With the rapid development of internet, mobiles, and social image-sharing websites, a large number images are generated daily. The huge repository poses challenges for an image retrieval system. On websites such as Flickr, users can assign keywords/tags to which describe content images. These tags play important role in However, user-assigned highly personalized brings many Thus, it is necessar...

Face recognition is one of the most successful applications in the field of image processing. Most robust face methods are difficult to improve their performance under certain environments. The paper proposes a method for robust face recognition and implementing a tagging process in video surveillance. It provides an interface for communicating with camera or webcam capturing images storing and...

Completely Automated Public Turing Tests to Tell Computers and Humans Apart (CAPTCHAs) are the automatic filters that are widely used these days to disallow any automated script that can perform the work of a human. CAPTCHAs are built in such a way that it is very difficult for any automated script to break them. In this paper, a novel approach for EZ-Gimpy CAPTCHAs has been proposed that first...

Human observer can understand the contents of image and can do object based enhancementmanually based on their perceptual understanding. Existing photo applications use low leveldescription for performing similar tasks. However, there is gap between the output ofoperations by application and same task performed by human being. To bridge this gap,objects must be identified by pho...

Joan Beaudoin is a doctoral student at Drexel University. She can be reached by email at jeg56drexel.edu. T he development and subsequent popularity of image tagging at sites such as Flickr (www.flickr.org) has been a phenomenon to receive considerable attention over the course of the last few years. After spending more than a decade cataloging and providing access to images in an academic ...

Cardiovascular magnetic resonance (CMR) tagging has been established as an essential technique for measuring regional myocardial function. It allows quantification of local intramyocardial motion measures, e.g. strain and strain rate. The invention of CMR tagging came in the late eighties, where the technique allowed for the first time for visualizing transmural myocardial movement without havi...
