拉普拉斯算子，检测图像的边缘纹理等细节信息，然后以适当比例线性叠加原始图像和细节信息，从而完成图像的增强-Laplace operator, the edge detection image texture details, etc., and then an appropriate proportion to the linear superposition of the original image and detail infor

lapla图像增强，可用于图像的增强处理，以有利于后期的特征提取等应用-lapla image enhancement, can be used for image enhancement in order to facilitate the later feature extraction applications
