CIA-SSD这篇文章以SECOND为Backbone提出了一种基于体素的一阶段目标检测模型,其基本思想是校准单步目标检测中分类和定位两个任务,提出Confident IoU-Aware Single-Stage object Detector (CIA-SSD)。 第一个是Spatial-Semantic Feature Ag...
Voxel Farm allows you to get in control of spatial data like never before Large Sites Cover millions of square kilometers at high resolution. Whether it is about the real world or a virtual world, Voxel Farm can store it. Increasing Detail Keep spatial information at the sub-micrometer scale...
In this paper,firstly we have analyzed the processing methods based on pixels of moderate spatial resolution remote sensing(MSRRS) data,including the classification methods based on statistics theory and the classification methods based on nonparametric theory. 首先分析了基于像素的中分辨率卫星数据的遥感...

Voxelmaps mission is to build a true 3D volumetric model of the planet, combining visual, spatial and temporal data to create the most detailed map of the world.
For the spatial distribution of pointqi, the surface distribution of the point cloud is similar to a Gaussian distribution under a dense surface resolution. For Gaussian functionG(||{\mathbf{pq}}_{{\mathbf{i}}} ||) = \frac{1}{{\sqrt {2\pi \sigma^{2} } }}e^{{ - \frac{{(||...
The nominal spatial resolution of the functional data was 1.5 mm × 1.5 mm × 1.5 mm. Data preprocessing Functional volumes from each run were motion-corrected using the FSL MCFLIRT routine. A brain-mask was extracted from the first run of the first session using the FSL BET routine. All ...
Spatial correlation of sub-volume fractions The Sørensen-Dice coefficient, quantifying similarity of the sub-volume fractions, was 0.72 between volumes with TTP < 20 min p.i. and with negative Slope15–40, indicating a high overlap of both properties. The Sørensen-Dice coefficients of sub...
Naturally, it is desirable to obtain a sharp image with good spatial resolution. Therefore, the voxel size should be as small as practically possible. The smaller the voxel's volume, the more voxels one would have in the reconstructed image, the more representative thecvalue of the voxel's ...
