A Fast Two-Stage Bilateral Filter Using Constant Time O(1) Histogram Generation [PDF]
Sensors, 2022 Bilateral Filtering (BF) is an effective edge-preserving smoothing technique in image processing. However, an inherent problem of BF for image denoising is that it is challenging to differentiate image noise and details with the range kernel, thus often ...

CTIDH: faster constant-time CSIDH
Transactions on Cryptographic Hardware and Embedded Systems, 2021 This paper introduces a new key space for CSIDH and a new algorithm for constant-time evaluation of the CSIDH group action. The key space is not useful with previous algorithms, and the algorithm is not useful with previous key spaces, but combining the ...

Median Filtering in Constant Time [PDF]
IEEE Transactions on Image Processing, 2007 The median filter is one of the basic building blocks in many image processing situations. However, its use has long been hampered by its algorithmic complexity of O (r) in the kernel radius. With the trend toward larger images and proportionally larger filter kernels, the need for a more efficient median filtering algorithm becomes pressing.

Determination of the time constant of measuring transducers
Measurement: Sensors, 2021 The methods for the experimental determination of the time constant of measuring transducers are described. The method is based on determining the parameters of the steady-state response of the measuring transducer using a periodic sequence of ...

Andromeda’s Parachute: Time Delays and Hubble Constant
The Astrophysical Journal, 2023 The gravitational lens system PS J0147+4630 (Andromeda’s Parachute) consists of four quasar images ABCD and a lensing galaxy. We obtained r -band light curves of ABCD in the 2017−2022 period from monitoring with two 2 m class telescopes.

Point Location in Constant Time
CoRR, 2023 We preprocess the input subdivision with $n$ points on the plane in $O(n\sqrt{\log n})$ time to facilitate point location in constant time. Previously the preprocessing time is $O(n\log n)$ and point location takes $O(\log n)$ time.

MSSA: Constant Time State Search through Multi-Scope State Area
Applied Sciences, 2022 In the stateful data plane, the switch can record the state and forward packets based on the local state. This approach makes it possible to integrate complex network applications into the data plane, thus reducing the amount of communication required ...

Software Toolkit for HFE-based Multivariate Schemes
Transactions on Cryptographic Hardware and Embedded Systems, 2019 In 2017, NIST shook the cryptographic world by starting a process for standardizing post-quantum cryptography. Sixty-four submissions have been considered for the first round of the on-going NIST Post-Quantum Cryptography (PQC) process.

Why the Kemeny Time is a constant
Special Matrices, 2016 We present a new fundamental intuition forwhy the Kemeny feature of a Markov chain is a constant. This new perspective has interesting further implications.
