Splat-based surface reconstruction from defect-laden point sets
We introduce a method for surface reconstruction from point sets that is able to cope with noise and outliers. First, a splat-based representation is computed from the point set. A robust local 3D RANSAC-based procedure is used to filter the point set for outliers, then a local jet surface – a lowdegree surface approximation – is fitted to the inliers. Second, we extract the reconstructed surfa...
متن کاملAn Improved RANSAC homography Algorithm for Feature Based Image Mosaic
In this paper, we proposed a new feature based image mosaic algorithm. The improved RANSAC homography algorithm based on the modified media flow filter, to detect wrong matches for improving the stability of the normal RANSAC homography algorithm. The method improved the local registration between neighboring images. Experiments and Statistical Analysis show that our mosaic method is robust. Ke...
متن کاملPoint-based registration of high-resolution histological slices for navigation purposes in virtual microscopy
Automatic registration methods for histological images in virtual microscopy are presented. Point-based approaches with outlier filtering by RANSAC and multibody factorization are investigated. The algorithms are tested on high-resolution biopsy images of the gastrointestinal tract. Quantitative evaluation is performed at different resolution levels. The results reveal the superiority of Harris...
متن کاملEfficient Video Panoramic Image Stitching Based on an Improved Selection of Harris Corners and a Multiple-Constraint Corner Matching
Video panoramic image stitching is extremely time-consuming among other challenges. We present a new algorithm: (i) Improved, self-adaptive selection of Harris corners. The successful stitching relies heavily on the accuracy of corner selection. We fragment each image into numerous regions and select corners within each region according to the normalized variance of region grayscales. Such a se...
متن کاملRegistration of Brain Medical Images Based on SURF Algorithm and R-RANSAC Algorithm
This paper proposes a matching method for medical image registration, which combined with SURF (Speeded up Robust Features) algorithm and the improved R-RANSAC (the Randomized of Random Sample Consensus) algorithm. Firstly, this algorithm extracts featured points with SURF algorithm from images and matches similar featured points with Euclidean distance. Secondly, the RRANSAC algorithm is used ...
