Ultrasonic-based distance measurements using time-of-flight (TOF) is a fundamental technique for different applications across wide variety of fields. In general, cross correlation between transmitted and received signal considered to be the optimal TOF estimation technique, which produces peak at time delay them. Cross provides superior performance in conjunction with linear chirp. However, as its accuracy depends on width peak, inversely proportional signal's bandwidth, it can only said...

The popularity of 3D video is increasing daily due to the availability low-cost televisions and high-speed Internet access. However, currently contents can be distributed illegally without any protection. For views generated using a depth-image-based rendering technique, not only left right as content, but also center, left, or individually 2D content. As digital watermarking possible way protecting these from unauthorized distribution, in this paper, we propose method for rendered video. In...

Cloud removal is an important goal for enhancing the utilization of optical remote sensing satellite images. Clouds dynamically affect signal transmission due to their different shapes, heights, and distribution. In case thick opaque clouds, pixel replacement has been commonly adopted. For thin correction techniques allow effects clouds be removed while retaining remaining information in contaminated pixels. this paper, we develop a new method based on spectral mixture analysis which makes...

Increasing intakes of fruits and vegetables intake, in tandem with reducing consumption energy-dense nutrient poor foods beverages are dietary priorities to prevent chronic disease. Although most adults do not eat enough fruit vegetables, teenagers young tend have the lowest intakes. Young typically consume a diet which is inconsistent recommendations. Yet little known about best approaches improve behaviours among this group. This randomised controlled trial aims evaluate effectiveness...

Light field (LF) technology has been popularly adopted by a wide range of conventional industries. However, one problem when dealing with LFs is the sheer size data volume. There have many multi-view video coding (MVC)-based LF methods reported in literature, aiming at finding best prediction structure for coding. It clear that number possible structures unlimited, and it also observed bit-rate can be reduced increasing bi-directionally encoded views structure. none work conducted to analyze...
