Реализация распознования цвета в программе на PyQt

[maroonlok]

Доброго дня. Кто сможет подскажите, как реализовать программу на PyQt5. Которая сможет распозновать цвет с загружаемой картинки и выводить данные о цветах в таблицу созданную в программе.

пробовал использовать OpenCV для распознования, но не пойму как объединить с PyQt.

import cv2
import numpy as np

img_path = "-5 (2).jpg"

img = cv2.imread(img_path)
resize_img = cv2.resize(img  , (1500 , 700))
b = g = r = 0
clicked = False
def color_function(event, x, y, flag, param):
    if event == cv2.EVENT_LBUTTONUP:
        global b, r, g, clicked
        b, r, g = resize_img[y, x]
        b = int(b)
        g = int(g)
        r = int(r)
        clicked = True



cv2.namedWindow("main")
cv2.setMouseCallback("main", color_function)

while True:
    cv2.imshow("main", resize_img)
    resize_img = cv2.resize(img, (1500, 700))
    if clicked:
        cv2.rectangle(img, (20, 20), (1500, 60), (b, g, r))
        if b + g + r <= 500:
            cv2.putText(img, "R =" + str(r) + "; G = " + str(g) + "; B = " + str (b), (200, 250), 2, 1.0, (255, 255, 255))
        else:
            cv2.putText(img, "R =" + str(r) + "; G = " + str(g) + "; B = " + str(b), (200, 250), 2, 1.0, (0, 0, 0))
        clicked = False

    if cv2.waitKey(20) & 0xFF == 27:
        break
cv2.destroyAllWindows()

Почитай про skimage io imread(path)
Просто открываешь картинку как массив, там есть строки и столбцы, берешь нужный элемент по координатам, это будет список с RGB
