RASL: Robust Alignment by Sparse and Low-rank Decomposition for Linearly Correlated Images

by Yigang Peng, Arvind Ganesh, John Wright, Wenli Xu, Yi Ma , 2010
"... This paper studies the problem of simultaneously aligning a batch of linearly correlated images despite gross corruption (such as occlusion). Our method seeks an optimal set of image domain transformations such that the matrix of transformed images can be decomposed as the sum of a sparse matrix of ..."

with guaranteed fast convergence. We verify the efficacy of the proposed robust alignment algorithm with extensive experiments with both controlled and uncontrolled real data, demonstrating higher accuracy and efficiency than existing methods over a wide range of realistic misalignments and corruptions.

Robust Alignment of Presentation Videos with Slides

by Xiangyu Wang, Mohan Kankanhalli
"... Abstract. Many presentations consisting of video, audio and slides are being recorded for wider dissemination purposes. Video slide alignment is necessary for efficient review and hence has attracted much attention. However, the recorded video style varies greatly because of different capturing syst ..."

Multiple sequence alignment with the Clustal series of programs

by Ramu Chenna, Hideaki Sugawara, Tadashi Koike, Rodrigo Lopez, Toby J. Gibson, Desmond G. Higgins, Julie D. Thompson - Nucleic Acids Res , 2003
"... The Clustal series of programs are widely used in molecular biology for the multiple alignment of both nucleic acid and protein sequences and for preparing phylogenetic trees. The popularity of the programs depends on a number of factors, including not only the accuracy of the results, but also the ..."

Approximately Global Optimization for Robust Alignment of Generalized Shapes

by Hongsheng Li, Student Member, Tian Shen, Student Member, Xiaolei Huang
"... Abstract—In this paper, we introduce a novel method to solve shape alignment problems. We use gray-scale “images ” to represent source shapes, and propose a novel two-component Gaussian Mixture (GM) distance map representation for target shapes. This asymmetric representation is a flexible image-bas ..."

evaluated and compared with those of some state-of-the-art methods. Extensive experiments and comparison performed on generalized 2D and 3D shape data demonstrate the robustness and effectiveness of the method. Index Terms—Shape alignment, point registration, matching, distance transform, particle swarm

Robust Alignment of Transmission Electron Microscope Tilt Series

by Sami S. Brandt, Ulrike Ziese
"... In this paper, we propose a novel method for auto-matic, feature-based alignment of transmission electron mi-croscope images that is needed for computing 3D recon-structions in electron tomography. The proposed method, termed as trifocal alignment, is more accurate than the pre-vious markerless meth ..."

Articulated Shape Matching by Robust Alignment of Embedded Representations

by Diana Mateus, Fabio Cuzzolin, Radu Horaud, Edmond Boyer
"... In this paper we propose a general framework to solve the articulated shape matching problem, formulated as finding point-to-point correspondences between two shapes represented by 2-D or 3-D point clouds. The original pointsets are embedded in a spectral representation and the actual matching is ca ..."

orthogonal transformation that aligns the two shape embeddings. Relying on the model based clustering formalism, we propose a probabilistic formulation which casts the matching into an EM algorithm. Outliers are properly handled by the algorithm and a simple strategy is adopted to initialize it. Experiments

Efficient and Robust Alignment of Unsynchronized Video Sequences

by Georgios D. Evangelidis, Christian Bauckhage
"... Abstract. This paper addresses the problem of aligning two unsynchronized video sequences. We present a novel approach that allows for temporal and spatial alignment of similar videos captured from independently moving cameras. The goal is to synchronize two videos of a scene such that changes betwe ..."
