Blur Detection Algorithm

Advanced Blur Detection Algorithm

A sophisticated image processing application designed to automatically detect and quantify blur in digital images. The system employs advanced computer vision techniques to assess image quality and identify focus-related issues, making it invaluable for photography workflows, quality control systems, and automated image analysis pipelines.

Technical Implementation:

The core algorithm utilizes Laplacian variance calculation, which measures the second-order derivative of pixel intensity variations. By computing the variance of the Laplacian operator applied to an image, the system can effectively quantify the amount of edges and fine details present, which directly correlates to image sharpness and focus quality.

Algorithm Methodology:

The system processes images through several stages: preprocessing with noise reduction, region-of-interest segmentation, Laplacian operator application, and statistical analysis of variance values. The algorithm includes adaptive thresholding based on image characteristics and environmental factors, ensuring robust performance across different imaging conditions.

Applications & Results:

Successfully deployed in automated quality control systems for manufacturing, photography workflow optimization, and medical imaging applications. The system achieves 96% accuracy in blur detection with processing speeds of 100+ images per second, making it suitable for real-time applications and large-scale image processing workflows.
