Computing pseudo-Wigner distribution by the fast Hartley transform
Soo-Chang Pei,Ing-Ing Yang +1 more
TL;DR: The use of the fast Hartley transform (FHT) to evaluate the Wigner distribution entirely in the real domain is proposed, and the computational complexity is reduced from three complex FFTs to three real FHTs.
Compressed Sensing Detector Design for Space Shift Keying in MIMO Systems
Chia-Mu Yu,Sung-Hsien Hsieh,Han-Wen Liang,Chun-Shien Lu,Wei-Ho Chung,Sy-Yen Kuo,Soo-Chang Pei +6 more
TL;DR: This work proposes a compressed sensing based detector, NCS, by formulating the SSK-type detection criterion as a convex optimization problem, which requires only O(ntNrNt) complexity, outperforming the O(NRNtnt) complexity in the ML detector, at the cost of slight fidelity degradation.
Tamper proofing and attack identification of corrupted image by using semi-fragile multiple-watermarking algorithm
Soo-Chang Pei,Yi-Chong Zeng +1 more
- 21 Mar 2006
TL;DR: A novel semi-fragile multiple-watermarking algorithm based on quantization index modulation that achieves the tamper proofing and attack identification of tampered areas and demonstrates that the amount of test images will not influence the accuracy of attack identification.
Image Inpainting For Random Areas Using Dense Context Features
Yu-Zhe Su,Tsung-Jung Liu,Kuan-Hsien Liu,Hsin-Hua Liu,Soo-Chang Pei +4 more
- 01 Sep 2019
TL;DR: Dense blocks for the U-Net architecture are introduced, which can alleviate the problem of gradient disappearance, while also reducing the number of parameters.
Efficient Implementation of Quaternion Fourier Transform, Convolution, and Correlation by 2-D
Soo-Chang Pei,Jian-Jiun Ding,Ja-Han Chang +2 more
- 01 Jan 2001
TL;DR: Efficient algorithms for QFT, QCV, and quaternion correlation are developed and the spectrum-product QCV is developed, which is an improvement of the conventional form of QCV and very useful for quaternions filter design.
