In this paper, we propose a new spatio-temporal representation for gait recognition. Firstly, the new representation of gait is constructed, which is the average of the Hough transformed images in one complete cycle of a silhouette sequence. Secondly, we project the new representation to low dimension by applying Principal Component Analysis. Finally, the(More)
In this paper, we propose a novel approach for palmprint recognition, which combine band-limited phase-only correlation method and directional representation of palmprint. We also exploit peak-to-sidelobe ratio as the similarity measure. The results of experiments conducted on Hong Kong Polytechnic University Palmprint Database show that the proposed(More)
In this paper, we propose a novel palmprint retrieval scheme based on principal lines. In the proposed scheme, the principal lines are firstly extracted by the modified finite radon transform. And then, a lot of key points located in three principal lines i.e. heart line, life line and head line are detected. Finally, the palmprints are retrieved by several(More)
In ubiquitous multimedia applications, how to protect the digital copyright for multimedia data has been a difficult task. In this paper, a novel self-adaptive video dual watermarking, which is combined the motion characteristics detection with the geometric invariant of Scale-invariant feature transform (SIFT) is proposed. For each frame, the motion(More)
OBJECTIVE To study the availability and method of the dorsal approach to arthroscopic lateral release in hallux valgus (HAV) surgery. METHODS Ten fresh foot specimens with ankle preserved were included. Lateral capsule and the oblique head of hallucis adductus muscle were released using blade under arthroscopic visualization. Inspection was made for the(More)
OBJECTIVE To investigate the method and result of arthroscopic trans-septal approach (ATS). METHODS Ten fresh cadaveric knees were prepared for anatomical study about the posterior septum, and 65 posterior compartment arthroscopy of the knees were performed to view the structure of the posterior septum. The initial diagnosis included: rheumatoid(More)
To solve the problem with low Due Date Performance (DDP) and throughput in clothing enterprises, we propose a new bottleneck scheduling algorithm, design and implement production planning system with a core of the algorithm based on Drum-Buffer-Rope (DBR) theory. Firstly, Shipping Buffer model is built for typical clothing enterprises; secondly, some(More)
To enable rational multi-epitope vaccine and diagnostic antigen design, it is imperative to delineate complete IgG-epitome of the protein. Here, we describe results of IgG-epitome decoding of three proteins from high-risk (HR-) oncogenic human papillomavirus type 58 (HPV58). To reveal their entire epitomes, employing peptide biosynthetic approach, 30(More)
