ABSTRACT

In the past few decades, both academicians and industries have shown interest toward the agricultural post-harvest operation aiming to reduce the post-harvest losses. In order to assist farmers in post-harvest decision-making some effective and innovative methodological frameworks are required. The fruit weight measurement is of prime importance in many food processing industries during sorting, grading, and packaging. In this work, different Support vector machine (SVM) classifiers as well as weighing models developed using the optimized adaptive neuro-fuzzy inference system (ANFIS) coupled with a computer vision system are proposed. More precisely, the weighing models based on the hybrid ANFIS approach using two well-known optimization algorithms are analyzed. In the first approach, a series of GA-ANFIS models have been evaluated for different population size. In the later approach, different PSO-ANFIS models have been evaluated by varying the most influential parameters. The comprehensive self-built color image database has been used for both calibration and validation of the models. From an economic point of view, this indirect way of weighing fruits may be useful to fruit growers and traders in deciding the market depending on the fruit size and weight before packaging. The result shows the higher reliability and prediction capability of the proposed meta-heuristics (GA-ANFIS) model in estimating the weight of sweet lime fruit.
