Video Text Recognition Based on Markov Random Field and Grayscale Consistency Constraint

A method for segmenting and recognizing text embedded in video and images is proposed in this paper. In the method, multiple segmentation hypotheses of text image are first generated based on a MRF model. Background regions in each hypothesis are then remo ...

Text Segmentation and Recognition in Complex Background Based on Markov Random Field

Hervé Bourlard, Jean-Marc Odobez, Datong Chen

In this paper we propose a method to segment and recognize text embedded in video and images. We modelize the gray level distribution in the text images as mixture of gaussians, and then assign each pixel to one of the gaussian layer. The assignment is bas ...

Calculation of geological uncertainties associated with 3-D geological models

Ian Pomian-Srzednicki

3-D geological models are built with data collected in the field such as boreholes, geophysical measurements, pilot shafts or geological mapping. Unfortunately, these data are always limited in number. It implies that geological information is sparse and s ...

Markovian Term Structure Models in Discrete Time

Damir Filipovic

In this article we discuss Markovian term structure models in discrete time and with continuous state space. More precisely we are concerned with the structural properties of such models if one has the Markov property for a part of the forward curve. We in ...

Identifiability and identification of chaotic systems based on adaptive synchronization

This paper deals with the problem of synchronization of chaotic systems when the driven (slave, receiver) system has the same structure as the master (driving, emitter) system but its parameters are unknown. It is shown that the concept of synchronization ...

Modélisation markovienne du trafic dans les réseaux de communication

The principal question we address in this work is the following: "Is Markov modelling appropriate to analyse data networks?". We will conclude that it is. The motivation for this question comes from the work of a research team at Bellcore who argue that th ...

Numerical experiments on hydrodynamic dispersion in network models of natural media

Andrea Rinaldo

Dispersion of tracers in random network is considered. Network models of natural media here include: i) channel networks, possibly of fractal nature, whose geometrical characters have recently attracted interest in hydrological literature; and ii) network ...
