Abstract
In addition to size, export quality requirements for gedong mango among others are clean surface, free of damaged mechanically or biologically, free from pests and diseases, and normal fruit shape. The abnormal fruit shape in mangoes is known as sitting mango, which is not easy to roll over when pushed because the fruit surface is flat on certain sides. Several dimensionless shape factors can be used to identify the shape of an object through image processing. Some shape factors that are often used to identify shapes of object in image processing include roundness, roundness ratio, sphericity, axial ratio, inequality degree of projected area and spherical disproportion. This study aims to identify the shape of the fruit using several dimensionless shape factors and determine the shape factors that can be used to distinguish normal and abnormal fruit shapes for gedong mangoes. The results showed that abnormal and normal mango gedong fruit shapes could be distinguished by image processing using the roundness, sphericity, and spherical disproportion form factors in certain deviant shapes but not for all samples.
