说明：  利用MATLAB实现图像前期预处理功能（包括彩色图像的灰度化变换等、一般灰度图像的二值化处理、色彩增强等），边缘检测，图像分割，图像特征提取等图像处理。
(Early use of MATLAB for image pre-processing functions (including color images of gray-scale transform, the general gray-scale binary image processing, color enhancement, etc.), edge detection, image segmentation, image feature extraction and other image processing.)
