In this work, the concept of data fusion is applied to nondestructive testing data for
classification of fresh intact tomatoes based on their ripening stages. A Bayesian classifier
considering a multivariate, three-class problem was incorporated for data fusion. Probability
of error was estimated numerically for univariate and multivariate cases based on
Bhattacharyya distance. Numerical results showed that multi-sensorial data fusion reduces
the classification error considerably. The Bayesian classifier was tested on data of tomato�…
In this work, the concept of data fusion is applied to nondestructive testing data for classification of fresh intact tomatoes based on their ripening stages. A Bayesian classifier considering a multivariate, three-class problem was incorporated for data fusion. Probability of error was estimated numerically for univariate and multivariate cases based on Bhattacharyya distance. Numerical results showed that multi-sensorial data fusion reduces the classification error considerably. The Bayesian classifier was tested on data of tomato fruits taken by the following nondestructive tests: colorimeter and acoustic impact. Results of Bayesian classifier agree with numerical estimations showing an 11% classification error in the multivariate (multi-sensor) case compared with a 48% obtained by the univariate case (single sensor).
