The design of an intelligent system for qualitative evaluation of beans product impurities is the most important step necessary to make a bean sorting machine. In this research, a real-time system of pinto beans sorting (from red, white, and damaged beans, and stones) was designed and developed by combining image processing and artificial neural networks (ANNs). In total, six parameters were selected from the statistical characteristics of beans for classification of pinto beans from other beans and stones. Several ANN classifiers each with different number of neurons in the hidden layer were trained to determine the optimal structure. Optimal topology of ANN classifier was 6-12-8-2. In the first step the offline system was evaluated. The correct classification rate for pinto, white, red, and damaged beans and stones were 86.27, 100, 100, 54.9 and 65.3%, respectively. The average accuracy of offline method was 81.2%. The corresponding MSE were calculated as 0.05, 0.059, 0.013, 0.099 and 0.096, respectively. The accuracy of the online sorting system for pinto bean from others was 97.87%. The results showed that the designed system combined with ANN technique had acceptable efficiency in pinto been grading.

Tomato faces pathogen attack which is a major cause of postharvest losses. The present study is carried out to minimise its postharvest losses and to extend its shelf life by physical elicitors such as photosensitisation, ozone and UV-C. The quality of the fruit was evaluated by the quantitative analysis of physico-chemical, biochemical and enzymatic assay at a regular interval of 5 d during storage. The results showed significantly higher levels of total phenols, ascorbic acid, carotene, lycopene and the antioxidant activity throughout their storage as compared to control. The fruits of T5 group (photosensitisation and ozone gas treatment) remained marketable up to 40 d, while the non-treated fruits were acceptable up to 22 d. The nutritional quality of stored tomato was also found better in treated fruit than control. These results suggest that the photosensitisation and ozone is found effective in the postharvest extension of tomato and maintaining their nutritional quality.
