Abstract
Digital color imaging techniques are becoming powerful experimental tools that provide physical information of agricultural products nondestructively without any hazards. Digital imaging techniques combined with role based algorithms will suggest a perfect solution for nondestructive quality evaluation of agricultural and food products.
The inspection chamber and the camera were designed and constructed to allow future upgrade to a commercial handling system. The Orange was put inside the chamber under the camera and six images were digitized, with a 90° rotation between successive views. Image processing techniques were developed to find the boundaries of the fruit, boundaries of the defected areas, features for those areas, and decide which defect this area belongs to.
Morphological features were identified for each area to analyze the fruit quality by deciding which defect this fruit has, including Compactness, roundhess, elongation, and roughness were chosen and defined for the shape factors. The shape factors, of which values were a maximum of one for a circle, were derived from area, perimeter,
