RF-MEP: A novel random forest method for merging gridded precipitation products and ground-based measurements
(Elsevier, 2020)
The accurate representation of spatio-temporal patterns of precipitation is an essential input for numerous environmental applications. However, the estimation of precipitation patterns derived solely from rain gauges is ...
The role of gas in the merging of massive black holes in galactic nuclei
(Merloni, A.Nayakshin, S., 2005)
Using high-resolution SPH numerical simulations, we investigate the effects of gas on the inspiral and merger of a massive black hole binary. This study is motivated by the very massive nuclear gas disks observed in the ...
Algoritmo ejeção-absorção metropolizado para segmentação de imagens
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2014-12-19)
We proposed a new split-merge MCMC algorithm for image segmentation. We describe how an image can be subdivided into multiple disjoint regions, with each region having an associated latent indicator variable. The latent ...
High-resolution satellite-gauge merged precipitation climatologies of the tropical Andes
(Wiley-Blackwell, 2016-02-09)
Satellite precipitation products are becoming increasingly useful to complement rain gauge networks in regions where these are too sparse to capture spatial precipitation patterns, such as in the Tropical Andes. The Tropical ...

Dense urban elevation models from stereo images by an affine region merging approach
(2006)
The main subject of this thesis is the computation of Dense Disparity Maps from a pair of satelite or aerial stereo images from an urban scene, taken from two different viewpoints. Several steps are needed to obtain the ...

Building roof contour extraction from LiDAR data
(2011-12-01)
This paper proposes a method for the automatic extraction of building roof contours from a LiDAR-derived digital surface model (DSM). The method is based on two steps. First, to detect aboveground objects (buildings, trees, ...
