Configurable pixelated skyrmions on nanoscale magnetic grids
Xichao Zhang, Jing Xia, Keiichiro Shirai +5
Topological spin textures can serve as non-volatile information carriers. Here we study the current-induced dynamics of an isolated magnetic skyrmion on a nanoscale square-grid pin…
Guided Facial Skin Color Correction
Keiichiro Shirai, Tatsuya Baba, Shunsuke Ono +3
This paper proposes an automatic image correction method for portrait photographs, which promotes consistency of facial skin color by suppressing skin color changes due to backgrou…
Fast Singular Value Shrinkage with Chebyshev Polynomial Approximation Based on Signal Sparsity
Masaki Onuki, Shunsuke Ono, Keiichiro Shirai +1
We propose an approximation method for thresholding of singular values using Chebyshev polynomial approximation (CPA). Many signal processing problems require iterative application…
Fast Supervised Discrete Hashing and its Analysis
Gou Koutaki, Keiichiro Shirai, Mitsuru Ambai
In this paper, we propose a learning-based supervised discrete hashing method. Binary hashing is widely used for large-scale image retrieval as well as video and document searches…
