Speckle reduction in Synthetic Aperture Radar (SAR) images is a crucial challenge for effective image analysis and interpretation remote sensing applications. This study proposes novel deep learning-based approach using autoencoder architectures SAR despeckling, incorporating of variance (ANOVA) hyperparameter optimization. The research addresses significant gaps existing methods, such as the lack rigorous model evaluation absence systematic optimization techniques learning models...
Lower-limb robotic prosthetics can benefit from context awareness to provide comfort and safety the amputee. In this work, we developed a terrain identification surface inclination estimation system for prosthetic leg using visual inertial sensors. We built dataset which images with high sharpness are selected IMU signal. The used is also computed simultaneously. With such information, control of robotized be adapted changes in its surrounding.
This paper presents a methodology to detect the coastal erosion and progradation effects in ‘Atrato River’ delta, located Gulf of Urabá Colombia, using SAR (Synthetic Aperture Radar) images. Erosion is physical–mechanical loss soil that affects its functions ecosystem services while producing reduction productive capacity. Progradation deposition layers basinward direction moving coastward. Other studies have investigated these two phenomena optical images, encountering difficulties due...
This article presents a dataset of thermal and visible aerial images the same flat scene at Melendez campus Universidad del Valle, Cali, Colombia. The were acquired using an UAV equipped with either or camera. is useful for testing techniques improvement, registration fusion multi-modal multi-spectral images. consists 30 their metadata, 80 georeferenced orthoimage. metadata related to every image contains WGS84 coordinates allocating Also, homography matrices between orthoimage are included...
This paper presents a methodology to detect the erosion and progradation effects in Atrato river delta, located Gulf of Urabá Colombia using SAR (Synthetic Aperture Radar) data. Other authors have studied this area by optical images, encountering difficulties given persistent presence clouds region. imagery is rescaled, despeckled, composed, classified, registered processed obtain heatmap that shows overall changes during eight years (2016–2023) one single image. Since technology uses...
En los últimos años, uno de principales problemas en Colombia es la contaminación ambiental debido al crecimiento población y industrialización. La afecta a las grandes ciudades, perjudicando el medio ambiente salud humana. Es por ello que se presenta una metodología para análisis Medellín, usando técnicas percepción remota, imágenes Landsat 7 8 variables calidad del aire. está compuesta cuatro etapas: i. Preprocesamiento imágenes, ii. Procesamiento cálculo índices temperatura superficie...
La evaluación del deterioro de las vías en Colombia se realiza por medio inventarios manuales e inspecciones visuales. Los métodos estado adoptados el INVIAS (Instituto Nacional Vías) son VIZIR (Visión Inspection Zones et Itinéraires Á Risque) y PCI (Paviment Condition Index). Estos determinan la gravedad daño pavimento flexible rígido; sin embargo, pueden ser tediosos, subjetivos requieren experiencia un evaluador, lo que evidencia necesidad desarrollar metodologías vías. Este documento...
Las interfaces cerebro-computadora no invasivas basadas en EEG de imaginación motora (miBCI) prometen restaurar efectivamente el control motor a pacientes con discapacidades motoras, por ejemplo, aquellos lesión la médula espinal (LME). Sin embargo, todavía es necesario investigar las miBCI, fines rehabilitación, para este tipo que utilizan dispositivos adquisición señales bajo costo, tales como Emotiv EPOC. En trabajo, se describe detalle y comparan diez arquitecturas miBCI información...
We present a comparative study about stereoscopic reconstruction process focused in modelling for parallel axis cameras. used two classical models and one based on Artificial Neural Networks the system. Then we root mean square of distances between point coordinates calculated from images measured calibration pattern to evaluate accuracy each model. compared Networks. By comparing confidence interval every obtained model observed that Silven Heikkila [1] shows average errors 1.0 cm, however...
This article presents a dataset of raw microscopic images the prefrontal cortex from wistar rat tissues, after an induced stroke, stained with NeuN antibody. The were captured using microscope equipped digital camera. is useful for testing techniques improvement, registration, and stitching to generate high-resolution image full reconstruction tissues. Besides, this can be used assess neuronal brain ischemic event. contains 1370 20x magnification 36 (Hierarchical Data Format version 5) hdf5...
