On the Intractability of Inverting Geometric Distortions in Watermarking Schemes
We examine the problem of watermarking schemes robust against geometric distortions from a complexity theoretic point of view. The main results presented are polynomial time reduct...

Stabilization by Means of Time-varying Hybrid Feedback
In this work characterizations of the notion of non-uniform in time robust global asymptotic output stability for hybrid systems with disturbances are given. Based on the provided ...

Fast and Accurate Text Classification via Multiple Linear Discriminant Projections
Abstract. Support vector machines (SVMs) have shown superb performance for text classification tasks. They are accurate, robust, and quick to apply to test instances. Their only po...

Extracting moving regions from spatial data
We provide an algorithm that can construct a valid moving region from snapshots of a region in time. Our algorithm is robust in the sense that given valid input regions, the gener...

Comparison of CP-OFDM and OFDM/OQAM in Doubly Dispersive Channels
In this paper we compare the performance of cyclic prefix based OFDM (CP-OFDM) systems and OFDM/offset QAM (OFDM/OQAM) systems in doubly dispersive channels, by investigating the...
