Robust finger tracking for wearable computer interfacing

Ali H. Sayed

Key to the design of human-machine gesture interface applications is the ability of the machine to quickly and efficiently identify and track the hand movements of its user. In a wearable computer system equipped with head-mounted cameras, this task is ext ...

Combining Neural Gas and Learning Vector Quantization for Cursive Character Recognition

Alessandro Vinciarelli

This paper presents a cursive character recognizer, a crucial module in any Cursive Script Recognition system based on a segmentation and recognition approach. The character classification is achieved by combining the use of Neural Gas (NG) and Learning Ve ...

Higher Order Autocorrelations for Pattern Classification

Jean-Philippe Thiran, Vlad Popovici

The use of higher-order local autocorrelations as features forpattern recognition has been acknowledge since many years, but their applicability was restricted to relatively low orders (2 or 3) and small local neighborhoods, due to combinatorial increase i ...

A new normalization technique for cursive handwritten words

Alessandro Vinciarelli

This paper presents new techniques for slant and slope removal in cursive handwritten words. Both methods require neither heuristics nor parameter tuning. This avoids the heavy experimental effort required to find the optimal configuration of a parameter s ...

A new normalization technique for cursive handwritten words

Alessandro Vinciarelli

This paper presents new techniques for slant and slope removal in cursive handwritten words. Both new methods make no use of heuristics and no manual parameter tuning is needed. This avoids the heavy experimental effort required to find the optimal configu ...

Automatic segmentation and measurement of axones in microscopic images

Olivier Cuisenaire

We propose a method for the automatic segmentation, recognition and measurement of neuronal fibers in microscopic images of nerves. This permits a quantitative analysis of the distribution of the areas of the fibers, while nowadays such morphometrical meth ...

Conferring human action recognition skills to life-like agents

Daniel Thalmann, Ronan Boulic

Most of today's virtual environments are populated with some kind of autonomous life-like agents. Such agents follow a preprogrammed sequence of behaviours that excludes the user as a participating entity in the virtual society. In order to make inhabited ...

Direct 3D interaction with Smart Objects

Daniel Thalmann

Performing 3D interactions with virtual objects easily becomes a complex task, limiting the implementation of larger applications. In order to overcome some of these limitations, the paper describes a framework where the virtual object aids the user to acc ...

On Spatial Database Integration

Stefano Spaccapietra, Christine Parent

This paper investigates the problems that arise when application requirements command that autonomous spatial databases be integrated into a federated one. The paper focuses on the most critical issues raised by the integration of databases of different sc ...

Extension of the generalized multipole technique to anisotropic medias

Olivier Martin

This paper presents an extension of the generalized multipole technique (GMT) for 2D anisotropic scatterers. New expansions similar to the Bessel multipole expansion are derived for arbitrary anisotropic media. Numerical simulations prove the accuracy and ...
