Available in PDF, EPUB and Kindle. Book excerpt: LE CADRE DE CETTE THESE EST CELUI DU CODAGE D'IMAGES BASEES REGION. DEUX THEMES MAJEURS SONT ETUDIES : LA TRANSFORMATION EN SOUS-BANDES BASEE REGION ET L'INDEXATION DANS LE CONTEXTE DE LA QUANTIFICATION VECTORIELLE. LES TRANSFORMATIONS SOUS-BANDES BASEES REGIONS DEVELOPPEES S'APPLIQUENT A DES REGIONS DE FORMES ARBITRAIRES EN CONSERVANT L'ECHANTILLONNAGE CRITIQUE. ELLES SONT INDEPENDANTES DE LA LOCALISATION DE LA REGION DANS L'IMAGE ET LE TRAITEMENT DE L'“INTERIEUR” D'UNE REGION EST INDEPENDANT DE SA FORME. DANS CETTE OPTIQUE UNE TRANSFORMATION EN “ONDELETTES SUR L'INTERVALLE” EST PRESENTEE. AFIN DE POUVOIR UTILISER DES BANCS DE FILTRES VARIANT PAR DECALAGE, UNE NOUVELLE METHODE DE FACTORISATION EST DEVELOPPEE : ELLE PERMET DE SYNTHETISER DES TRANSFORMATIONS ORTHOGONALES BASEES SUR L'INTERVALLE D'UNE MANIERE SIMPLE A PARTIR DES TRANSFORMATIONS “CLASSIQUES”. LE PROBLEME “MAJEUR” ACTUEL DE LA QUANTIFICATION VECTORIELLE EST LA TAILLE DES DICTIONNAIRES NECESSAIRE POUR L'INDEXATION. IL EST PROPOSE UNE METHODE COMPLETE D'INDEXATION, N'UTILISANT PAS DE DICTIONNAIRE, DE TRES FAIBLE COUT DE CALCUL, S'APPLIQUANT A LA PLUPART DES RESEAUX UTILISES EN QUANTIFICATION. ELLE EST PARTICULIEREMENT BIEN ADAPTEE POUR DES SOURCES GAUSSIENNES OU LAPLACIENNES QUI MODELISENT COURAMMENT LES SOUS-BANDES EN IMAGE.

Download or read book Renewing Local Planning to Face Climate Change in the Tropics written by Maurizio Tiepolo and published by Springer. This book was released on 2017-07-05 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book aims to inspire decision makers and practitioners to change their approach to climate planning in the tropics through the application of modern technologies for characterizing local climate and tracking vulnerability and risk, and using decision-making tools. Drawing on 16 case studies conducted mainly in the Caribbean, Central America, Western and Eastern Africa, and South East Asia it is shown how successful integration of traditional and modern knowledge can enhance disaster risk reduction and adaptation to climate change in the tropics. The case studies encompass both rural and urban settings and cover different scales: rural communities, cities, and regions. In addition, the book looks to the future of planning by addressing topics of major importance, including residual risk integration in local development plans, damage insurance and the potential role of climate vulnerability reduction credits. In many regions of the tropics, climate planning is growing but has still very low quality. This book identifies the weaknesses and proposes effective solutions.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Download or read book The Forests of the Congo Basin written by Carlos de Wasseige and published by . This book was released on 2012 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2010 State of the Forest report (SOF) benefited from financial support from the European Union, the United States, Germany, France and UNESCO. It represents the collaborative effort of over 100 individuals from a diversity of institutions and the forestry administrations of the Central African countries. The SOF process began with the selection and definition of indicators relevant to monitoring the state of forests in Central Africa. The indicators are structured around three thematic areas: (i) forest cover; (ii) management of production forests; and (iii) conservation and biodiversity. They are presented in a hierarchical structure at the regional, national and management unit (i.e. logging concessions and protected areas) levels. The indicators were vetted by a representative panel of stakeholders of forest management in Central Africa. The indicators are used to guide an annual data collection process carried out between April and August by national groups of four to ten individuals working within the forestry administrations. The data reported on in the 2010 SOF were primarily collected in 2009 and 2010. Results were validated in national workshops attended by government officials as well as representatives of environmental NGOs, the private sector and development projects. The data provided an important basis for the authors of the 11 chapters of the 2010 SOF, which were under the coordination of a scientific committee of international renown. A final workshop was held 29-30 March, 2011 in Douala to review a draft report. Following amendments based on comments from a wide audience of experts the final layout was completed.

Download or read book Local Approximation Techniques in Signal and Image Processing written by Vladimir I︠A︡kovlevich Katkovnik and published by SPIE-International Society for Optical Engineering. This book was released on 2006 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a wide class of novel and efficient adaptive signal processing techniques developed to restore signals from noisy and degraded observations. These signals include those acquired from still or video cameras, electron microscopes, radar, X-rays, or ultrasound devices, and are used for various purposes, including entertainment, medical, business, industrial, military, civil, security, and scientific. In many cases useful information and high quality must be extracted from the imaging. However, often raw signals are not directly suitable for this purpose and must be processed in some way. Such processing is called signal reconstruction. This book is devoted to a recent and original approach to signal reconstruction based on combining two independent ideas: local polynomial approximation and the intersection of confidence interval rule.
