This paper describes a physics-based technique for protecting the privacy of people in videos as defined by the MediaEval 2013 Visual Privacy task. We propose a physics-based approach which estimates the full spectrum of the surface spectral reflectance from the video. Whereby the wavelength which corresponds to the global minimum of the spectral curve (an intrinsic feature of the material) at ...

This paper addresses the problem of automatically partitioning a video into semantic segments using visual low-level features only. Semantic segments may be understood as building content blocks of a video with a clear sequential content structure. Examples are reports in a news program, episodes in a movie, scenes of a situation comedy or topic segments of a documentary. In some video genres l...

Content Distribution Networks (CDNs) attempt to improve Web performance by delivering Web content to end-users from servers located at the edge of the network. An important factor contributing to the performance improvement is the ability of a CDN to select servers in the proximity of the requesting clients. Most CDNs today use the Domain Name System (DNS) to make such server selection decision...

The W3C Web Content Accessibility Guidelines (WCAG) provide guidance on making websites accessible to people with disabilities. WCAG 1.0 focused largely on coding requirements that enable websites to interoperate with assistive technologies used by people with disabilities. WCAG 2.0 addresses an environment where website complexity has increased significantly due to higher network bandwidth and...

understanding of physiological responses of salt tolerance might be lead to identify main salt tolerance mechanisms and essential approaches for improving grain yield stability, and also to select salt tolerant wheat cultivars. thus, the effects of salinity were investigated on grain yield and some of the characteristics related to salt tolerance. six wheat cultivars (roshan, kavir, karchia, ga...

This paper presents a DSVL that simplifies educational video game development for educators who do not have programming backgrounds. Other solutions that reduce the cost and complexity of educational video game development have been proposed, but simple to use approaches tailored to the specific needs of educators are still needed. We use a multidisciplinary approach based on visual language an...

This paper introduces a framework that aims to support the design and development of mobile services. The traditional innovation process and its supporting instruments in form of creativity tools, acceptance research and user-generated content analysis are screened for potentials for improvement. The result is a reshaped innovation process where acceptance research and usergenerated content ana...

Studies suggest that self-harm users found it easier to discuss self-harm-related thoughts and behaviors using social media than in the physical world. Given the enormous and increasing volume of social media data, on-line self-harm content is likely to be buried rapidly by other normal content. To enable voices of self-harm users to be heard, it is important to distinguish self-harm content fr...

In this survey we will present the basic idea behind the contentbased image retrieval systems. We will present some low-level feature, techiques for matching similarity and we will conclude by giving basic ideas on semantic.

Web technology in an instructional environment is primarily dedicated to distributing course materials to supplement traditional classroom learning. It also uses designed intelligence to adapt to learners’ specific needs. The main purposes of this study were to construct and determine the efficiency of adaptive web-based instruction for LIS students. The web-based content was designed to adapt ...
