Quasi-Euclidean uncalibrated epipolar rectification
This paper deals with the problem of epipolar rectification in the uncalibrated case. First the calibrated (Euclidean) case is recognized as the ideal one, then we observe that in...

A Unification Framework for Tree and Block Wavelet Encoders
Wavelet transform coefficient encoders are broadly categorized as depending on correlations: across sub-bands through a zerotree, or within sub-bands through a block quad-tree. Th...

Multi-resolution Source Coding Using Entropy Constrained Dithered Scalar Quantization
In this paper, we build multi-resolution source codes using entropy constrained dithered scalar quantizers. We demonstrate that for n-dimensional random vectors, dithering followe...

Event-Clock Visibly Pushdown Automata
Abstract. We introduce the class of event-clock visibly pushdown automata (ECVPAs) as an extension of event-clock automata. The class of ECVPAs, on one hand, can model simple real-...

Toward a Compositional Theory of Leftist Grammars and Transformations
Leftist grammars [Motwani et al., STOC 2000] are special semi-Thue systems where symbols can only insert or erase to their left. We develop a theory of leftist grammars seen as wor...
