Python Code for Processing Files and Saving Images

The code provided is used to process files in a directory and save the processed images to another directory.\n\nFirst, the code sets the directory paths for the input files and the output images. The input file directory is stored in the variable `file_dir`, and the output image directory is stored in the variable `save_dir.\n\nThen, the code checks if the output image directory exists. If not, it creates the directory.\n\nNext, the code retrieves the list of files in the input file directory using the `os.listdir()` function.\n\nAfter that, the code creates a log file to record the progress and information about the processing. The log file name includes the current date and time, as well as the subdirectory name.\n\nFinally, the code writes the file directory and save directory paths to the log file.
