This paper proposes a wavelet-tree-based blind watermarking scheme for copyright protection. The wavelet coefficients of the host image are grouped into so-called super trees. The watermark is embedded by quantizing super trees. The trees are so quantized that they exhibit a large enough statistical difference, which will later be used for watermark(More)
—In this paper, we proposed a platform based bus-interleaved architecture for the deblocking filter in H.264/MPEG-4 AVC. Specifically, to efficiently use the bus bandwidth, we classify the filtering mode into 8 types and use an adaptive transmission scheme to avoid redundant data transfers. Moreover, to reduce the processing latency, we use a(More)
We present a baseline MPEG-4 AVC (Advanced Video Coding) decoder based on an optimized platform-based design methodology. With this methodology, we jointly optimize the software and hardware design of the decoder. Overall decoding throughput is increased by synchronizing the software and the dedicated co-processors. The synchronization is achieved at(More)
We present a baseline MPEG-4 Advanced Video Coding (AVC) decoder based on the methodology of joint optimization of software and hardware. The software is first optimized with algorithm improvements for frame buffer management, boundary padding, content-aware inverse transform and context-based entropy decoding. The overall decoding throughput is further(More)
PURPOSE We aimed to investigate the association of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) with cardiometabolic risk. METHODS In this cross-sectional study, 21,038 men and 15,604 women who participated in a health check-up were included. RESULTS In both men and women, the area under the curve (AUC) of WHtR was(More)
In this paper, we present an ARM platform-based architecture design for de-blocking filter in H.264. According to statistical analysis, we propose an adaptive transmission scheme to reduce the bus workload. Moreover, we develop a bus-interleaved architecture to reduce the processing latency. As compared to the state-of-the-art designs, our scheme offers 3x(More)
BACKGROUND Serum C-reactive protein (CRP) and leptin levels have been independently associated with the cardiovascular risk factors. The aim of the present study was to determine if their serum levels were associated with cardiovascular risk factors or metabolic syndrome as well as their correlation in the Taiwanese population. METHODS This retrospective(More)
BACKGROUND Leptin is associated with cardiovascular disease (CVD); however, few studies have assessed its relationship with metabolic syndrome, especially in an Asian population. Therefore, the aim of the present study was to assess leptin levels and evaluate its association with CVD and metabolic syndrome. METHODS In 2009, 957 subjects, who underwent a(More)
