Nearly five million individuals in the US have limited arm and hand movement, making it difficult or impossible for them to use computers products with embedded computers, such as wheelchairs, household appliances, office electronic equipment, robotic aids. Although some current wheelchair systems they very little computer control require precise, low-level inputs from user; interfaces are similar those found passenger cars. The rider must continuously specify chair's direction and, cases,...

There are many subjective assessment methods, depending on the purpose of video quality evaluation, provided by ITU-T and ITU-R recommendations. We compared eight Double-Stimulus Continuous Quality-Scale (DSCQS), Impairment Scale (DSIS), ACR 5-grade scale (ACR5), ACR5 with Hidden Reference (ACR5-HR), 11-grade (ACR11), ACR11-HR, Subjective Assessment Multimedia Video Quality (SAMVIQ), SAMVIQ-HR, to clarify their applicability a variety assessment. To do this, we evaluated total time...

This paper presents the relationship between Hurst Exponent (H) and Rescaled Range Analysis (R/S) in classification of Foreign Exchange Market (FOREX) time series by supposition existence a Fractal an alternative to traditional theory Capital Markets.In such way, is metric capable providing information on correlation persistence series.Many systems can be described self-similar fractals as Fractional Brownian Motion, which are well characterized this statistic.

In this paper we present a general methodology for designing mirrors of catadioptric onmidirectional sensors encompassing linear projection properties, the so called constant resolution cameras. The linearity is stated between 3D distances (or angles) and pixel coordinates. We include three practical cases interest constraints both standard (cartesian distribution) log-polar cameras: vertical, horizontal angular resolution. Finally, formulation applied in camera combining some presented...

We propose a no reference video-quality-assessment model for estimating the quality of experience (QoE) video streaming services using features derived from decoded signals. The proposed is useful as QoE monitoring tool services. It takes into account impact compression on by blockiness and blur conducted subjective assessments validated performance model. Test results show that estimates with high quality-estimation accuracy.

Assembly processes for simple toys or complex machines require instructions to be executed. Traditionally, these are written in the form of paper digital manuals. These manuals contain descriptive text, photos diagrams guide assembly sequence from beginning final state. To change this paradigm, an augmented reality system is proposed users tasks. The recognizes each piece assembled through image processing techniques and guides placement with graphic signs. Still, checks if pieces properly...

This need leads argue about alternatives prediction time series using machine learning methods. paper aims describe development SVR-wavelet model, an adaptive hybrid which integrates wavelet models Support Vector Regression (SVR), for series, particularly applied Foreign Exchange Market (FOREX), obtained from public...

A professional-image-quality video encoder LSI for broadcasting and content distribution has been developed with single-chip 4K 60-fps 4:2:2 high-efficiency coding (HEVC) encoding capability 8K ultrahigh definition television scalability. Edge-based intramode pruning statistically adaptive multiblock-size motion estimation (ME) efficiently reduce HEVC's high computational complexity real-time processing, while a deeply centralized-mode decision framework maintains compression performance....

This paper proposes the world's first single-chip 4K 60fps 4:2:2 HEVC video encoder LSI (named "NARA") with 8K scalability for broadcasting professional high image quality. It consists of a prediction core new mode decision framework, dual coding cores, controlling RISCs, and speed data buses multichip configuration, using 28nm CMOS technology. The NARA will lead to dimension in future high-quality world.

Object Robotic surgery can be applied as a novel technology. Our master-slave microscopic-micromanipulator system (NeuRobot), which has rigid endoscope and three robot-arms, been developed to perform neurosurgical procedures, employed successfully in some clinical cases. Although the master slave parts of NeuRobot are directly connected by wire, it is possible separate each part apply telesurgery with modifications. To evaluate feasibility telesurgery, basic experiments were performed....

Omnidirectional vision systems can provide images with a 360° of field view. For this reason, they be useful to robotic applications such as navigation, teleoperation and visual servoing. An effective way construct type system is by combining lenses mirrors together resulting on that does not require the movement camera direction attention robot. A typical construction mounting convex mirror in front aligning center optical axis camera. The most common shapes used are conic, parabolic,...

With the development of broadband IP networks, video distribution, streaming, and communication services over networks are rapidly becoming common. To provide these appropriately, we must design, monitor, manage their quality based on subjective quality. Therefore, need an objective assessment method that enables to be evaluated from characteristics easily quickly. We have already proposed for freeze distortion in network by considering perceptual short distortion. In this previous method,...

[Purpose] We aimed to analyze parameters of pulmonary function and physiological, psychological, physical factors in patients with chronic obstructive disease (COPD) receiving rehabilitation (PR) music therapy (MT). [Participants Methods] This randomized crossover comparative study included in-patients diagnosed COPD a ratio forced expiratory volume measured at the first second vital capacity (FEV1/FVC) <70% after administration bronchodilator. Patients were randomly divided into two groups...

IPTV services are attracting attention as an influential application of the next-generation network (NGN). Managing in-service communication quality based on users' experience (QoE) is very important for improving customer satisfaction. For this, accurate and efficient quality- assessment technology desired. This called objective has been studied a long time. However, there hardly any studies methods that can be applied to monitoring at user's premise. In this paper, we first overview...

Stereoscopic high definition video is one of the promising next-generation services because 3D can express more life-like visual experiences. quality experience affected by employed codec and format. Therefore, we conducted extensive subjective assessments for side-by-side frame-sequential sequences using different codecs.
