使用python如何删除同一文件夹下相似的图片

时间:2021-10-25 10:40     来源/作者:MHyourh

前言

最近整理图片发现,好多图片都非常相似,于是写如下代码去删除,有两种方法:

注:第一种方法只对于连续图片(例一个视频里截下的图片)准确率也较高,其效率高;第二种方法准确率高,但效率低

方法一:相邻两个文件比较相似度,相似就把第二个加到新列表里,然后进行新列表去重,统一删除。

例如:有文件1-10,首先1和2相比较,若相似,则把2加入到新列表里,再接着2和3相比较,若不相似,则继续进行3和4比较…一直比到最后,然后删除新列表里的图片

代码如下:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
import cv2
from skimage.measure import compare_ssim
# import shutil
# def yidong(filename1,filename2):
#     shutil.move(filename1,filename2)
def delete(filename1):
    os.remove(filename1)
if __name__ == '__main__':
    path = r'D:\camera_pic\test\rec_pic'
    # save_path_img = r'E:\0115_test\rec_pic'
    # os.makedirs(save_path_img, exist_ok=True)
    img_path = path
    imgs_n = []
    num = []
    img_files = [os.path.join(rootdir, file) for rootdir, _, files in os.walk(path) for file in files if
                 (file.endswith('.jpg'))]
    for currIndex, filename in enumerate(img_files):
        if not os.path.exists(img_files[currIndex]):
            print('not exist', img_files[currIndex])
            break
        img = cv2.imread(img_files[currIndex])
        img1 = cv2.imread(img_files[currIndex + 1])
        ssim = compare_ssim(img, img1, multichannel=True)
        if ssim > 0.9:
            imgs_n.append(img_files[currIndex + 1])
            print(img_files[currIndex], img_files[currIndex + 1], ssim)
        else:
            print('small_ssim',img_files[currIndex], img_files[currIndex + 1], ssim)
        currIndex += 1
        if currIndex >= len(img_files)-1:
            break
    for image in imgs_n:
        # yidong(image, save_path_img)
        delete(image)

方法二:逐个去比较,若相似,则从原来列表删除,添加到新列表里,若不相似,则继续

例如:有文件1-10,首先1和2相比较,若相似,则把2在原列表删除同时加入到新列表里,再接着1和3相比较,若不相似,则继续进行1和4比较…一直比,到最后一个,再继续,正常应该再从2开始比较,但2被删除了,所以从3开始,继续之前的操作,最后把新列表里的删除。
