This paper presents an overview of deinterlacing techniques and describes some advanced motion compensated de-interlacing techniques in more detail. These motion compensated methods are analyzed and mutually compared. It is concluded that the success of motion compensated de-interlacing depends critically on a protection mechanism. A good example is presented.

Chronic hepatitis B virus (CHB) infection is a burden on global healthcare and is associated with a higher risk of serious sequelae, including cirrhosis and hepatocellular carcinoma. The clinical application of entecavir as a treatment for CHB has produced positive outcomes, and so is an attractive form of pharmacological therapy. However, little data exists comparing the safety and efficacy of...

By introducing rotation compensation into a human iris matching system, improved matching is demonstrated while reducing both the computational complexity and storage requirements. This is achieved by using Fourier domain cross correlation to estimate the relative rotation of two iris images. This eliminates the need to store and compare codes from multiple orientations of the same image. Inste...

A fundamental problem in differential geometry is to characterize intrinsic metrics on a two-dimensional Riemannian manifold M2 which can be realized as isometric immersions into R3. This problem can be formulated as initial and/or boundary value problems for a system of nonlinear partial differential equations of mixed elliptic-hyperbolic type whose mathematical theory is largely incomplete. I...

BACKGROUNDS Serum hepatitis B surface antigen (HBsAg) levels are associated with fibrosis in patients with chronic hepatitis B (CHB) infection. OBJECTIVES The aim of our study was to evaluate serum HBsAg level as a biomarker for compensated cirrhosis in hepatitis B e antigen (HBeAg) positive CHB patients. PATIENTS AND METHODS Two-hundred and one HBeAg-positive Chinese CHB patients with or w...

Aim To optimize conventional coronary optical coherence tomography (OCT) images using the attenuation-compensated technique to improve identification of plaques and the external elastic lamina (EEL) contour. Methods and Results The attenuation-compensated technique was optimized via manipulating contrast exponent C, and compression exponent N, to achieve an optimal contrast and signal-to-nois...

Deliberate dopant compensation has proven to be an effective way to control ingot resistivity, although the impact of compensation on carrier recombination and mobilities remains under investigation. This paper summarizes recent findings regarding the carrier transport properties of compensated silicon. The capacity of common mobility models to describe compensated silicon is reviewed and compa...

Cybersickness is often experienced when viewing virtual environments through head-mounted displays (HMDs). This study examined whether vection (i.e., illusory self-motion) and mismatches between perceived and physical head motions contribute to such adverse experiences. Observers made oscillatory yaw head rotations while viewing stereoscopic optic flow through an Oculus Rift HMD. Vection and cy...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...
