In this work, an inter-layer residual prediction method that has low complexity and minimal syntax changes is proposed to improve the rate-distortion RD performance of scalable video coding. The proposed method employs a new inter-layer reference picture that is compensated for by a residual signal from the corresponding base layer. The compensated(More)
Rate control is an important component of an end-to-end video communication system. Currently, there are several proposals for rate control in the upcoming High Efficiency Video Coding (HEVC) standard, but none specifically for the multi-view extension of the standard. In this paper, we apply one of the HEVC single-view rate control schemes to the(More)
This paper proposes an approach based on an optical imaging technique for the period measurement of fiber Bragg gratings (FBG). The simple, direct technique involves a differential interface contrast (DIC) microscope and a high-resolution CCD camera. Image processing is performed on the microscope images to obtain low-noise grating profiles and then the(More)
This study examined the etch characteristics of ZrO2 etched using an atomic layer etching (ALET) system with BCl3 gas for adsorption and an Ar neutral beam for desorption. The effect of the BCl3 gas pressure and Ar neutral beam dose on the etch characteristics was examined. The results showed that the ZrO2 etch rate was maintained at a constant etch rate of(More)
The effect of the fluorination of aluminum oxide (Al2O3) in an oxide-nitride-aluminum oxide (SiO2-Si3N4-Al2O3, ONA) layer through fluorine (F) ion and neutral-beam treatments on the characteristics of the ONA layer was investigated to study the effect of charge-related damage during F ion beam treatment. The treatment with an F beam at approximately 10 eV(More)
—In this paper, we propose a video compression algorithm based on human visual perception for High Efficiency Video Coding (HEVC). The proposed algorithm is applied to the conventional lossy coding to reduce bitrate without any further subjective quality degradation. It improves coding performance by allowing objective quantization error which is not(More)
