Traditional fruit categorizations by humans in agricultural settings are inefficient, labor intensive and prone to errors. Automated grading systems not only speed up the time of the process but also minimize error. In this work, we propose and implement methodologies and algorithms that utilize digital image processing, content predicated analysis, and statistical analysis to detect, fuzzify, and classify the fruit dates. Our main contribution is design and development of an efficient algorithm for detecting and sorting dates. The system was accurate 85% of the times when compared to a human expert sorting. A larger sample size could help with tweaking the fuzzy system and improve the success rate. The proposed system is flexible and with minor changes can be adapted to other produce such as apples.
