Terahertz Image Restoration Benchmarking Dataset

Yixiong Zhang, Zhipeng Su, Feng Qi, Jianyang Zhou, Xiao-Ping Zhang

ICASSP 2022accepted

The paper introduces a new terahertz (THz) image benchmarking dataset for THz imaging. The degradation of THz image quality is one of the main problems caused by system noise, intrinsic long-wavelength, and diffraction phenomena. In this paper, the point spread function of the THz imaging process is…

Parameter estimation of polynomial phase signal based on low-complexity LSU-EKF algorithm in entire identifiable region

Zhen-miao Deng, Rongrong Xu, Yixiong Zhang, Ping-ping Pan, Ru-jia Hong

ICASSP 2016accepted

Fast implementation of parameter estimation for polynomial phase signal (PPS) is considered in this paper. A method which combines the least squares unwrapping (LSU) estimator and the extended Kalman filter (EKF) is proposed. A small number of initial samples are used to estimate the PPS's parameter…
