[英]Are there any algorithm to make real photo more fake-like?
I know some ray-tracing algorithm can achieve very realistic photo 我知道一些光线跟踪算法可以实现非常逼真的照片
But,now I want to do make a fake-like photo out of a real photo 但是,现在我想用真实照片制作出伪造的照片
how can I do this? 我怎样才能做到这一点?
Could you give me some keywords,please? 请给我一些关键字吧?
Thanks! 谢谢!
real photo 真实照片
3d rendering photo (fake-like photo)
3d渲染照片(假照片)
A huge thing in fake images is the light reflection (very hard to get realistic). 伪造图像中的一大问题是光反射(很难使之逼真)。 Reflections or shadows that are too sharp or exact generally give away a fake image, so removing all the natural lighting, and then regenerating the lighting could give the effect your after.
过于尖锐或过于精确的反射或阴影通常会散发出假的图像,因此先去除所有自然光,然后再重新生成光,可能会给您带来效果。
To be able to do this well though, you will likely need to estimate surface normals which may be difficult if you are not in a controlled environment or know the object you are looking at quite well... 为了能够做到这一点,您可能需要估计表面法线,如果您不在受控环境中或知道要观察的物体很好,这可能会很困难。
