PIL與cv2讀入圖片的區別

plt.imread和PIL.Image.open讀入爲RGB，cv2.imread讀入爲BGR，轉換RGB和BGR方式：

PIL與cv2轉換代碼：

def PILImageToCV(path):
    # PIL Image轉換成OpenCV格式
    img = Image.open(path)
    
    plt.subplot(121)
    plt.imshow(img)

    img = cv2.cvtColor(np.asarray(img), cv2.COLOR_RGB2BGR)
    plt.subplot(122)
    plt.imshow(img)
    plt.show()


def CVImageToPIL(path, ):
    # OpenCV圖片轉換爲PIL image
    img = cv2.imread(path)
    img = img[:, :, [2,1,0]]
    # cv2.imshow("OpenCV",img)
    plt.subplot(121)
    plt.imshow(img)

    img2 = Image.fromarray(cv2.cvtColor(img, cv2.COLOR_BGR2RGB))
    # plt.subplot(122)
    #plt.imshow(img2)
    plt.show()
