HSV image formation in python

Question

I have 3 (512×512) numpy arrays representing the Hue, Saturation and Value channels of my desired HSV image, containing float values.

How do I construct a single 512×512 image from these 3 numpy arrays?

Answer 1

To create an HSV image from the 3 channels, you can put them in a numpy array and transpose it to convert the shape from (3, 512, 512) to (512, 512, 3):

hsv = np.transpose([h, s, v], (1, 2, 0))

With OpenCV you can also use cv2.merge .
