Mini toolsDefinition
A technique that identifies boundaries of objects within images by detecting discontinuities in brightness.
Detailed Explanation
Edge detection algorithms identify significant changes in image intensity values which typically correspond to object boundaries. Common methods include gradient-based operators Sobel Prewel second-derivative operators Laplacian and more advanced techniques like Canny edge detection. These algorithms typically involve filtering enhancement and thresholding steps.
Use Cases
1. Object outline detection 2. Medical image analysis 3. Industrial inspection 4. Document analysis
