Surface projection for mixed pixel restoration [PDF]

open access: yes2009 24th International Conference Image and Vision Computing New Zealand, 2009
Amplitude modulated full-field range-imagers are measurement devices that determine the range to an object simultaneously for each pixel in the scene, but due to the nature of this operation, they commonly suffer from the significant problem of mixed ...

Study on the Effect of Surface Roughness on the Spectral Unmixing of Mixed Pixels

open access: yesJournal of Spectroscopy, 2020
In the spectrum measurement experiment, the roughness of the object surface is an essential factor that cannot be ignored. In this experiment, a group of mixed pixel samples with different mixing ratios were designed, and these samples were printed on ...

Research on rice acreage estimation in fragmented area based on decomposition of mixed pixels [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Rice acreage estimation is a key aspect to guarantee food security and also important to support government agricultural subsidy system. In this paper, we explored a sophisticated method to improve rice estimation accuracy at county scale and we ...

The making and evaluation of Picts and Pixels : mixed exhibiting in the real and the unreal [PDF]

open access: yes, 2018
Museums publicly display collections in a physical space to relay narratives and concepts to their audiences. Progressive technologies in an exhibition can bring in varying demographics and gather higher footfall for a museum as well as present digital ...

Estimating daily evapotranspiration based on a model of evaporative fraction (EF) for mixed pixels [PDF]

open access: yesHydrology and Earth System Sciences, 2019
Currently, applications of remote sensing evapotranspiration (ET) products are limited by the coarse resolution of satellite remote sensing data caused by land surface heterogeneities and the temporal-scale extrapolation of the instantaneous latent heat ...

Improved Pansharpening with Un-Mixing of Mixed MS Sub-Pixels near Boundaries between Vegetation and Non-Vegetation Objects

open access: yesRemote Sensing, 2016
Pansharpening is an important technique that produces high spatial resolution multispectral (MS) images by fusing low spatial resolution MS images and high spatial resolution panchromatic (PAN) images of the same area.

Global Land Cover Heterogeneity Characteristics at Moderate Resolution for Mixed Pixel Modeling and Inversion

open access: yesRemote Sensing, 2018
Spatial heterogeneity is present in the land surface at every scale and is one of the key factors that introduces inherent uncertainty into simulations of land surface processes and parameter retrieval based on remotely sensed data.

Mixed pixel analysis and assessment for flood mapping

open access: yes, 2014
The most difficult operation in flood inundation mapping using optical flood images is to map the ‘wet’ areas where trees and houses are partly covered by water.

Remote sensing algorithm for surface evapotranspiration considering landscape and statistical effects on mixed pixels [PDF]

open access: yesHydrology and Earth System Sciences, 2016
Evapotranspiration (ET) plays an important role in surface–atmosphere interactions and can be monitored using remote sensing data. However, surface heterogeneity, including the inhomogeneity of landscapes and surface variables, significantly ...
