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
Selection of NIR wavelengths from hyperspectral imaging data for the quality evaluation of acerola fruit. Author(s): MALEGORI, C.; GOWEN, A.; MARQUES, E.; AVELAR, M. F. P.; FREITAS, S. T. de; PASQUINI, C.; CASIRAGHI, E. The aim of this work is to evaluate Acerola post-harvest quality using NIR hyperspectral imaging. Repository: BDPA Publication year: 2015
Determination of fumonisin content in maize using near-infrared hyperspectral imaging (NIR-HSI) technology and chemometric methods. Author(s): CONCEIÇÃO, R. R. P.; QUEIROZ, V. A. V.; MEDEIROS, E. P. de; ARAUJO, J. B. de; SILVA, D. D. da; MIGUEL, R. de A.; STOIANOFF, M. A. R.; SIMEONE, M. L. F. Maize (Zea mays L.) is of socioeconomic importance as an essential food for human and animal nutrition. However, cereals are susceptible to attack by mycotoxin-producing fungi, which can damage health... ... Repository: BDPA Publication year: 2024
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... ...

Detecção de Giberela em trigo usando processamento digital de imagens na banda do infravermelho próximo. Author(s): BARBEDO, J. G. A.; TIBOLA, C. S.; FERNANDES, J. M. C. Dentre as principais doenças que atacam o trigo, a giberela é de particular interesse. Esta doença, além de causar perdas na produção, está associada também à presença da micotoxina chamada deoxinival... ... Repository: BDPA Publication year: 2014
Considerações sobre o cálculo do coeficiente angular da regressão linear entre o espectro de referência e o espectro da imagem em mistura espectral. Author(s): CARVALHO JUNIOR, O. A. de; GUIMARÃES, R. G.; CARVALHO, A. P. F. de; GOMES, R. A. T.; MARTINS, E. de S. O presente trabalho discute o emprego do cálculo do coeficiente angular de uma regressão linear simples com objetivo de quantificar e identificar um determinado mineral na imagem. O emprego da regress... ... Repository: BDPA Publication year: 2005
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... ...
