因此，我編寫了這段小代碼，嘗試將RGBimge轉換為Grayscale從該已接受答案中獲取的代碼。問題是，即使我只是重新創建原始圖像，它也顯示出與原始圖像不相似的神秘圖像。您認為問題是什么，我們應該如何解決呢？另外，我想將其轉換Grayscale為給定的數組b。這是我的代碼：import matplotlib.image as imgimport matplotlib.pyplot as pltfrom PIL import Imageimport numpy as npa = img.imread('hCeFA.png')a = a * 255         #Matplotlib gives float values between 0-1b = a * np.array([0.3, 0.59, 0.11])b = np.sum(b, axis = 2) / 3           #Grayscale conversionimg1 = Image.fromarray(a, 'RGB')img1.save('my.png')img1.show()                     #Gives a cryptic imageplt.imshow(a/255, interpolation='nearest')     #Works fineplt.show()
