Video- codeC评估者通过图像比较算法？ [英] Video-codec rater by image comparison algorithm?
问题描述
也许任何人都知道，如果这是可能的。 比较图像质量几乎IMPOSIBLE来形容毫不为主观影响。当有人得分的图像质量好，至少有一个人，那并不这么认为。 人类preferences总是不同的。
perhaps anyone knows if this is possible. comparing image quality is almost imposible to describe without subjective influences. When someone rates an image quality as good there is at least one person, that doesn't think so. human preferences are always different.
所以，我想知道是否有去率通过一种算法，比较原始图像的制作之一下列问题的图像质量。
So, I would like to know if there is away to "rate" the image quality by an algorithm that compares the original image to the produced one in following issues
- 颜色变化（由像素差值像素
- 模糊率
- 文物和宏块
第一个是最简单的一个，因为你可以在颜色检查只是diffeence，可以在+给3个值 - 每一个十六进制值 双方最后一次，我不知道这是可能的，但是阻塞可以通过边发现被检测出来。
the first one would be the easiest one because you could check just the diffeence in colours and can give 3 values in +- of each hex-value both last once I don't know if this is possible, but the blocking could be detected by edge-finding.
和国王的追求是做更多的则只是一个形象，因为视频是用几帧进行。
and the king's quest would be to do that for more then just one image, because video is done with several frames.
也许你专业程序员能告诉我，如果这样的自动算法中做才能带来一定的客观测量divice成等级的图像质量。这也许可以冷静下来一些H.264比X264比VP8和blaaah人好：）
perhaps you expert programmers could tell me, if such an automated algo can be done to bring some objective measurement divice into rating image quality. this could perhaps calm down some h.264 is better than x264 and better than vp8 and blaaah people :)
