Simplified input directory of images

[git9875]

Bread/datasets/low_light_test.py

Line 13 in e0c5068

subsets = os.listdir(root)

The code block can be replaced with this:

directory_name = os.path.basename(root)
print("directory_name", directory_name)
img_files = os.listdir(root)
for img_file in img_files:
    if not (img_file.endswith('.jpg') or img_file.endswith('.jpeg') or img_file.endswith('.gif') or img_file.endswith('.png')):
        continue
    self.items.append((
        os.path.join(root, img_file),
        directory_name,
        img_file
    ))

This enables the "root" directory for the dataset to be the intended input directory of images, without requiring any subdirectories.
