A new enhancement of ransac, the locally optimized ransac (lo-ransac), is introduced. It has been observed that, to find an optimal solution (with a given probability), the number of samples drawn in ransac is significantly higher than predicted from the mathematical model.

Performance Evaluation of RANSAC Family
Procedings of the British Machine Vision Conference 2009, 2009RANSAC (Random Sample Consensus) has been popular in regression problem with samples contaminated with outliers. It has been a milestone of many researches on robust estimators, but there are a few survey and performance analysis on them. This paper categorizes them on their objectives: being accurate, being fast, and being robust.

Hierarchical RANSAC-Based Rotation Averaging
IEEE Signal Processing Letters, 2020In this letter, we present a novel rotation averaging pipeline, which is performed in a hierarchical manner. Unlike the traditional rotation averaging methods which focus on designing robust loss function to get rid of the impacts of the relative rotation outliers, here the outliers are detected and filtered by leveraging the well-known robust model ...

DL-RANSAC: An Improved RANSAC with Modified Sampling Strategy Based on the Likelihood
2019 IEEE 4th International Conference on Image, Vision and Computing (ICIVC), 2019This paper intends to improve the RANSAC by introducing new sampling method which provides prior knowledge of random population before selecting the hypothesis set. In traditional RANSAC algorithm, a minimal set of samples are chosen randomly from the population containing uneven noise and iteration continues until the desired model is found. Ambiguity

A probabilistic analysis of a common RANSAC heuristic
Machine Vision and Applications, 2018Random Sample Consensus (RANSAC) is an iterative algorithm for robust model parameter estimation from observed data in the presence of outliers. First proposed by Fischler and Bolles back in 1981, it still is a very popular algorithm in the computer vision community.

Image denoising using RANSAC and compressive sensing
Multimedia Tools and Applications, 2022Image denoising is a vital image processing phase aiming to improve the quality of images and to make them more informative. In this paper, we propose a blind denoising approach for removing the outliers (impulsive disturbances) from digital images, by combining the random sample consensus (RANSAC) and compressive sensing (CS) principles.

RANSAC-SVM for large-scale datasets
2008 19th International Conference on Pattern Recognition, 2008Support Vector Machines (SVMs), though accurate, are still difficult to solve large-scale applications, due to the computational and storage requirement. To relieve this problem, we propose RANSAC-SVM method, which trains a number of small SVMs for randomly selected subsets of training set, while tuning their parameters to fit SVMs to whole training ...

Efficient particle filtering using RANSAC with application to 3D face tracking
Image and Vision Computing, 2006 Particle filtering is a very popular technique for sequential state estimation. However, in high-dimensional cases where the state dynamics are complex or poorly modeled, thousands of particles are usually required for real applications.

DT-RANSAC: A Delaunay Triangulation Based Scheme for Improved RANSAC Feature Matching
2013The main objective in content-based image retrieval is to find images similar to a query image in an image collection. Matching using descriptors computed from regions centered at local invariant interest points (keypoints) have become popular because of their robustness to changes in viewpoint and occlusion.
