Última Development of a portable system for detection of leaf area in plants 111 Roa Guerrero, Edgar Eduardo; Bonilla Gonzalez, Johnatan; Numpaque López, Humberto; Cifuentes Guerrero, Pedro Luis. Recently, the determination of leaf area and growth rates in plants through portable devices has become popular due to the advantages offered by artificial vision systems to identify and classify objects using images. The purpose of the research was to develop a portable system for measuring leaf area through image recognition. The methodology includes 3D designs, acrylic device building, determining the area in pixels by the technique of radial basis neural networks (RBFN) directly in the RGB color space and pixel conversion to cm2. The results obtained by analysis of variance for each species showed that the p-value was greater than 0.86 for each class of plants. Moreover, the system obtained coefficients of determination higher to 0.90 for Orange...
