显示一个二维 numpy 数组，其中内容是元组作为图像

Question

I have a 2d (M * N) numpy array, where each cell contains a tuple of length 3. The tuple contains R, G, and B values for each pixel, eg

A[0,0] = (0, 255, 0)

Is there a way to show this array as an image, possibly without the need to transform it first to a 3d (M * N *3) array?

Answer 1

Image from PIL should be able to generate a picture from a M*N matrix with RGB as a tuple.

from PIL import Image
import numpy as np
matrix = np.array([[(100,100,100),(100,100,100),(100,100,100)],[(100,100,100),(100,255,100),(100,100,100)],[(100,100,100),(100,100,100),(100,100,100)]])
im = Image.fromarray(matrix, 'RGB')
im.show()
