In this Keynote Address paper, we review early work on Image and Video Quality Assessment against the backdrop of an interpretation of image perception as a visual communication problem. As a way of explaining our recent work on Video Quality Assessment, we first describe our recent successful advances on QA algorithms for still images, specifically, the Structural SIMilarity (SSIM) Index and t...

Private karaoke rooms (known as “KTV” or karaoke television) are a special type of leisure space in Taiwan. The focus of this study is to show the relationship between service quality, brand image, customer satisfaction, and customer loyalty in the KTV industry. This study examines two chain KTV operations in Taiwan, with two locations for each chain; the study comprises a total of 255 valid qu...

The assessment of image quality is important in numerous image processing applications. Two prominent examples, the Structural Similarity Image (SSIM) index and Multi-scale Structural Similarity (MS-SSIM) operate under the assumption that human visual perception is highly adapted for extracting structural information from a scene. Results in large human studies have shown that these quality ind...

The Structural Similarity (SSIM) Index is a very popular image quality assessment algorithm due to its good performance and simple calculation. This paper analyzes the influence of the smooth region on the performance of SSIM. It was found out that SSIM tends to depend on the quality of the smooth region to assess the quality of the whole image. From analysis by means of the SSIM quality map, w...

Choiceboard technology is increasingly being offered in e-commerce environments. This technology allows customers to configure their products and services by choosing from a menu of attributes, components, delivery options, and prices. This paper examines, in the context of a choiceboard environment, the impact of system and information quality, and information presentation on information and d...

When encryption and authentication techniques are applied to image or video data, sometimes it is advantageous to limit the operation to the DC DCT coefficient of each 8× 8 block in a picture. In this work, the performance of such an approach is evaluated. This problem is considered as an image quality problem, and the metric structural similarity is used to show that by authenticating the DC c...

No-reference image quality assessment needs no prior knowledge of reference image. A new fuzzy image quality measure (built from interval type-2 fuzzy sets (IFS2)) is compared with experimental psycho-visual data. The proposed measure is based on IFS2 entropy applied on synthetic images. A recently performed psycho-visual experiment provides psycho-visual scores on some synthetic images, and co...

In recent years, a social networking service (SNS) not only thrives in digital content industries but also functions as a platform that focuses on facilitating the building of social interactions among people. Based on the DeLone and McLean model (2003), this study develops a modified model to examine the effect of the three website technology characteristics on user satisfaction, benefits of s...

The purpose of this paper is to extend the theory of task/technology fit by exploring the impact of different technology characteristics on performance of preference and intellective tasks in an inter-group context. The authors tested 80 participants on group performance using a 2x2 factorial design with task type and mode of collaboration as the independent variables. Structural equation model...

This study examined the attitudes of employees working in Indian hotels catering to tourists. It analyzed their perception of training opportunities and the impact of such training on the service provided to guests. An integrated model was developed highlighting the relationship between perceived accessibility to training, perceived support for training, perceived benefits from training, and th...
