求矩阵腐蚀，膨胀的算法，以及梯度、平滑和高帽变换运算。-Matrix erosion, dilation of the algorithm, and the gradient, smoothing and hat transformation operations.

基于matlab的高帽变换，能很好地对图像进行一定的处理，实现图像的增强，线性特征的提取，为后续的处理做准备-Matlab-based top-hat transform good image processing, image enhancement, linear feature extraction, to prepare for subsequent processing
