Streamlined approaches for image classification using principal component analysis and hierarchical clustering of extrudates from coffee and sorghum blends. Author(s): HIDALGO CHÁVEZ, D. W.; SILVA, F. L. C. DA; PINTO, R. V.; CARVALHO, C. W. P. de; FREITAS-SILVA, O. This article describes simple methods to group images including principal component analysis (PCA) and hierarchical clustering of principal components (HCPC). Images of expanded and low expanded extru... ... Repository: BDPA Publication year: 2023

Method for maize plants counting and crop evaluation based on multispectral images analysis. Author(s): VERAMENDI, W. N. C.; CRUVINEL, P. E. The processing of multispectral images acquired with embedded cameras in unmanned aerial vehicles (drones) has brought new opportunities for precision agriculture. In this study a method for evaluatin... ... Repository: BDPA Publication year: 2024
Multivariate analysis of images in spectrophotometric methods: quantification of soil organic matter. Author(s): MORAIS, P. A. de O.; SOUZA, D. M. de; MADARI, B. E. Soil organic matter (SOM) is usually quantified by Walkley-Black titration method or using a spectrophotometric method. This study proposes an alternative method for quantification of SOM using digita... ... Repository: BDPA Publication year: 2021
Saturated salt accelerated aging and computerized analysis of seedling images to evaluate soybean seed performance. Author(s): YAGUSHI, J. T.; COSTA, D. S.; FRANÇA-NETO, J. de B. ABSTRACT: Seed deterioration causes losses to seed companies during the storage. For researches, the challenge has been to develop techniques which improve the seed longevity as well as laboratory ana... ... Repository: BDPA Publication year: 2014
