Edge Detection via Edge-Strength Estimation Using Fuzzy Reasoning and Optimal Threshold Selection Using Particle Swarm Optimization

<div>Edge detection results of “goat” image: desired edge output of “goat” image; Sobel, Canny’s, and Roberts methods using thresholds = 0.05 and 0.15; fuzzy-BFA method; proposed method with fixed thresholds (0.18 and 0.35) and optimal threshold.</div>
