Super-resolving multiresolution images with band-independant geometry of multispectral pixels [PDF]

, 2016
A new resolution enhancement method is presented for multispectral and multi-resolution images, such as these provided by the Sentinel-2 satellites. Starting from the highest resolution bands, band-dependent information (reflectance) is separated from ...

Indigenous peoples as sentinels of change in human‐wildlife relationships: Conservation status of mountain goats in Kitasoo Xai'xais territory and beyond

Conservation Science and Practice, 2022
Local people can act as sentinels for change, especially for wildlife populations not monitored by centralized governments. Responding to concern expressed by the Kitasoo Xai'xais (KX) First Nation over a decline in mountain goat (Oreamnos americanus ...

Sentinels in the visual system [PDF]

Frontiers in Behavioral Neuroscience, 2011
The human visual system, like that of other mammals, comprises a multiplicity of par-allel visual pathways of old evolutionary origin that bypass the primary visual cortex (V1; Milner and Goodale, 2006; Tamietto and de Gelder, 2010). We currently know very little about these V1-independent pathways, but it makes sense from an evolu-tionary standpoint ...

A modified sentinel node and occult lesion localization (SNOLL) technique in non-palpable breast cancer. A pilot study [PDF]

, 2015
Background: The spread of mammographic screening programs has allowed an increasing amount of early breast cancer diagnosis. A modern approach to non-palpable breast lesions requires an accurate intraoperative localization, in order to achieve a ...

Evaluation of Semantic Segmentation Methods for Land Use with Spectral Imaging Using Sentinel-2 and PNOA Imagery

Remote Sensing, 2021
Land use classification using aerial imagery can be complex. Characteristics such as ground sampling distance, resolution, number of bands and the information these bands convey are the keys to its accuracy. Random Forest is the most widely used approach
