Building a hyperspectral library of common bean diseases. Author(s): RIBEIRO, W. R.; ALMEIDA, A. de S.; FERREIRA, A. L.; SILVA, R. M.; ALVES, T. M.; GERALDINE, A. M.; SILVA, J. F. A. e; PINHEIRO, P. V.; LOBO JUNIOR, M. Sensors attached to unmanned aerial vehicles can detect diseased plants before they become symptomatic, according to differences in their reflectance. Despite the advances in hardware and methods for... ... Repository: BDPA Publication year: 2024
Vitamin C distribution in acerola fruit by near infrared hyperspectral imaging. Author(s): MALEGORI, C.; GRASSI, S.; MARQUES, E. J. N.; FREITAS, S. T. de; CASIRAGHI, E. The study aims at developing a methodology for qualitative mapping of nutraceutical compounds in fruit by near infrared hyperspectral imaging (NIR-HSI), focusing on vitamin C mapping in acerola (Malpi... ... Repository: BDPA Publication year: 2016
Proximal hyperspectral analysis in grape leaves for region and variety identification. Author(s): ARRUDA, D. C. de; DUCATI, J. R.; HOFF, R.; BELLOLI, T. F.; THUM, A. B. Reflectance measurements of plants of the same species can produce sets of data with differences between spectra, due to factors that can be external to the plant, like the environment where the plant... ...

Detecting wheat Fusarium head blight using hyperspectral imaging. Author(s): BARBEDO, J.; TIBOLA, C.; FERNANDES, J. M. The objective of this study was to detect FHB in wheat kernels using HSI. An algorithm, based on mathematical morphological operations and linear thresholding, was developed and implemented in order t... ... Repository: BDPA Publication year: 2015
Detection of sprout damage in wheat kernels using NIR hyperspectral imaging. Author(s): BARBEDO, J. G. A.; GUARIENTI, E. M.; TIBOLA, C. S. Repository: BDPA Publication year: 2018
Hyperspectral data analysis for chlorophyll content derivation in vineyards. Author(s): ARRUDA, D. C. de; DUCATI, J. R.; PITHAN, P. A.; HOFF, R. Quality and yield of a vineyard are related to canopy biomass and leaf vigor, and proximal techniques have been used as alternatives to conventional methods to estimate these parameters. Knowledge on... ... Repository: BDPA Publication year: 2024
Using hyperspectral images and the Fusarium Index for estimating deoxynivalenol concentration in wheat kernels. Author(s): BARBEDO, J. G. A.; TIBOLA, C. S. This paper presents a deeper study on the use of FI for estimating the DON concentration in wheat kernels, having as basis the original Fusarium Index algorithm and a comprehensive and carefully label... ... Repository: BDPA Publication year: 2015
Hyperspectral imaging for the detection of plant pathogens in seeds: recent developments and challenges. Author(s): FERREIRA, L. C.; CARVALHO, I. C. B.; JORGE, L. A. de C.; QUEZADO-DUVAL, A. M.; ROSSATO, M. Food security, a critical concern amid global population growth, faces challenges in sustainable agricultural production due to significant yield losses caused by plant diseases, with a multitude of t... ...
