Grading of Carabao Mango Using Image Processing

Grading the Quality of the mango is usuallyhandled physically which might not beaccurate due to the judgement of a person. Inthis study, image processing using MATLABis proposed using Mandami-FuzzyInterference System. The Mango is placed onchamber to help the camera in collecting theRed-Green-Blue (RGB) data and the spotdata of the program. This woodenrectangular chamber includes three LEDflashlights and the camera. The resultsshowed that Red mean value less than orequal to 155 are acceptable. The blemishesand maturity of the mango is then analysedbased in the white spots from the image andred means of the image. The paper alsoincludes size detection using boundarytracing and spot detection using the regionprops function. The results show that theprogram is accurate enough to grade themango. The system is strict enough to rejectthe sample mango if it is too large, is toosmall, is yellow or is blemished
