Effects of depolarizing quantum channels on BB84 and SARG04 quantum cryptography protocols
We report experimental studies on the effect of the depolarizing quantum
channel on weak-pulse BB84 and SARG04 quantum cryptography. The experimental
results show that, in real world conditions in which channel depolarization
cannot be ignored, BB84 should perform better than SARG04.Comment: 4 pages, 4 figure
Recursive Video Lane Detection
A novel algorithm to detect road lanes in videos, called recursive video lane
detector (RVLD), is proposed in this paper, which propagates the state of a
current frame recursively to the next frame. RVLD consists of an intra-frame
lane detector (ILD) and a predictive lane detector (PLD). First, we design ILD
to localize lanes in a still frame. Second, we develop PLD to exploit the
information of the previous frame for lane detection in a current frame. To
this end, we estimate a motion field and warp the previous output to the
current frame. Using the warped information, we refine the feature map of the
current frame to detect lanes more reliably. Experimental results show that
RVLD outperforms existing detectors on video lane datasets. Our codes are
available at https://github.com/dongkwonjin/RVLD.Comment: ICCV 2023 accepte
BiFormer: Learning Bilateral Motion Estimation via Bilateral Transformer for 4K Video Frame Interpolation
A novel 4K video frame interpolator based on bilateral transformer (BiFormer)
is proposed in this paper, which performs three steps: global motion
estimation, local motion refinement, and frame synthesis. First, in global
motion estimation, we predict symmetric bilateral motion fields at a coarse
scale. To this end, we propose BiFormer, the first transformer-based bilateral
motion estimator. Second, we refine the global motion fields efficiently using
blockwise bilateral cost volumes (BBCVs). Third, we warp the input frames using
the refined motion fields and blend them to synthesize an intermediate frame.
Extensive experiments demonstrate that the proposed BiFormer algorithm achieves
excellent interpolation performance on 4K datasets. The source codes are
available at https://github.com/JunHeum/BiFormer.Comment: Accepted to CVPR202
P-union and P-intersection of neutrosophic cubic sets
Conditions for the P-intersection and P-intersection of falsity-external (resp. indeterminacy-external and truth-external) neutrosophic cubic sets to be an falsity-external (resp. indeterminacy-external and truthexternal) neutrosophic cubic set are provided. Conditions for the Punion and the P-intersection of two truth-external (resp. indeterminacyexternal and falsity-external) neutrosophic cubic sets to be a truthinternal (resp. indeterminacy-internal and falsity-internal) neutrosophic cubic set are discussed
Serially Connected Micro Amorphous Silicon Solar Cells for Compact High-Voltage Sources
We demonstrate a compact amorphous silicon (a-Si) solar module to be used as high-voltage power supply. In comparison with the organic solar module, the main advantages of the a-Si solar module are its compatibility with photolithography techniques and relatively high power conversion efficiency. The open circuit voltage of a-Si solar cells can be easily controlled by serially interconnecting a-Si solar cells. Moreover, the a-Si solar module can be easily patterned by photolithography in any desired shapes with high areal densities. Using the photolithographic technique, we fabricate a compact a-Si solar module with noticeable photovoltaic characteristics as compared with the reported values for high-voltage power supplies
