: Automatic annotation of Web image has great potential in improving the performance of web image retrieval. This paper presents a Broadcast Model (BM) for Web image annotation. In this model, pages are divided into blocks and the annotation of image is realized through the interaction of information from blocks and relevant web pages. Broadcast means each block will receive information (just l...

Retrieval practice has been shown to protect against the negative effects of previously learned information on the learning of subsequent information, while increasing retention of new information. We report three experiments investigating the impact of retrieval practice on false recall in a multiple list paradigm. In three different experimental designs participants studied blocks of interrel...

Availability of Huge image datasets and requirement of employing them causes necessity of effective methods for managing them. Extracting efficient features from images is one of the most important requirements in managing techniques such as image retrieval, indexing, classification, clustering and etc. Identifying the descriptive and discriminatory features is valuable and essential. In this p...

Background: Shared Pathology Informatics Network (SPIN) is a tissue resource initiative that utilizes clinical reports of the vast amount of paraffin-embedded tissues routinely stored by medical centers. SPIN has an informatics component (sending tissue-related queries to multiple institutions via the internet) and a service component (providing histopathologically annotated tissue specimens fo...

The color reduction in digital images is an active research area in digital image processing. In many applications such as image segmentation, analysis, compression and transmission, it is preferable to have images with a limited number of colors. In this paper, a color clustering technique which is a combination of a Kohonen Self Organized Featured Map (KSOFM) and a fuzzy clustering algorithm ...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

In this paper we compare techniques for storage and real-time retrieval of Variable Bit Rate (VBR) video data for multiple simultaneous users. The motivation for considering VBR is that video results in inherently time varying data, and as such, with the same average bit rate, higher quality can be achieved with VBR than with Constant Bit Rate (CBR). We propose and compare the following three c...
