如何最好地对视频帧颜色进行全局定量分析
我正在尝试分析 mp4 视频并将其视频内容转换为某种数字数组。其中数字代表框架的“全局”颜色。 这些帧本质上是灰度帧。 最终想分析图像中最亮的全局颜色的频率。
谁能建议最好（最简单）的解决方案？ 非常感谢您的查看和任何建议。
I am trying to analyse an mp4 video and convert it's video content into some sort of array of numbers. where the numbers would represent the "global" color of the frame.
The frames are essentially grayscale frames.
Eventually would like to analyse the frequency of a the lightest global color in the image.
Can anyone suggest the best (simplest) solution?
Thanks very much for looking and any suggestions.

您是否尝试过研究计算机视觉库 [OpenCV1？
它支持多种视频格式，例如 mp4。
直方图功能听起来非常接近您想要的。
我不确定你所说的最浅颜色是什么意思（这是否意味着 HSV 颜色空间中的最低饱和度？）等等。您可以在 OpenCV 中探索大量的颜色空间转换和其他功能。
Have you tried looking into [OpenCV1, the computer vision library?
It has support for many video formats such as mp4.
The histogram functionality sounds very close to what you want.
I'm not sure what you mean by lightest color (does that mean lowest saturation in HSV color space?) etc. There's plenty of color space conversion and other functionality that you can explore in OpenCV.
