In this paper, we propose a method for dynamic integration of TV-program content and related web content and demonstrate our prototype system called WebTelop . The primary source of information in WebTelop is the TV-program content. Web pages related to the TV-program content are retrieved automatically in real time and are used to augment the TV-program content in the form of captions. Our met...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
until now many studies have been done over recent decades throughout the world to show the right age to start english. in iran, research is still at an early stage in terms of evaluating teachers’ beliefs about teaching children english. the problem of at what age to start teaching english and how to teach english to elementary school children has not been solved neither in this country nor els...
This paper discusses the main aspects regarding the performance gap in Content-based Image Retrieval (CBIR) systems, which is an important issue regarding their acceptability. We also detail the main problems that lead to the performance gap: the use of many features to represent images, the lack of appropriate indexing structures for images and features, deficient query plans employed to execu...
Feature relevance estimation is one of the most successful techniques used for improving the retrieval results of a content-based image retrieval (CBIR) system based on users’ feedbacks. In this class of approaches, the weights of the feature elements (FEs) are adjusted based on the relevance feedbacks (RFs) given by the users to reduce the socalled semantic gap in the underlying CBIR system. A...
Background: The Family Physician Program, one of the most important efforts of the Iran health system to establish a referral system, was developed and implemented in several provinces, but it faced challenges due to several reasons that prevented the program's progress. So This study was conducted to analyze the family physician program to identify the causes and challenges of the program fail...
E-Commerce Web based applications designed to facilitate Data-exchange collaboration are enjoying growing popularity. In the next few years, business companies will want their web resources linked to ontological content –because of the many powerful tools that will be available for using it by potential customers. Thus, product information will be exchanged between applications, allowing comput...
This chapter discusses key aspects concerning the performance of Content-based Image Retrieval (CBIR) systems. The so-called performance gap plays an important role regarding the acceptability of CBIR systems by the users. It provides a timely answer to the actual demand for computational support from CBIR systems that provide similarity queries processing. Focusing on the performance gap, this...
In content-based image retrieval (CBIR) using feedback-based learning, the user marks the relevance of returned images and the system learns how to return more relevant images in a next iteration. In this learning process, image comparison may be based on distinct distance spaces due to multiple visual content representations. This work improves the retrieval process by incorporating multiple d...
In most content-based image retrieval systems, colors are used as very significant feature for indexing and retrieval purposes. Many of them use the quantized colors for various reasons. In some systems, especially the systems accepting user-drawn queries, color quantization improves the overall performance as well as the execution time. In this paper, a new color quantization method, which use...
