Determining the Fatigue Level of the Apple (Yellow DeliciousVar.) in a Fall from a Height onto the Surface of Various Materials using Image Processing

Apple is a kind of fruit which from harvest to delivery to the customer is placed under various loads. Bruise in various stages of displacement, transportation, packaging occurs due to brunt. In this study some of the factors affecting levels of apple bruise including drop height, material and level of storage at room temperature were investigated. The impact of these factors on apple bruise using a completely randomized design with fact orial experiment with three levels of drop height for 0.5, 1, 1.5 m, three level of wood, plastic, soil with thickness 9 mm and treated in triplicate with sets of 27 repetitions of each, were analyzed. The results showed the effect of surface height and gender on bruise level in 1% is meaningful (‏ p<‎)but the storage effect is not meaningful. By reducing heights, the bruise levels will be reduced. In height of 45cm bruise level will be456.42���� 2 and in height of 15cm the bruise level will be159.63���� 2 . It was also observed that with change of bruise surface from soil to wood crush level will be changed from 3.3���� 2 to 7.3���� 2 .
