2012 Lecture Notes in Computer Science  
(inliers) lie, to the extent that one can tightly enclose the manifold within the error bounds of a low-dimensional hyperplane for accurate outlier rejection.  ...  We advance the surprising view that for many realistic physical deformations, the error of the mismatches (outliers) usually dwarfs the effects of the curvature of the manifold on which the correct matches  ...  For deformations of 2D image features, it is common to use In Defence of RANSAC for Outlier Rejection in Deformable Registration 5 two separate RBF warps that share the same centres {c k } K k=1 x y →  ...

Deep Neural Networks for Marine Debris Detection in Sonar Images [article]

Matias Valdenegro-Toro
2019 arXiv   pre-print
We also study the effect of sample complexity and object size in many tasks, which is valuable information for practitioners.  ...  This thesis performs a comprehensive evaluation on the use of DNNs for the problem of marine debris detection in FLS images, as well as related problems such as image classification, matching, and detection  ...  The authors experiments show that many false matches are produced in sonar images. RANSAC is applied to discard outliers while fitting a transformation to align both images.  ...
