Analysis and design of a subtitling system for ambient intelligence environments

The development of ubiquitous applications for ambient intelligence environments needs to also take into account some usability and accessibility issues in order to ensure a proper user experience and to overcome the existing content access barriers. A proper access to video subtitles, for instance, is not always available due to the technical limitations of traditional video packaging, transmission and presentation. New Web standards enable more featured applications with better multi-platform definition, so they are suitable for building ubiquitous applications for ambient intelligence environments. This work presents a video subtitling system that enables the customization and adaptation of subtitles. The benefits of Web applications compared with device-specific native applications for building the solution as well as its current platform support are analyzed. Finally, three different application use cases are presented

Evaluation of emerging audio description systems for broadcast TV

Following EU directives on Media Access and Ambient Assisted Living, the broadcasting industry needs to introduce new services in order to guarantee access to all citizens. The article and its conclusions are part of the EU project DTV4ALL, which focuses on some possible broadcasting scenarios for achieving barrier - free television for those with visual impairments. Five enhanced Audiodescription (AD) scenarios were proposed and evaluated: 1) Live streaming Internet TV with AD, 2) AD reception in a group situation, 3) Video on demand over aset - top - box , 4) Video on PC and 5) Podcasts. User evaluation concerning usefulness, quality and usability of the services was assessed using questionnaires. Results of the user evaluation show that not only are AD emerging services technically viable but they are also positively rated by users. Implementation of these services will provide improved access to content, making TV accessible for all

Performance analysis techniques for multi-soft-core and many-soft-core systems

Multi-soft-core systems are a viable and interesting solution for embedded systems that need a particular tradeoff between performance, flexibility and development speed. As the growing capacity allows it, many-soft-cores are also expected to have relevance to future embedded systems. As a consequence, parallel programming methods and tools will be necessarily embraced as a part of the full system development process. Performance analysis is an important part of the development process for parallel applications. It is usually mandatory when you want to get a desired performance or to verify that the system is meeting some real-time constraints. One of the usual techniques used by the HPC community is the postmortem analysis of application traces. However, this is not easily transported to the embedded systems based on FPGA due to the resource limitations of the platforms. We propose several techniques and some hardware architectural support to be able to generate traces on multiprocessor systems based on FPGAs and use them to optimize the performance of the running applications

Flujo de diseño asíncrono con la biblioteca DCVSL_LIB para ES2 ECPD10

En el presente trabajo se pretende abordar la metodología a seguir durante el flujo de diseño de un circuito asíncrono orientado a prestaciones, utilizando la biblioteca DCVSL_LIB para aplicaciones asíncronas que hemos desarrollado. Este proceso se aplicará desde un nivel semicustom. La concepción de los algoritmos del sistema se desarrollaran desde una metodología top-down, dadas las restricciones que por construcción debe contener un control asíncrono. Mientras que aspectos tales como el procesado del flujo de datos y control sobre el datapath se aplicaran con una jerarquía botton-up, facilitando la concepción de circuitos asíncronos sencillos y de elevadas prestaciones a partir de soluciones arquitecturales conocidas.Postprint (published version

Low-power pedestrian detection system on FPGA

Pedestrian detection is one of the key problems in the emerging self-driving car industry. In addition, the Histogram of Gradients (HOG) algorithm proved to provide good accuracy for pedestrian detection. Many research works focused on accelerating HOG algorithm on FPGA(Field-Programmable Gate Array) due to its low-power and high-throughput characteristics. In this paper, we present an energy-efficient HOG-based implementation for pedestrian detection system on a low-cost FPGA system-on-chip platform. The hardware accelerator implements the HOG computation and the Support Vector Machine classifier, the rest of the algorithm is mapped to software in the embedded processor. The hardware runs at 50 Mhz (lower frequency than previous works), thus achieving the best pixels processed per clock and the lower power design
