OMECA: Optimization of Modular Embedded Computer-vision Architectures





Modern cameras imitate interaction between human eyes and brain. They can process and transmit visionary patterns timely. Timely transmission of these patterns can be used to detect events of interest automatically.

The fundamental research objective of OMECA project is to investigate the feasibility of a camera platform to process and transmit patterns. This involves two resources, viz, camera hardware and network. Hence this objective is sought by establishing the predictability of camera hardware architecture and network. A feasible algorithm can interleave processing and transmission so as to generate an optimal schedule to obtain functional requirement of timeliness. To this end, the System Architecture and Networking (SAN) group at TU/e contributes to this project by modeling reliability, predictability and performance of these two resources; thus offering an integrated system architecture. SAN is part of an OMECA consortium which consists of three SMEs (Prodrive, Gatsometer, and Cyclomedia), and two Universities (LIACS and TU/e).

SAN contributions

a.      Performance framework

·         Development of a performance framework for resource sharing and reservations on wireless broadcast networks. An IEEE 802.11e controlled wireless channel is used to asses and then model the behavior of multiple competing streams with different QoS requirements. The assessment was done by scheduling these streams and deriving their QoS properties, which are: frequency of access, share, delay and reliability;

·         The framework allows a tradeoff analysis between different MAC parameters and QoS properties.


b.      Software tools

·         An analytical model solver: XcL

·         A simulator: GRADE
