Fusión automática de imágenes a través de la obtención de sinogramas

Ingeniería e Investigación, 1998
El desarrollo de técnicas de fusión tiene un alto costo computacional y demandan, por el uso que de ellas se da, excelentes resultados. Este trabajo compara la aplicación de dos técnicas de retroproyección (proyección de máxima intensidad y promedio ...

LA FUSIÓN DE IMÁGENES DE TELEDETECCIÓN: UNA AYUDA PARA LA INTERPRETACIÓN DE ENTORNOS URBANOS [PDF]

EGA, 2010
La fusión de imágenes que interesa en la interpretación de entornos urbanos es aquella en la que se une una imagen pancromática (PAN) y otra multiespectral (MS). La PAN aporta una gran resolución espacial pero sólo en color gris mientras que la MS aporta

A Method to Visualize Cell Proliferation of <i>Arabidopsis thaliana</i>: A Case Study of the Root Apical Meristem. [PDF]

Plant Direct
ABSTRACT Plant growth and development rely on a delicate balance between cell proliferation and cell differentiation. The root apical meristem (RAM) of Arabidopsis thaliana is an excellent model to study the cell cycle due to the coordinated relationship between nucleus shape and cell size at each stage, allowing for precise estimation of the cell ...

The anterior perforated substance (APS) revisited: Commented anatomical and imagenological views

Brain and Behavior, Volume 13, Issue 12, December 2023., 2023
Abstract Introduction Since 2002, when we published our article about the anterior perforated substance (APS), the knowledge about the region has grown enormously. Objective To make a better description of the anatomy of the zone with new dissection material added to the previous, to sustain the anatomical analysis of the MRI employing the SPACE ...

3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

A generalizable normalization for assessing plant functional diversity metrics across scales from remote sensing

Methods in Ecology and Evolution, Volume 14, Issue 8, Page 2123-2136, August 2023., 2023
Abstract Remote sensing (RS) increasingly seeks to produce global‐coverage maps of plant functional diversity (PFD) across scales. PFD can be quantified with metrics assessing field or RS data dissimilarity. However, their comparison suffers from the lack of normalization approaches that (1) correct for differences in the number and correlation of ...

Digitizing the coral reef: Machine learning of underwater spectral images enables dense taxonomic mapping of benthic habitats

Methods in Ecology and Evolution, Volume 14, Issue 2, Page 596-613, February 2023., 2023
Abstract Coral reefs are the most biodiverse marine ecosystems, and host a wide range of taxonomic diversity in a complex spatial community structure. Existing coral reef survey methods struggle to accurately capture the taxonomic detail within the complex spatial structure of benthic communities.

A comparative study on deep‐learning methods for dense image matching of multi‐angle and multi‐date remote sensing stereo‐images

The Photogrammetric Record, Volume 37, Issue 180, Page 385-409, December 2022., 2022
Among all stereo matching methods End‐to‐End (E2E) learning methods show that they can achieve the lowest and most frequent minimum errors, however, their performance drastically changes across different test‐sites, which indicates poor generalisation capabilities.

Marketing of luxurious gastronomic experiences on social media: The visual storytelling of luxury hotels

International Journal of Tourism Research, Volume 24, Issue 6, Page 827-838, November/December 2022., 2022
Abstract The role of luxury as a source of tourism experiences is gathering growing attention, with special attention to the foundations of the relationships between gastronomy and social media marketing. Drawing from a visual methodology, this study analyses how luxury hotels (Burj Al Arab, Emirates Palace, St.
