Image Processing of Product Surface Defect Using Scilab

— The defect is an imperfection that impairs worth or utility. The defects show some disorder of the product and it is opposite the standard or criteria that have been stated.. In order to define the defect, some techniques are being used. One of the technique is using image processing. The image will be captured by the camera and the image appear will be imported to the Scilab software to read it. Otherwise, the image will be translated into histogram graph to show the frequency (pixel) and grayscale value of the defect.Index Terms— Defect image, surface defect, grayscale image, Scilab software, histogram graph
