Blur Detection (OpenCV)

A tiny Python script that detects whether an image is blurry using the classic Variance of Laplacian focus measure.

It prints the result and opens a window showing the image with an overlaid label and score.

How it works

• Converts the image to grayscale
• Computes Laplacian(gray).var()
• Compares against a threshold (currently 100.0 in app.py)

Requirements

• Python 3
• OpenCV (opencv-python)
• imutils (imported in the script)

Usage

python app.py --image path/to/image.jpg

Customize

• Tune the blur threshold in app.py:

threshold = 100.0
