图像空域增强处理
说明: 思想:把原始图的直方图变换为均匀分布的形式,这样就增加了灰度值的动态
范围从而达到增强图像整体对比度的效果。其优点是能自动地增强整个 图像的对比度。
1、对灰度图像进行直方图的均衡化处理,达到图像增强的目的。
2、利用平均滤波和中值滤波对图像进行平滑滤波。
3、利用拉普拉斯运算对图像进行锐化滤波。(Idea: transform the histogram of the original image into the form of uniform distribution, so as to increase the dynamic gray value
Range to enhance the overall contrast of the image. Its advantage is that it can automatically enhance the contrast of the whole image.
1. The gray image is processed by histogram equalization to achieve the purpose of image enhancement.
2. Average filter and median filter are used to smooth the image.
3. Using Laplace operation to sharpen the image.)
