Melhorando a estimação de pose com o RANSAC preemptivo generalizado e múltiplos geradores de hipóteses
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Sistemas e ComputaçãoCiência da Computação, 2014-02-27)
The camera motion estimation represents one of the fundamental problems in Computer
Vision and it may be solved by several methods. Preemptive RANSAC is one of them,
which in spite of its robustness and speed possesses ...
RANSAC-BASED SEGMENTATION FOR BUILDING ROOF FACE DETECTION IN LiDAR POINT CLOUD
(Ieee, 2018-01-01)
This work proposes a method for segmenting the roof planes of buildings in Light Detection and Ranging (LiDAR) data. First, a preprocessing of the point cloud is performed to separate the points belonging to each building. ...

Extraction of building roof planes with stratified random sample consensus
(2018-09-01)
This paper describes a consensus-set estimation for building roof-plane detection using a stratified random sample consensus (sRANSAC) algorithm applied to point clouds acquired by laser scanning systems. The main idea is ...
Combining Edge and One-Point RANSAC Algorithm to Estimate Visual Odometry
(2013-07-28)
In recent years, classical structure from motion based SLAM has achieved significant results. Omnidirectional camera-based motion estimation has become interested researchers due to the lager field of view. This paper ...
StitchingPHm-A new algorithm for panoramic images
(2014-01-01)
In this paper it is presented a new algorithm for the construction of panoramic images (including 360 panoramas), which has as main characteristic to avoid the distortion that occurs by joining of several successive images ...
Evaluation of the Hough and RANSAC methods for the detection of circles in biological tests
(Proceedings of SPIE - The International Society for Optical Engineering, 2020)
TSRS - A new approach for traffic sign recognition using the sift algorithm
(2019-01-01)
This paper proposes a new approach for traffic sign recognition using images captured by a low-cost mapping system. The proposed approach applies the SIFT algorithm to extract keypoint features that are used to evaluate ...
An approach to improve simultaneous localization and mapping in human populated environments
(IEEEBR, 2021)
One task that autonomous mobile robots have to perform in indoor spaces is to construct the map of their environment and report their location and orientation. This process is called Simultaneous Localization and Mapping ...
