The study sought to precisely determine the dimensions of Harumanis mango fruit while they are still attached to the tree, using digital image processing methods. Harumanis mangoes images were photographed at varying distances (1, 2, and 3 meters) and heights (0.5, 1, and 1.5 meters) using a camera and then analysed with MATLAB software. The study showed that the lowest percentage errors for fruit length and width were 1.16% and 0.22%, respectively, when the camera was placed 2 meters away and 1 meter above the fruits. The average growth rate of fruit width and length was found to be around 1 cm/week and 0.44 cm/week, respectively, using digital image analysis. The coefficient of determination (R2) values for fruit length and width was 0.79 and 0.88, respectively, indicating the dependability of the estimated results. This method can be utilized to monitor the fruit's sizes, effectively replacing the tedious manual measuring procedure.

Abstract

The study sought to precisely determine the dimensions of Harumanis mango fruit while they are still attached to the tree, using digital image processing methods. Harumanis mangoes images were photographed at varying distances (1, 2, and 3 meters) and heights (0.5, 1, and 1.5 meters) using a camera and then analysed with MATLAB software. The study showed that the lowest percentage errors for fruit length and width were 1.16% and 0.22%, respectively, when the camera was placed 2 meters away and 1 meter above the fruits. The average growth rate of fruit width and length was found to be around 1 cm/week and 0.44 cm/week, respectively, using digital image analysis. The coefficient of determination (R2) values for fruit length and width was 0.79 and 0.88, respectively, indicating the dependability of the estimated results. This method can be utilized to monitor the fruit's sizes, effectively replacing the tedious manual measuring procedure.
