Linear Complexity Stereo Matching Based on Region Indexing
This paper presents a linear complexity method for real-time stereo matching, in which the processing time is only dependent on the image resolution. Regions along each epipolar l...

All Superlinear Inverse Schemes Are coNP-Hard
How hard is it to invert NP-problems? We show that all superlinearly certified inverses of NP problems are coNP-hard. To do so, we develop a novel proof technique that builds dia...

All Pairings Are in a Group
In this paper, we suggest that all pairings be in a group from an abstract angle. According to our results, we can define some new pairings with short Miller loops and hence speed ...

Some Notes on the Linear Complexity of Sidel'nikov-Lempel-Cohn-Eastman Sequences
We continue the study of the linear complexity of binary sequences, independently introduced by Sidel'nikov and Lempel, Cohn, and Eastman. These investigations were originated...

A generalization of Gram-Schmidt orthogonalization generating all Parseval frames
Given an arbitrary finite sequence of vectors in a finite–dimensional Hilbert space, we describe an algorithm, which computes a Parseval frame for the subspace generated by the...
