New support vector algorithms for multicategorical data applied to real-time object recognition

Silvio Borer

Humans have the ability to learn. Having seen an object we can recognise it later. We can do this because our nervous system uses an efficient and robust visual processing and capabilities to learn from sensory input. On the other hand, designing algorithm ...

Classification of change detection algorithms for object-based applications

Touradj Ebrahimi, Andrea Cavallaro

Change detection is a temporal segmentation tool aiming at identifying changes in image sets or image sequences at two different times. Many change detection algorithms have been proposed over the past decade for the generation of video objects in a wide r ...

PIX-Grid: A Platform for P2P photo exchange

Karl Aberer, Manfred Hauswirth, Philippe Cudré-Mauroux, Anwitaman Datta

The proliferation of digital camera devices (stand-alone or combined with cell phones), new protocols such as MMS and the desire of people to com-municate and share their experience call for new systems to support these needs in new Internet-scale infrastr ...

Using colour to model outliers

Sabine Süsstrunk, David Hasler

Computer vision applications are able to model and reconstruct three dimensional scenes from several pictures. In this work, we are interested in the group of algorithm that register each image with respect to the model and aim at constructing a model of t ...

Motion Detection and Path Planning in Dynamic Environments

Roland Siegwart, Björn Jensen, Roland Philippsen

Motion detection from mobile platforms is a challenging task. It requires precise position information, which is difficult in cluttered dynamic environments. We combine motion detection and position estimation using Expectation Maximization. To reduce the ...

Perspectives on panoramic photography

David Hasler

Digital imaging brings a new set of possibilities to photography. For example, little pictures can be assembled to form a large panorama, and digital cameras are trying to mimic the human visual system to produce better pictures. This manuscript aims at de ...

Color Handling in Panoramic Photography

Sabine Süsstrunk, David Hasler

Nowadays, the ability to create panoramic photographs is included with most of the commercial digital cameras. The principle is to shoot several pictures and stitch them together to build a panorama. To ensure the quality of the final image, the different ...

MPEG-7 CAMERA

Touradj Ebrahimi, Yousri Abdeljaoued, Oscar Divorra Escoda

MPEG-7 camera extends the capabilities of conventional cameras by analyzing its scene in order to generate a contentbased description according to the recently approved MPEG- 7 standard. This gives to the camera a large variety of current and potential app ...
