Metaheuristic Optimized Edge Detection for Recognition of Concrete Wall Cracks: A Comparative Study on the Performances of Roberts, Prewitt, Canny, and Sobel Algorithms

<div>The proposed model for recognition of cracks on the concrete wall surface (MO-EDCR). Note: <i>W</i> denotes the window size parameter. <i>T</i><sub>E</sub> is the edge detection threshold. Th<sub>m</sub> is a threshold parameter used in the morphological operation for small object removal.</div>
