如何从录像中轻率地描绘出简便的图像和短视图像?
原标题:How to easily unshift and RGB image captured from a video recording?

我正在寻找一种简单的修复图像的方法,这种图像确实造成了对罗姆人的转变的扭曲。

我不知道这是否重要,但歪曲源自用一张捕获卡记录录像信号。

第二种图像是通过制造子纤维而获得的;128 等于0 和 ;128 至255。

象蓝色频道一样,红树和绿线的左侧被冲抵1皮克:

“blue

如果你对此表示正确,并用积极的伽马纠正办法改成灰色,那么你最终将做这样的事情:

corrected

我并不认为你需要担心真正的怀疑性格勃转变为灰色转变,因为这一来源材料是独一无二的。 换言之,所有渠道都可以得到同等的重视。

问题回答

鉴于你想要获得最高地位,我建议的是,你只是把形象变成黑色和黑色;在行使最高地位之前,就把形象变成白人。

我用于这一转换的方法是首先将每种微粒转换成光线,使用这一公式:

P = 0.2989 * R + 0.5870 * G + 0.1140 * B 

然后,作为第一次尝试,如果P >=128或黑色,则将加工图像中的子.印成白色。

根据试验,你可能发现,在光线中将黑人和白人混血相分离并非最佳,因此你可以改变。 例如,如果你的B&W图象传播得太多,你可能希望通过提高门槛(即:尝试P>=160而不是P>=128),向白人发送更少的颜料。 反之,如果B&W图画失去许多细节,你可能需要降低门槛,让更多的人去做白人。

我希望这一帮助。
