Sub-Pixel Mapping Based on MAP Model and Spatial Attraction Theory for Remotely Sensed Image
IEEE Access, 2017 There are a lot of mixed pixels in the remotely sensed imagery, which can seriously limit the utility of classification. Sub-pixel mapping (SPM) is a promising technique to solve this problem.

IEEE Access, 2018 The distribution information of the land-cover classes in remote sensing image can be explored by sub-pixel mapping (SPM) technique. The soft-then-hard sub-pixel mapping (STHSPM) has become an important type of SPM method.

Fast, Sub‐pixel Antialiased Shadow Maps [PDF]
Computer Graphics Forum, 2009 AbstractSolving aliasing artifacts is an essential problem in shadow mapping approaches. Many works have been proposed, however, most of them focused on removing the texel‐level aliasing that results from the limited resolution of shadow maps. Little work has been done to solve the pixel‐level shadow aliasing that is produced by the rasterization on ...

Remote Sensing, 2020 The generation of land cover maps with both fine spatial and temporal resolution would aid the monitoring of change on the Earth’s surface. Spatio-temporal sub-pixel land cover mapping (STSPM) uses a few fine spatial resolution (FR) maps and a time

Joint Sparse Sub-Pixel Mapping Model with Endmember Variability for Remotely Sensed Imagery
Remote Sensing, 2016 Spectral unmixing and sub-pixel mapping have been used to estimate the proportion and spatial distribution of the different land-cover classes in mixed pixels at a sub-pixel scale. In the past decades, several algorithms were proposed in both categories;

Fluvial gravel bar mapping with spectral signal mixture analysis
European Journal of Remote Sensing, 2021 The paper presents a method for mapping fluvial gravel bars based on Sentinel-2 and Landsat imagery. The proposed method therefore uses spectral signal mixture analysis (SSMA) because its results allow the development of land cover fraction maps for ...

Mapping sub‐pixel fluvial grain sizes with hyperspatial imagery [PDF]
Sedimentology, 2013 AbstractThis study presents an investigation of image texture approaches for mapping sub‐pixel fluvial grain‐size features from airborne imagery, allowing for the rapid acquisition of surface sand and coarse fraction (>1·41 mm) grain‐size information.

A New Sub-pixel Map for Image Analysis [PDF]
, 2006 Planar maps have been proposed as a powerful and easy-to-use representation for various kinds of image analysis results, but so far they are restricted to pixel accuracy. This leads to limitations in the representation of complex structures (such as junctions, triangulations, and skeletons) and discards the sub-pixel information available in grayvalue ...

Remote Sensing, 2020 Urban flooding is one of the most costly and destructive natural hazards worldwide. Remote-sensing images with high temporal resolutions have been extensively applied to timely inundation monitoring, assessing and mapping, but are limited by their low ...

Super-resolution reconstruction of seismic section image via multi-scale convolution neural network [PDF]
E3S Web of Conferences, 2021 The resolution of seismic section images can directly affect the subsequent interpretation of seismic data. In order to improve the spatial resolution of low-resolution seismic section images, a super-resolution reconstruction method based on multi-scale
