获得不同干扰程度的模糊图像

同时对一共父级文件夹遍历。获得对应不同干扰程度的模糊图像

# This is

import cv2
import numpy as np

def reduce_resolution(image, factor):

    height, width, _ = image.shape    # 获取原始图像的宽度和高度

    new_width = int(width / factor) # 计算新的宽度和高度
    new_height = int(height / factor)

    # 使用resize方法来缩小图像分辨率，保持尺寸不变
    resized_image = cv2.resize(image, (new_width, new_height), interpolation=cv2.INTER_AREA)
    return resized_image

def motion_blur(image, degree=12, angle=45):
    image = np.array(image)

    # 这里生成任意角度的运动模糊kernel的矩阵， degree越大，模糊程度越高
    M = cv2.getRotationMatrix2D((degree / 2, degree / 2), angle, 1)
    motion_blur_kernel = np.diag(np.ones(degree))
    motion_blur_kernel = cv2.warpAffine(motion_blur_kernel, M, (degree, degree))

    motion_blur_kernel = motion_blur_kernel / degree
    blurred = cv2.filter2D(image, -1, motion_blur_kernel)

    # convert to uint8
    cv2.normalize(blurred, blurred, 0, 255, cv2.NORM_MINMAX)
    blurred = np.array(blurred, dtype=np.uint8)
    return blurred
