Exponential growth in multimedia streaming traffic over the Internet motivates the research and further investigation of the user's perceived quality of such services. Enhancement of experienced quality by the users becomes more substantial when service ...

Adaptive bitrate (ABR) algorithms play a crucial role in delivering the highest possible viewer's Quality of Experience (QoE) in HTTP Adaptive Streaming (HAS). Online video streaming service providers use HAS - the dominant video streaming technique on ...

Accessibility, which includes usability evaluation, is an important equity step in assessing the effectiveness and usefulness of online learning for students with sensory disabilities. A model for accessibility evaluation has been developed on the basis ...

Formulation of perceptual objective metrics for haptic interaction evaluation is still a challenge. These metrics are created including the human perception and the distortion intensity of the haptic signals, however, they disregarded peculiarities of ...

Informatics on education is modifying the school environment by making usage of digital resources, which need to be suitable so they do not disturb the learning process. For such, evaluative approaches are applied before educational softwares (ES) are ...

Packet loss may lead to serious degradation of video quality in network communication. Sometimes a router must drop quite a lot of packets to alleviate the congestion. This paper designs multiple dropping schemes for H.264 videos, considering varying ...

In this paper, an objective way to evaluate artistic voice of singing is discussed. The authors take F1 (the first Formant), F3 (the third Formant), fundamental frequency, vocal range, perturbation of F1, perturbation of F3 and average energy as the ...

This paper introduces the method of analyzing the requirements of input signal error from vehicle stability control algorithm. This method is in Carsim & Matlab/Simulink joint simulation platform, by drawing the simulated vehicle track under double lane ...

We aim to predict the perceived quality of estimated source signals in the context of audio source separation. Recently, we proposed a set of metrics called PEASS that consist of three computation steps: decomposition of the estimation error into three ...

Although a large number of background subtraction (BS) algorithms have been proposed, relevant objective metrics for evaluating these algorithms are still lacking. In this paper, empirical discrepancy metrics, which quantify the spatial accuracy and ...

Many kinds of distortion take place during the digital image acquisition, processing, compression, storage, transmission and copy. All of these distortions would lead to a decline in visual quality of the image. Therefore, the image quality assessment ...

Recent advances in 3-D graphics technologies have led to an increasing use of processing techniques on 3-D meshes, such as filtering, compression, watermarking, simplification, deformation, and so forth. Since these processes may modify the visual ...

This paper examines the performance of several source separation systems on a speech separation task for which human intelligibility has previously been measured. For anechoic mixtures, automatic speech recognition (ASR) performance on the separated ...

Sixty fabrics with elasticity were made up into two hundred fifty eight samples to evaluate the touch and pressure sensation in this paper. Twelve female were selected as subjects for wear trials. Nineteen physical parameters of fabrics were measured by ...

This paper describes image fusion in detail, and firstly intrudes the three basic levels which are pixel level, feature level and decision level fusion, and then compares with their properties and all other aspects. Then it describes the evaluation ...

With the recent evolution of network-based multiplayer games and the increasing popularity of online games demanding strict real-time interaction among players - like First Person Shooter (FPS) -, game providers face the problem to correlate network ...

This paper presents techniques for objective characterisation of Automatic Speech-to-Phoneme Alignment (ASPA) systems, without the need for human-generated labels to act as a benchmark. As well as being immune to the effects of human variability, these ...

In this paper, an objective way to evaluate artistic voice of singing is discussed. The authors take F1(the first Formant), F3(the third Formant), fundamental frequency, vocal range, perturbation of fundamental frequency, perturbation of F1, ...

In this paper, we present a novel objective approach to evaluate the disparity map quality. The two indices which are disparity gradient and disparity acceleration are first proposed for the evaluation of the disparity map. These two indices are under ...

This paper presents a novel, full-reference image quality measurement method for video quality assessment in television systems. Particularly, the proposed metric targets the problem of automatic assessment of digital picture degradations. The ...
