Based on the observation that low-frequency DCT coefficients of an image are less affected by geometric processings, we propose a new blind MPEG-2 video watermarking algorithm robust to camcorder recording. The mean of the low-frequency DCT coefficients of the video is temporally modulated according to the information bits. To avoid watermark’s drift into(More)
This paper presents a blind digital video watermarking scheme, which is especially robust to camcorder recording attacks and also to a variety of common video processing and geometric distortions. Using the fact that nearby frames of a video sequence are quite similar, the method embeds the watermark by temporal modulation of the frames. The watermark(More)
OBJECTIVE It has been suggested that insulin resistance, low-grade inflammation and vitamin D deficiency are associated with obesity and sarcopenia. However, their relationships with sarcopenic obesity (SO) are unclear. We evaluated the impact of homoeostasis model assessment of insulin resistance (HOMA-IR), high-sensitivity C-reactive protein (hsCRP) and(More)
BACKGROUND AND OBJECTIVES The volume of the air cavities in the paranasal sinuses is not only the simplest, but also the most important index for paranasal sinus evaluation. However, few volumetric studies have been performed in all age groups. The purpose of the current study was to outline the normal development of paranasal sinuses in all age groups, and(More)
Molecular lesions in Wnt/beta-catenin signaling and subsequent up-regulation of beta-catenin response transcription (CRT) occur frequently during the development of colon cancer. To identify small molecules that suppress CRT, we screened natural compounds in a cell-based assay for detection of TOPFalsh reporter activity. Murrayafoline A, a carbazole(More)
OBJECTIVE The aim of this study was to evaluate effect of pulsed radiofrequency (PRF) neuromodulation of suprascpaular nerve (SSN) in patients with chronic shoulder pain due to adhesive capsulitis and/or rotator cuff tear. METHODS The study included 11 patients suffering from chronic shoulder pain for at least 6 months who were diagnosed with adhesive(More)
