理,然后结合短时平均过零率特征与谱熵特征,构造出一种新的语音参数,即短时零熵,最后运用双门限算法进行端点检测。实验结果表明该方法在复杂噪声环境下具有良好的端点检测性能,降低了检测的误判率。(To solve the problem of low accuracy of endpoint detection method based on energy zero ratio in low SNR environment, an endpoint detection method combining spectral subtraction and Short-term zero entropy method is proposed. Firstly, the noise is reduced by power spectrum subtraction, then a new speech parameter, short-time zero entropy, is constructed by combining the short-time average zero crossing rate and spectral entropy. Finally, the double threshold algorithm is used for endpoint detection. The experimental results show that this method has good performance of endpoint detection in complex noise environment, and reduces the rate of detection error.)
