This paper investigates facial expression effects in face recognition from 3D shape using partial ICP. The partial ICP method could implicitly and dynamically extract the rigid parts of facial surface by selecting a part of nearest points pairs to calculate dissimilarity measure during registration of facial surfaces. The method is expected to be able to(More)
—In this paper, a zero-phase odd-harmonic repetitive control scheme is proposed for pulse-width modulation inverters. The proposed repetitive controller combines an odd-harmonic periodic generator with a noncasual zero-phase compensation filter. It occupies less data memory than a conventional repetitive controller does. Moreover, it offers faster(More)
Manganese superoxide dismutase (MnSOD) is a latent tumor suppressor gene. To investigate the therapeutic effect of MnSOD and its mechanisms, a replication-competent recombinant adenovirus with E1B 55-kDa gene deletion (ZD55) was constructed, and human MnSOD and tumor necrosis factor– related apoptosis-inducing ligand (TRAIL) genes were inserted to form(More)
In this paper, we propose an algorithm to track welding line of TiG welding in welding pipe or tube. The proposed algorithm consists of detecting edge, binarization, segmenting target area, locating welding torch and locating welding line. Firstly, we use prewitt operator to form the edge of image which is acquired from industrial camera. Secondly, we(More)
In repetitive control system, the period of exogenous signals must be the integer number of sampling points. However, it can not be always satisfied in real applications. In this paper, a systematic approach for non-integer delay repetitive control system with fixed sampling rate is proposed. The proposed fractional delay based repetitive control scheme(More)
