Multichannel source separation and tracking with phase differences by random sample consensus
… dataset. This data is clustered with the RANdom SAmple Consensus (RANSAC) algorithm in the presence of strong reverberation to simultaneously localize and separate speakers. The remarkable performance of RANSAC is due to its natural tendency to reject outliers. To handle the case of …

Automatic Extraction of Joint Characteristics from Rock Mass Surface Point Cloud Using Deep Learning
… by fitting least-square planes using the Random Sample Consensus (RANSAC). Finally, the joint planes are classified into different joint sets, and the dip direction and dip angle for each set are calculated. The performance of the proposed methodology has been evaluated using a case study. …

Using Random Sampling Consensus (RANSAC) to Detect Errors in Global Navigation Satellite Systems (GNSS) Signals and Data
… phase (TDCP), provide for error reduction. The random sample consensus (RANSAC) method allows for the smoothing of data, even when there are a lot of gross errors present in the data set. The residuals from RANSAC and TDCP were studied to determine if they can be used to detect and identify …

A feature-based fingerprinting scheme robust to desynchronization
… this method to an adapted version of RANSAC (Random Sample Consensus). The fingerprints are embedded securely and invisibly using Spread Transform Dither Modulation (STDM) applied to the intermediate level of a Laplace decomposition of the image. The fingerprints are robust against common …

Uma proposta de metodologia para a extração semi-automática de formas arquitetônicas planas utilizando dados provenientes de laser escaner terrestre
… proposta é baseado no algoritmo RANSAC (RANdom SAmple Consensus) e na triangulação de Delaunay. Os resultados obtidos com a metodologia proposta foram comparados com levantamentos topográficos realizados sobre as mesmas fachadas e os seus resultados avaliados através um teste estatístico. …

Terrain aware tactical motion planning and control algorithms for off-road UGVs in GNSS denied hostile environments
… geometric segmentation techniques such as random sample consensus and inverse ray tracing to differentiate traversable surfaces from obstacles. These representations, encompassing occupancy grids and topographic profiles, account for terrain geometry and surface characteristics, providing a …

Estimated Distributed Near-Field Surface Displacements Using Nascent Mobile Laser Scanning
… a deep neural network, and a customized random sample consensus estimator. A combined least squares adjustment is developed for primitive modeling and change detection for both bi- and multi-temporal lidar time series, and the multi-temporal analysis introduces additional temporal …

Assessing age-height relationship using ICESat-2 and Landsat time series products of southern pines in southeastern region
… of heights with a reciprocal of age using a random sample consensus (RANSAC) model to calculate site indices at base age 25 (years). Our results showed the site index for the region at a base age of 25 years is 20.1 m with a model R2 of 0.91. We compared the ICESat-2-derived site index with …

Registration and categorization of camera captured documents
… in point pattern based registration, like RANdom SAmple Consensus (RANSAC) and Thin Plate Spline-Robust Point Matching (TPS-RPM), to enable registration of cell phone and camera captured documents under non-rigid transformations. Three novel aspects are embedded into the methodology: (i) …

The Application and Analysis of Automated Triangulation of Video Imagery by Successive Relative Orientation
… still include the outliers. Therefore, the Random Sample Consensus (RANSAC) method with the essential matrix was applied to detect only inliers of point pairs. Then relative orientation was performed for this series of video imagery using the coplanarity condition. However, there is no …
