The widespread adoption of new 3D sensor and authoring technologies has made it possible to capture scenes models in real time with decent visual quality. As an example, Microsoft's Kinect Apple's PrimeSense technology are now being used a wide variety interactive mobile applications, including gaming augmented reality applications. latest smartphones equipped multiple cameras, which can be readily generate depth images. Some the also include depth-ranging sensors that for model generation....
Nowadays, human activity recognition (HAR) plays an important role in wellness-care and context-aware systems. Human activities can be recognized real-time by using sensory data collected from various sensors built smart mobile devices. Recent studies have focused on HAR that is solely based triaxial accelerometers, which the most energy-efficient approach. However, such approaches are still energy-inefficient because accelerometer required to run without stopping so physical of a user...
This paper describes the development of Korean corpus spontaneous speech, also called Seoul corpus. The contains audio recording interview-style speech from 40 native speakers Korean. talkers are divided into four age groups; in their teens, twenties, thirties and forties. Each group has ten talkers, five males females. method used to elicit record is described. containing around 220,000 phrasal words was phonemically labeled along with information on boundaries for utterances, which were...
This article presents a new compression scheme for 3D dynamic meshes, referred to as Video and Subdivision based Mesh Coding (VSMC). The VSMC approach combines displaced subdivision surface model with video-based coding in order achieve efficient performance real-time, low-power decoding playback. In addition, supports rich set of functionalities including scalability (spatial, temporal, quality) progressive transmission. proposed [1] was shown outperform the anchor MPEG Call Proposals on...
The field of digital forensic science emerged as a response to the growth computer crimes. Digital forensics is art discovering and retrieving information about crime in such way make evidence admissible court. Network networked environments. However, amount network traffic huge might crash capture system if left unattended. Not all captured or recorded can be useful for analysis evidence. more traffic, harder analyzing. Therefore, we need an effective automated analyzing forensics. We...
Palette mode is the new coding tool that has been adopted in Screen Content Coding Extensions of High Efficiency Video (HEVC SCC). can represent colour clusters for screen content efficiently and be summarized into two parts: palette tools index map tools. This paper proposes techniques to improve coding: transition copy prediction across unit boundary. The former exploring correlation between an all previously coded indices; latter utilizing along Experimental results reportedly show that,...
In this study, a novel setup for nanoscale finishing process - magnetic abrasive (MAF) was investigated together with in-process monitoring using acoustic emissions (AE). A specially fabricated direction control piece neodymium magnet attached to an MAF perform surface of thin-film (IZO) coated Pyrex glass workpieces within selective area. For the experiments, design experiment (DOE) applied optimize roughness workpieces. addition, emission (AE) sensor, which can effectively monitor and...
To create constantly evolving software, the upgrading is an essential factor. There are two ways to upgrade, pushing and polling. Polling has advantage of keeping latest versions all clients, but can cause heavy server load by simultaneously connections many clients unnecessary network traffics. On other hand, push causes much less because upgrade specific there cumbersome monitoring keep stopped on version. The Half-Push/Half-Polling pattern mixes these different ways, their advantages,...
Palette mode and intra block copy are two new coding tools that have been adopted in the screen content extensions of high efficiency video Ccoding (HEVC SCC). can represent color clusters for efficiently. Intra (IBC) facilitates prediction within same frame. Both demonstrated promising benefits coding. In addition to HEVC SCC, this paper introduces five techniques enhance palette or IBC: transition copy, across unit boundary, advanced motion vector coding, modified temporal merge candidate...
