图象的增强：包括灰度修正，模板操作，图象平滑，中值滤波，图象锐化，伪彩色假彩色增强-Image enhancement: include gray-level correction, template operations, image smoothing, median filtering, image sharpening, color enhancement false pseudo-color

实现图像增强,图像平滑,中值滤波,梯度锐化,拉普拉斯锐化,伪彩色编码-To achieve image enhancement, image smoothing, median filtering, sharpening the gradient, Laplacian sharpening, pseudo-color coding

伪彩色增强，通过密度分割法将灰度图像转换为彩色图像-Pseudo-color enhancement, through the density of gray image segmentation method to convert color images
