The current design of database drivers – a necessary evil for interacting with a DBMS – imposes undue burdens on those who install, upgrade, and manage database systems and their applications. In this paper, we introduce Drivolution, a new architecture for ...
Classifying materials from their appearance is challenging. Impressive results have been obtained under varying illumination and pose conditions. Still, the effect of scale variations and the possibility to generalise across different material samples are ...
With the help of databases of the Swiss Federal Railways (SBB CFF FFS), statistical analyses are carried out on the lifetime of railway switches (points) and crossings. The expected lifetimes are attributed to different parameters which influence the speed ...
This document presents an overview of the mobile biometry (MOBIO) database. This document is written expressly for the face and speech organised for the 2010 International Conference on Pattern Recognition. ...
One of the main problems of today's ALS is the lack of reliable data quality assessment within or shortly after the airborne survey campaign. The paper presents an in- flight quality monitoring tool that allows assessing the quality of the recorded data "o ...
The following paper shows an approach to measure orientation data of sensors during an airplane flight for traffic data acquisition. This orientation data is necessary for georegistration of any taken aerial images and extracted features. Since an inertial ...
In this paper we evaluate and compare six well-known foreground from background subtraction methods against a standard database. To be able to compare these algorithms objectively, we have chosen three challengeable scenarios from this database. The algori ...
Approximately 25 percent of the budget for the maintenance and renewal of railway tracks –in Switzerland more than a billion Swiss Francs– is used for the switches (points) and crossings (S&C). While in the mean time the budget expenditure for the maintena ...
From image retrieval to image classification, all research shares one common requirement: a good image database to test or train the algorithms. In order to create a large database of images, we set up a project that allowed gathering a collection of more ...
Critical sections in database storage engines impact performance and scalability more as the number of hardware contexts per chip continues to grow exponentially. With enough threads in the system, some critical section will eventually become a bottleneck. ...
