OpenCV Python equalizeHist彩色图像 [英] OpenCV Python equalizeHist colored image

问题描述

我需要对彩色图像进行直方图均衡化.

I need to do a histogram equalization for a colored image.

首先，我将彩色图像转换为灰色，并将其提供给equalizeHist函数:

First I convert the colored image to gray and give it to the equalizeHist function:

image = cv2.imread("photo.jpg")
image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
cv2.equalizeHist(image)
cv2.imshow("equalizeHist", image)
cv2.waitKey(0)

但是在此之后，我需要将图像转换回RGB.我该怎么办?

But after this I need to convert the image back to RGB; how can i do that?
