彩色图像处理,主要包括：灰度化，伪彩色，单色处理，霓虹，浮雕，滤波（低通，高通）处理等-color image processing, including : gray, pseudo-color, monochrome, neon, relief, filtering (low pass, Qualcomm) processing

用中值滤波器去除椒盐噪声,首先将彩色图像转换为灰度图像,然后利用中值滤波器进行滤波-Median filter to remove salt and pepper noise

将彩色图像以RGB分为三层，使用直方图对其对比度进行调整，产生预定义的滤波器对图像进行滤波，最后实现图像的增强-RGB color image is divided into three layers, using the histogram to adjust its contrast, produce predefined filters for image filtering, image enhancement and finally realize
