Depth map compression via 3D region-based representation

In 3D video, view synthesis is used to create new virtual views between encoded camera views. Errors in the coding of the depth maps introduce geometry inconsistencies in synthesized views. In this paper, a new 3D plane representation of the scene is presented which improves the performance of current standard video codecs in the view synthesis domain. Two image segmentation algorithms are proposed for generating a color and depth segmentation. Using both partitions, depth maps are segmented into regions without sharp discontinuities without having to explicitly signal all depth edges. The resulting regions are represented using a planar model in the 3D world scene. This 3D representation allows an efficient encoding while preserving the 3D characteristics of the scene. The 3D planes open up the possibility to code multiview images with a unique representation.Postprint (author's final draft

Smart data collection for road maintenance

The aim of this project is to automate the recollection of data from roads in a city, with the goal of creating an inventory of traffic signs, traffic lights, road markings and other elements in the road. Thanks to this method it will be possible to attach a camera or a mobile phone to a vehicle and map the road of the entire city with all these objects. In this project, an object detector of the YOLO family will be implemented to solve the task of detecting traffic signs and traffic lights. Through this document , all the techniques and procedures made to obtain the results will be explained, as well as showing some of the predictions that the model has made

Benefits of rIX-FP prophylaxis in patients with Haemophilia B: real-world evidence from a Spanish reference centre

Haemophilia B; pharmacokinetic; Real world evidenceHemofilia B; Farmacocinética; Evidencia del mundo realHemofília B; Farmacocinètica; Evidència del món realStandard FIX prophylaxis for PWHB require frequent injections, which has led to the development of extended half-life products like rIX-FP (albutrepenonacog alfa) that has shown good efficacy in clinical studies. This ambispective study aims to report a real-world experience with rIX-FP in a Spanish centre with PWHB who switched from SHL-FIX or began prophylaxis with rIX-FP. Five PWHB were included in this study, Four PTP switched to rIX-FP with prophylaxis every 7 days whilst one PUP started with an every-14-days regimen. 3 PTPs extended their dosing intervals to every 14 days or every 21 days. In all PTPs, median annualized spontaneous and joint bleeding rates were maintained at 0.00 and median (range) of ABR was 0.92 (0.00–2.77) after switch to rIX-FP. Mean trough level with previous product was 3.68% (SD = 2.06), while it was 7.08% (SD = 3) with all rIX-FP dosing intervals. After switching to rIX-FP, all PTP reduced their annual infusion rate between 50 and 84% and their annual FIX consumption by 61% (59–67%). This is the first reported real-world experience with albutrepenonacog alfa in a small cohort in Spain and demonstrates good bleeding control together with a reduction of the infusion rate, factor consumption and higher through factor level than previous treatment

Floración y turismo en Mallorca y el Baix Segre: Dos casos emblemáticos de imagen de marca turistico-paisajística

In this paper, two consolidated cases of landscape-motivated tourism are described: the winter flowering of almond trees in Mallorca (Balearic Islands) and the spring flowering of temperate fruit trees in the Baix Segre sub-region (Catalonia). The objective is to present a synthetic reconstruction of the historical process of formation of these tree crops, and their constitution as a landscape brand image in both regions, as well as their incorporation into the tourist market under the well-known formula of environmental and cultural tourism. In Mallorca, leisure and tourism practices around flowering operate as an alternative to the 'sun and beach' model, while in Baix Segre they constitute their most important contribution to the rural tourism modality. The scope of the flowering and tourism pair has still been little studied, hence it deserves a study that aims to serve as a basis for future works on the subject.En el presente trabajo se describen dos casos consolidados de turismo de motivación paisajística: la floración invernal de almendros en Mallorca (Islas Baleares) y la floración primaveral de frutales de clima templado en la subcomarca del Baix Segre (Cataluña). El objetivo es presentar una reconstrucción sintética del proceso histórico de formación de estos cultivos arbóreos, y su constitución como imagen de marca paisajística en ambas regiones, así como su incorporación al mercado turístico bajo la conocida fórmula del turismo ambiental y cultural. En Mallorca, las prácticas de ocio y turismo en torno a la floración operan como alternativa al modelo de ‘sol y playa’, mientras que en el Baix Segre constituyen su más importante contribución a la modalidad de turismo rural. El alcance del par floración y turismo ha sido todavía poco estudiado, de ahí que merezca un estudio que pretende servir de base para futuros trabajos sobre el tema
