1,bilateral-filter(双边虑镜)
blur radius (模糊半径):
edge preservation (边缘保持):
原图
左侧是原图,右侧的是处理后的图。有些类似磨皮的效果。
2,box-blur (盒式模糊)
radius (半径) : (模糊半径),这里设置为4 效果如下:
3, brightness-contrast(亮度对比度)
contrast(对比度):
brightness(亮度):
效果如下:这里为了清晰的展示效果特意调成过暴的了。
4, c2g(彩色转灰色)
radius(半径):转换像素所影响映射的半径。影响结果精度。
samples(采样):采样数量影响颜色取值的范围。
iterations(迭代次数,即复重次数):更高的迭代次数,能加大计算成本,即会变慢。不过图片的质量也会有所提高。
5, checkerboard(棋盘)
