BEIJING, Jan. 8 (Xinhua) -- Chinese experts have published a single cell spatio-temporal map of human limb development, shedding light on the cell evolution path and the determination process of cell spatial position in fetal limbs. Human limbs emerge during the fourth post-conception week as ...
Spatial-temporal fraction map fusion with multi-scale remotely sensed images. Remote Sens Environ, 2018, 213: 162–181 Fit-FC使用三种模型,即回归拟合、空间滤波和残差补偿来进行Sentinel-2和Sentinel-3图像之间的STF[45]。 [45] Wang Q, Atkinson P M. Spatio-temporal fusion for daily Sentinel-2 ...
介绍一下关于action recognition的结果:在Charader数据集上,通过用scene-graph features替换LFB(long-term feature bank)的feature banks ,能在SOTA的LFB上提升1.8% mAP。 另外还做了一个验证实验,假设真实的scene graph是存在的情况下,也就是直接用手工标注的GT进行scene-graph的构建,能在mAP上获得16%的提升。 五...
The application of the hierarchical Voronoi data structure presented in this research is in spatio-temporal map generalization, which is needed for reasoning about dynamic aspects of the world, primarily about actions, events and processes. This provides an advance in the domain of map generalization...
In this paper, we present a formalism for representing spatio-temporal changes and a method for map updates, based on the topological properties of the line Voronoi diagram. This new approach can overcome some of the problems with existing spatio-temporal models. We preserve the spatio-temporal ...
We employ Netatmo crowd-sourced weather station data and three geospatial mapping approaches: (1) Ordinary Kriging, (2) statistical ML model (using predictors primarily derived from Earth Observation Data), and (3) weather research and forecasting model (WRF) to predict/map daily Ta at nearly 1...
Location map of Ramsar wetland sites in mainland China. The table represents names of the wetlands (NNR: National Nature Reserve and NR: Nature Reserve). This figure is created using QGIS 3.30.1 (Quantum Geographic Information System; https://download.qgis.org/downloads/) and the background ...
BSD-3-Clause license Khronos Khronos is a unified approach that can reason about short-term dynamics and long-term changes when performing online metric-semantic simultaneous mapping and localization (SLAM) in dynamic environments. A few instances from Khronos’ spatio-temporal map, representing the ...
