However, the raw point clouds acquired suffer inevitably from noise, which challenges their applications in 3D computer vision. In order to address this problem, we propose a novel feature-preserving filtering framework, termed Guided Normal Point Cloud Filter. First, we perform initial normal ...
However, low-pass filtering on Fourier analysis can- not effectively distinguish the high-frequency part of the re- quired signal from the high-frequency interference caused by noise. Wavelet can well retain the peak value and muta- tion part of th...
the related DBs are filtered and drilled down to identify those DBs1and2that are correlated to the specific business transaction. The process of filtering and drilling down is repeated until the root cause is found. For example, in the third row of FIG. 9, the machine entities are filtered...
Techniques for planar region-guided estimates of 3D geometry of objects depicted in a single 2D image. The techniques estimate regions of an image that are part of planar regions (i.e., flat surfaces) and use those planar region estimates to estimate the 3D geometry of the objects in the ...
b) filtering attributes that are highly correlated with each other. c) transposing the input to less features (perform PCA Analysis) d) discretizing features The resulting symptoms need to be balanced so as to come up with unbiased results. For example, in order for the algorithm to be able...
(OL43) according to the same count filtering steps as described above. We generated per-genome-base activity measurements by averaging the MPRA activity of each oligo that overlaps that base pair. We removed oligo genomic coordinates that overlap with those in the UKBB and GTEx libraries in ...
Furthermore, we design a corresponding point matching module, which includes a two-stage point filtering strategy. This method effectively improves the ability to identify embedded inliers from outliers and accurately remove spurious matches, thus allowing the network to focus more on the accurate ...

Nearest-neighbor feature pairs are created between the point clouds by using k-dimensional trees. These are used in combination with the TEASER + + robust outlier filtering algorithm to achieve global registration [45,46,47] TEASER + + is a rigid body registration algorithm...
unsharp masking; edge-aware weighting; guided filtering; 3D acoustic point cloud; water-conveyance tunnel1. Introduction Water-conveyance tunnels are the main structures of water-diversion projects. When water-diversion projects enter the operational period, special attention must be paid to the health...
