A Fast Algorithm for Intra-Frame Versatile Video Coding Based on Edge Features [PDF]
Sensors, 2023 Versatile Video Coding (VVC) introduces many new coding technologies, such as quadtree with nested multi-type tree (QTMT), which greatly improves the efficiency of VVC coding. However, its computational complexity is higher, which affects the application

A Super Fast Algorithm for Estimating Sample Entropy [PDF]
Entropy, 2022 Sample entropy, an approximation of the Kolmogorov entropy, was proposed to characterize complexity of a time series, which is essentially defined as −log(B/A), where B denotes the number of matched template pairs with length m and A denotes the number ...

A Fast Algorithm for 2D DOA Estimation Using an Omnidirectional Sensor Array [PDF]
Sensors, 2017 The traditional 2D MUSIC algorithm fixes the azimuth or the elevation, and searches for the other without considering the directions of sources. A spectrum peak diffusion effect phenomenon is observed and may be utilized to detect the approximate ...

Wavelet p-analogs of the discrete Haar transform [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021 Two $p$-analogs (for $p>2$) of the discrete version of the Haar system in vector symbolism are proposed and fast algorithms are constructed based on them.

Fast 3D-HEVC Depth Intra Coding Based on Boundary Continuity
IEEE Access, 2021 The encoding format of the 3D extension of high efficiency video coding (3D-HEVC) consists of a multiview color texture and an associated depth map. Because of the unique characteristics of the depth map, advanced coding techniques are designed for depth

Fast Control for Backlight Power-Saving Algorithm Using Motion Vectors from the Decoded Video Stream
Sensors, 2022 Backlight power-saving algorithms can reduce the power consumption of the display by adjusting the frame pixels with optimal clipping points under some tradeoff criteria. However, the computation for the selected clipping points can be complex.

Ising Model for Interpolation of Spatial Data on Regular Grids
Entropy, 2021 We apply the Ising model with nearest-neighbor correlations (INNC) in the problem of interpolation of spatially correlated data on regular grids. The correlations are captured by short-range interactions between “Ising spins”.
