Multitemporal segmentation of Sentinel-2 images in an agricultural intensification region in Brazil. Author(s): SANTOS, L. T. dos; WERNER, J. P. S.; REIS, A. A. dos; TORO, A. P. G.; ANTUNES, J. F. G.; COUTINHO, A. C.; LAMPARELLI, R. A. C.; MAGALHÃES, P. S. G.; ESQUERDO, J. C. D. M.; FIGUEIREDO, G. K. D. A. ABSTRACT: With the recent evolution in the sensor's spatial resolution, such as the MultiSpectral Imager (MSI) of the Sentinel-2 mission, the need to use segmentation techniques in satellite images ha... ...

Deep learning architectures for semantic segmentation and automatic estimation of severity of foliar symptoms caused by diseases or pests. Author(s): GONÇALVES, J. P.; PINTO, F. A. C.; QUEIROZ, D. M.; VILLAR, F. M. M.; BARBEDO, J. G. A.; DEL PONTE, E. M. Colour-thresholding digital imaging methods are generally accurate for measuring the percentage of foliar area affected by disease or pests (severity), but they perform poorly when scene illumination... ...

A segmentation approach to delineate zones for differential nitrogen intervention. Author(s): OLIVEIRA, R. P. de; WHELAN, B.; MCBRATNEY, A. Multi-source and -temporal data integration is expected to support the delineation of within-field management zones that may better conform to unique combinations of crop yield variations. This work a... ... Repository: BDPA Publication year: 2013
Segmentation of optical remote sensing images for detecting homogeneous regions in space and time. Author(s): COSTA, W. S.; FONSECA, L. M. G.; KÖRTING, T. S.; SIMÕES, M.; BENDINI, H. N.; SOUZA, R. C. M. With the amount of multitemporal and multiresolution images growing exponentially, the number of image segmentation applications is recently increasing and, simultaneously, new challenges arise. Hence... ... Repository: BDPA Publication year: 2017
A case study for a multitemporal segmentation approach in optical remote sensing images. Author(s): COSTA, W.; FONSECA, L.; KÖRTING, T.; SIMÕES, M.; KUCHLER, P. Continuous observations from remote sensors provide high temporal and spatial resolution imagery, and better remote sensing image segmentation techniques are mandatory for efficient analysis. Among th... ... Repository: BDPA Publication year: 2018
Bayesian segmented regression model to evaluate the adaptability and stability of maize in Northeastern Brazil. Author(s): OLIVEIRA, T. R. A. de; CARVALHO, H. W. L. de; NASCIMENTO, M.; SUELA, M. M.; CARDOSO, M. J.; OLIVEIRA, G. H. F. Although maize is one of the main crops in the Northeast region, yield is still considered low when compared to other regions. One of the main solutions to increasing yield is the selection of cultiva... ... Repository: BDPA Publication year: 2023
Automatic segmentation of the self-organizing map to support territorial zoning. Author(s): BARRETO, P. V. DE A.; SILVA, M. A. S. da; MATOS, L. N.; MIRANDA JÚNIOR, G. F.; DOMPIERI, M. H. G.; MOURA, F. R. DE; RESENDE, F. K. S. ABSTRACT: This paper proposes an algorithm for analyzing clusters of thematic maps with ordinal categorical classes to support territorial zoning. The proposed method combines the Self-Organizing Map... ... Repository: BDPA Publication year: 2023
Land use/land cover classification and scale effect analysis for a multi-temporal superpixel-based segmentation using PlanetScope data. Author(s): BUENO, I. T.; ANTUNES, J. F. G.; TORO, A. P. S. G. D.; WERNER, J. P. S.; LAMPARELLI, R. A. C.; COUTINHO, A. C.; FIGUEIREDO, G. K. D. A.; ESQUERDO, J. C. D. M.; MAGALHÃES, P. S. G. This study evaluated the accuracy and suitability of LULC classifications based on the scale effect of a multi-temporal superpixel-based segmentation using PlanetScope (PS) data. Repository: BDPA Publication year: 2023
Automatic 3D plant reconstruction from photographies, segmentation and classification of leaves and internodes using clustering. Author(s): SANTOS, T. T.; UEDA, J. Highlights: A stereo approach for 3D plant modelling is presented. Using only a set of photographies, the method produces a dense 3D point cloud that samples the plant surface. Clustering automaticall... ... Repository: BDPA Publication year: 2013
Self-guided segmentation and classification of multi-temporal landsat 8 images for crop type mapping in southeastern Brazil. Author(s): SCHULTZ, B.; IMMITZER, M.; FORMAGGIO, A. R.; SANCHES, I. D. A.; LUIZ, A. J. B.; ATZBERGER, C. Abstract: Only well-chosen segmentation parameters ensure optimum results of object-based image analysis (OBIA). Manually defining suitable parameter sets can be a time-consuming approach, not necessa... ... Repository: BDPA Publication year: 2015
