将图像从RGB转换为HSV色彩空间 [英] Converting image from RGB to HSV color space

问题描述

我在Scipy或Matplotlib's文档中找不到这样的功能(即RGB_to_HSV())，并且Google除了[c3>配方中展示了rgb2hsv功能之外，没有显示指针，尽管在ActiveState上不可用Numpy数组保持不变.

I couldn't find such function (i.e. RGB_to_HSV()) in Scipy or Matplotlib's documentations, and Google doesn't show pointers, except ActiveState recipe which demonstrates rgb2hsv function, though not usable on Numpy array as is.

有人知道快捷方式吗?

对不起，刚刚找到matplotlib.colors.rgb_to_hsv()，这正是我想要的.我应该删除这个问题吗?

Sorry, just found matplotlib.colors.rgb_to_hsv() which is exactly what I was looking for. Should I delete this question?

推荐答案

Matplotlib提供RGB到HSV转换功能: matplotlib.colors.rgb_to_hsv():

Matplotlib provides RGB to HSV conversion function: matplotlib.colors.rgb_to_hsv():

matplotlib.colors.rgb_to_hsv(arr)

将numpy数组中的rgb值转换为hsv值，输入和输出数组应具有(M，N，3)形状

convert rgb values in a numpy array to hsv values input and output arrays should have shape (M,N,3)
