Determination of Unsound Concrete using Non-Destructive Testing in a Smooth Concrete through various Image Processing Techniques

The researchers have developed a device that utilizes different image processing techniques that include Grayscale, Gaussian blur, Binary thresholding, Morphology, Contour, and Flood fill to determine a crack or spall width area. The Image capturing device that the researchers created also classifies if the said crack or spall can still be tolerable or needs structural consultation based on the thresholds set. The device has a graphical user interface that captures the images of crack or spall, measuring its width and area and classification if tolerable or needs structural consultation.
