Document images are degraded through bilevel processes such as scanning, printing, and photocopying. The resulting image degradations can be categorized based either on observable degradation features or on degradation model parameters. The degradation features can be related mathematically to model parameters. In this paper we statistically compare pairs of populations of degraded character im...

Scene perception is a fundamental aspect of vision. Humans are capable of analyzing behaviorally-relevant scene properties such as spatial layouts or scene categories very quickly, even from low resolution versions of scenes. Although humans perform these tasks effortlessly, they are very challenging for machines. Developing methods that well capture the properties of the representation used by...

In this paper, we describe an efficient method for audio matching which performs effectively for a wide range of classical music. The basic goal of audio matching can be described as follows: consider an audio database containing several CD recordings for one and the same piece of music interpreted by various musicians. Then, given a short query audio clip of one interpretation, the goal is to ...

he Artificial Visual System (AVS) (Figure 1) ~mputational framework for computer vision. [1] n AVS convolves an image with a series of D mtial filters, yielding a series of D filtered aages. While any set of filters can be applied in ds way, families of filters can be designed to .~oduce a compact, task-specific decomposition or a meral, task-independent decomposition of the aage. The filter se...

The talk will show how the disambiguation of discourse connectives can improve their automatic translation. Connectives are a class of frequent functional lexical items that play an important role in text readability and coherence. Longer-range context is taken into account to learn the signaled rhetorical relations. The labels obtained from a discourse connective classifier are then integrated...

We use the Margin Infused Relaxed Algorithm of Crammer et al. to add a large number of new features to two machine translation systems: the Hiero hierarchical phrasebased translation system and our syntax-based translation system. On a large-scale ChineseEnglish translation task, we obtain statistically significant improvements of +1.5 B and +1.1 B, respectively. We analyze the impact of ...

This presentation analyses the histological types, relative incidences, age, sex and anatomical distributions of one hundred and seventy-nine biopsy proven tumors of the spinal canal from a general hospital in Iran. Particular attention is paid to differences in the relative incidence of these tumors compared with that in various published reports and the statistics from several eastern co...
