Sorts out blurry images in the current dir prepending an underscore to their names
import os
import cv2
def is_image_blurry(image):
# Для анализа конвертируем изображение в оттенки серого
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
# Вычисляем оценку размытости изображения с использованием оператора Лапласа
# Оператор Лапласа выделяет границы объектов на изображении
# Далее вычисляется дисперсия значений пикселей на полученном изображении
