Use opencv and OS or pathlib Path gets the path name and image name, and saves the image to the specified path

 os.path and pathlib.Path be similar , But the latter simplifies many operations , There are many advantages that the former does not have .

（1）os library

os Module provides a very rich way to handle files and directories .

Python Basic course , Link directly to ：Python OS file / Catalog method | Novice tutorial (runoob.com)

among ,os.path() The module is used most frequently , It is usually used to get the attributes of files , There are many functions in it , This article only introduces ：

• os.path.join()   # Path synthesis
• os.path.split()  # Path segmentation

（2）pathlib.Path modular

This module provides classes that represent file system paths , These classes have features that apply to different operating systems （Window、Linux、macOS） The semantics of the .

Get absolute path or relative path Part of the ：

• # .name file name , Contains the suffix , If it is a directory, get the directory name
• # .stem file name , No suffix
• # .suffix Image suffix （ Format ）
• # .parent Parent directory
• # .parents All parent directories
• # .anchor anchor , The front part of the directory , Absolute path (C:\) Or relative path (/)

 （3） Code example （ With comments ）

import os
import cv2
from pathlib import Path

files_path = "demo1"
out_path = "demo_out/"

#  Traverse all files 
files = os.listdir(files_path)
for i, file in enumerate(files):
    print(file)

    img = os.path.join(files_path, file)  #  Combine directory and filename into a path 
    image = cv2.imread(img)

    # image = cv2.imread("{}/{}".format(files_path, str(file)))

    cv2.imwrite(out_path + file, image)

image_path = r"G:\CSDN\python\Office_skills\path\demo1\1.png"

#  Divide the path into  dirname  and  basename, Returns a tuple 
split_path = os.path.split(image_path)
print(split_path)

# .name  file name , Contains the suffix , If it is a directory, get the directory name 
# .stem  file name , No suffix 
# .suffix  Image suffix （ Format ）
# .parent  Parent directory 
# .parents  All parent directories 
# .anchor  anchor , The front part of the directory , Absolute path (C:\) Or relative path (/)
path = Path(image_path)
print(type(path))
print(path)
print(path.name)
print(path.stem)
print(path.suffix)
print(list(path.parents))  #  Tabular form 
print(path.anchor)

#  Read and save images 
image1 = cv2.imread(image_path)
save_path = out_path + path.name
cv2.imwrite(save_path, image1)
