Programme-cadre FENOIR (Figurations de l’environnement nocturne des territoires réunionnais). Rapport d’étape pour le Parc national de La Réunion

2022

Soumise à une importante poussée démographique, l’île de La Réunion a vu sa population urbaine fortement augmenter – passant de 44 % de la population totale en 1975 à 95 % en 2015. Directement corrélée aux formes et dynamiques spatiales de l’urbanisation, l’empreinte lumineuse sur l’île a connu une mutation radicale ces dernières années : son emprise et sa pression ont considérablement augmenté sur l’ensemble du territoire, depuis la côte jusqu’à l’intérieur même du Parc national de La Réunion qui recouvre plus de 76 % du territoire insulaire (42 % pour la zone cœur). Acteur incontournable des enjeux environnementaux sur l’île, le Parc national a mené très tôt des actions autour des effets …

Fast and Robust Face Detection on a Parallel Optimized Architecture implemented on FPGA

2009

In this paper, we present a parallel architecture for fast and robust face detection implemented on FPGA hardware. We propose the first implementation that meets both real-time requirements in an embedded context and face detection robustness within complex backgrounds. The chosen face detection method is the Convolutional Face Finder (CFF) algorithm, which consists of a pipeline of convolution and subsampling operations, followed by a multilayer perceptron. We present the design methodology of our face detection processor element (PE). This methodology was followed in order to optimize our implementation in terms of memory usage and parallelization efficiency. We then built a parallel arch…

Design of a Real-time face detection parallel architecture using High-Level Synthesis

2008

Abstract We describe a High-Level Synthesis implementation of a parallel architecture for face detection. The chosen face detection method is the well-known Convolutional Face Finder (CFF) algorithm, which consists of a pipeline of convolution operations. We rely on dataflow modelling of the algorithm and we use a high-level synthesis tool in order to specify the local dataflows of our Processing Element (PE), by describing in C language inter-PE communication, fine scheduling of the successive convolutions, and memory distribution and bandwidth. Using this approach, we explore several implementation alternatives in order to find a compromise between processing speed and area of the PE. We …

Multiple modular very long instruction word processors based on field programmable gate arrays

2007

Modern field programmable gate array (FPGA) chips, with their large memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high-density FPGAs, it is now possible to implement a high-performance very long instruction word (VLIW) processor core in an FPGA. This paper describes research results about enabling the DSP TMS320 C6201 model for real-time image processing applications by exploiting FPGA technology. We present a modular DSP C6201 VHDL model with a variable instruction set. We call this new development a minimum mandatory modules (M3) approach. Our goals are to keep the flexibility of DSP in order to shor…

Au sein du CNRS, un Observatoire de l’environnement nocturne pour accompagner la territorialisation de la lutte contre la pollution lumineuse

2022

National audience; Jusqu’à présent, les politiques de préservation de l’environnement nocturne peinent à saisir l’ensemble des effets négatifs de la lumière artificielle nocturne (ALAN). La question de la qualité de l’environnement nocturne n’est ainsi que partiellement traitée. D’une part, les enjeux liés à l’efficience énergétique des systèmes techniques d’éclairage et à la qualité du ciel étoilé occultent quasi systématiquement les enjeux écologiques et sanitaires de la préservation de l’obscurité. D’autre part, un fossé considérable persiste entre des solutions de mitigation technique à l’échelle locale et la mise en œuvre, à des échelles plus larges, de zonages construits par et pour d…

The chosen face detection method is the well-known convolutional face finder (CFF) algorithm, which consists in a pipeline of convolutions and subsampling operations. Our goal is to define a parallel architecture able to process efficiently this algorithm. We present a dataflow based architecture algorithm adequation (AAA) methodology implemented using the SynDEx software, in order to find the best compromise between the processing power and functionality requirement of each processor element (PE), and the efficiency of algorithm parallelization. We describe a first implementa…
