When we deal with photos or pictures, we find that the outline of the main body edge in the picture is not clear enough, and the details feel lack of texture, which is usually caused by jitter, inaccurate focus or compression of the picture. Setting the sharpening of the picture can enhance the edge contrast, make the picture look clearer and have more visual impact, which is a key step to improve the quality of the picture. Whether it is e-commerce product map, social media sharing or work report, a clear and sharp picture can always give a more professional image. So how can we avoid the inefficiency caused by processing pictures one by one under ordinary circumstances?
Here are four practical methods to help us quickly complete the sharpening of pictures and make the edge contours of each picture clear in batches.
When to set the sharpening degree of JPG and PNG images?
Scanned text is slightly blurred
paper documents or chat screenshots may be slightly blurred and grayscale, resulting in unclear text edges. A slight increase in sharpening can make text boundaries clearer and make reading easier. If the document is to be printed or sent to others, moderate sharpening can make the content clearer.
Enhance visual impact when displaying
when making covers, display pictures or pictures sent to the platform, some original pictures look very plain and not very attractive to others. Appropriate sharpening can make the texture of the product more obvious, but the color level is more prominent, making the whole look more textured. Even small white users can make the picture look more professional and more eye-catching through simple sharpening adjustments.
Images enhance clarity
the photos taken may make the edge line details of the picture look unsatisfactory due to jitter, poor light and other reasons. Adjusting the sharpening degree can make the edge more distinct and make the picture look clearer. For example, the hair of the character and the edge of the text can be more prominent, thus improving the visual effect.

import OS
input_folder = "./input_images"
output_folder = "./output_images"
Sharpen_factor=2.0 # Sharpening intensity, usually 1.0-3.0
if not OS .path.exists(output_folder):
OS .makedirs(output_folder)
for filename in OS .listdir(input_folder):
if filename.lower().endswith(('.png', '.jpg', '.jpeg')):
img = Image.open( OS .path.join(input_folder, filename))
#Apply sharpening filter
img_sharpened = img.filter(ImageFilter.UnsharpMask (
