Abstract:Abstract. This work presents an approach focused in enhancing the quality of tomato crops. We are developing and using low cost computational strategies to support early detection of the late blight. Our approach consorts tomatoes cultivars in an experimental field with inexpensive computer-aided resources based on Web and Android mobile tools in which workers collect scouting data and annotations and take images about the state of the crop, and in image filtering techniques and pattern recognition to detect f… Show more
“…The goal of this paper is to present novel computerbased techniques that increase the productivity of tomato crops on small properties in the state of Rio de Janeiro. In this study, we expand our previous works (Vianna & Cruz, 2013a, 2013bNunes et al, 2014, Cruz et al, 2015. The approach aims at supporting small farmers to detect late blight, a foliage disease in tomato crops, by using pattern recognition, more specifically based on Multilayer Perceptron (MLP) neural networks.…”
The food quality is a major issue in agriculture, economics, and public health. The tomato is one the most consumed vegetables in the world, having a significant production chain in Brazil. Its culture permeates many economic and social sectors. This paper presents a technological approach focused on enhancing the quality of tomatoes crops. The authors developed intelligent computational strategies to support early detection of diseases in Brazilian tomato crops. Their approach consorts real field experiments with inexpensive computer-aided experiments based on pattern recognition using neural networks techniques. The recognition tasks aimed at the identification foliage diseases named late blight, which is characterized by the incidence of brown spots on tomato leaves. The identification method achieved a hit rate of 94.12%, by using digital images in the visible spectrum of the leaves.
