Closed-Form Orthogonal Ramanujan Integer Basis
Soo-Chang Pei,Kuo-Wei Chang +1 more
TL;DR: In this letter, a closed-form orthogonal Ramanujan integer basis is proposed and obtained by performing Gram-Schmidt process from theRamanujan sum and its circular shift, which has a surprisingly simple and sparse form, which is better than the original complete Ramanuj basis.

Recursive order-statistic soft morphological filters
Soo-Chang Pei,Chin-Lun Lai,Frank Y. Shih +2 more
- 01 Jan 1998
TL;DR: In this article, a recursive order-statistic soft morphological (ROSSM) filters are proposed and their important properties related to morphological filtering are developed, and criteria for specific selection of parameters are provided to achieve excellent performance in noise reduction and edge preservation.

Design of complex FIR filters with arbitrary complex frequency responses by two real Chebyshev approximations
Soo-Chang Pei,Jong-Jy Shyu +1 more
TL;DR: In this article, the problem of designing complex FIR filters is solved by dividing the original complex approximation into two real ones such that the Remez exchange algorithm can be applied by slightly modifying the Parks-McClellan-McCalling program.
Power-scalable multi-layer halftone video display for electronic paper
Chao-Yung Hsu,Chun-Shien Lu,Soo-Chang Pei +2 more
- 26 Aug 2008
TL;DR: This paper proposes a power-scalable multi-layer halftone video display scheme, which is composed of layer coding, non-uniform sampling, and flicker rate reduction, and demonstrates the effectiveness of the proposed method.
Split-vector radix 2-D fast Fourier transform
Soo-Chang Pei,Ja-Lin Wu +1 more
TL;DR: In this article, the split vector radix was used to develop a 2D fast Fourier transform (FFT) algorithm; it was performed "in-place", and required no matrix transpose operation.
