Knowledge Based Methods for Video Data Retrieval

Thanga Ramya, Rangarajan
2011 International Journal of Computer Science & Information Technology (IJCSIT)  
Then the focus of this paper is towards stochastic methods and also demonstrates how HMMs and DBNs can be effectively used for content-based video retrieval from multimedia databases.  ...  Large collections of publicly available video data grow day by day, the need to query this data efficiently becomes significant.  ...  These techniques exploit automatic learning capabilities to derive knowledge and avoid the need for an expert as well as reduce the retrieval time.  ...

Using manual and automated annotations to search images by semantic similarity

João Magalhães, Stefan Rüger
2010 Multimedia tools and applications  
However, for full rank measures (MAP) in the real datasets (Flickr) retrieval by semantic similarity with automatic annotations is similar or better than amateur-level manual annotations.  ...  More specifically, we study the accuracy of manual annotations versus automatic annotations, the influence of manual annotations with different accuracies as a result of incorrect annotations, and revisit  ...  must generate the query description in a fixed amount of time and with a low computational cost.  ...

Properties of optimally weighted data fusion in CBMIR

Peter Wilkins, Alan F. Smeaton, Paul Ferguson
2010 Proceeding of the 33rd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '10  
Content-Based Multimedia Information Retrieval (CBMIR) systems which leverage multiple retrieval experts (En) often employ a weighting scheme when combining expert results through data fusion.  ...  Because of the large number of potential weights, existing approaches impose a hierarchy for data fusion, such as uniformly combining query image results from a single retrieval expert into a single list  ...  For our investigation we performed 'fully automatic' retrieval which processes a query with no human intervention.  ...

Retrieval of multimedia stimuli with semantic and emotional cues: Suggestions from a controlled study [article]

Marko Horvat, Davor Kukolja, Dragutin Ivanec
2017 arXiv   pre-print
Accuracy and speed of the multimedia retrieval process depends on the chosen metadata annotation model.  ...  The quality of such multifaceted retrieval is opposed to the potential complexity of data setup procedures and development of multimedia annotations.  ...  Retrieval of loosely annotated data, with only one expert-defined tag per picture, is even more open to errors than with, for example, social media with community generated tags, hashtags or folksonomies  ...
