This document proposes a semantic content extraction system for videos using a fuzzy ontology and rule-based model. The system allows users to automatically query and retrieve objects, events, and concepts extracted from videos. It introduces an ontology-based fuzzy video semantic content model that uses spatial and temporal relations in event and concept definitions. This model provides a standard for constructing domain ontologies and additional rules to define complex situations and lower computational costs. The framework has been implemented and tested across three domains, achieving satisfactory precision and recall for object, event, and concept extraction.

AUTOMATIC SEMANTIC CONTENT EXTRACTION IN VIDEOS USING
A FUZZY ONTOLOGY AND RULE-BASED MODEL
ABSTRACT:
Recent increase in the use of video-based applications has revealed the need for extracting the
content in videos. Raw data and low-level features alone are not sufficient to fulfill the user 's
needs; that is, a deeper understanding of the content at the semantic level is required. Currently,
manual techniques, which are inefficient, subjective and costly in time and limit the querying
capabilities, are being used to bridge the gap between low-level representative features and high-
level semantic content.
We propose a semantic content extraction system that allows the user to query and retrieve
objects, events, and concepts that are extracted automatically. We introduce an ontology-based
fuzzy video semantic content model that uses spatial/temporal relations in event and concept
definitions. This metaontology definition provides a wide-domain applicable rule construction
standard that allows the user to construct ontology for a given domain.
In addition to domain ontologies, we use additional rule definitions (without using ontology) to
lower spatial relation computation cost and to be able to define some complex situations more
effectively. The proposed framework has been fully implemented and tested on three different
domains. We have obtained satisfactory precision and recall rates for object, event and concept
extraction.

An Intelligent Approach for Effective Retrieval of Content from Large Data Se...

IJCSIS Research Publications

The advents in this technological era have resulted into enormous pool of information. This information is stored at multiple places globally, in multiple formats. This article highlights a methodology for extracting the video lectures delivered by experts in the domain of Computer Science by using Generalized Gamma Mixture Model. The feature extraction is based on the DCT transformations. In order to propose the model, the data set is pooled from the YouTube video lectures in the domain of Computer Science. The outputs generated are evaluated using Precision and Recall.

Content based video retrieval using discrete cosine transform

nooriasukmaningtyas

A content based video retrieval (CBVR) framework is built in this paper. One of the essential features of video retrieval process and CBVR is a color value. The discrete cosine transform (DCT) is used to extract a query video features to compare with the video features stored in our database. Average result of 0.6475 was obtained by using the DCT after implementing it to the database we created and collected, and on all categories. This technique was applied on our database of video, check 100 database videos, 5 videos in Keywords: each category.

Coronary heart disease is a disease with the highest mortality rates in the world. This makes the development of the diagnostic system as a very interesting topic in the field of biomedical informatics, aiming to detect whether a heart is normal or not. In the literature there are diagnostic system models by combining dimension reduction and data mining techniques. Unfortunately, there are no review papers that discuss and analyze the themes to date. This study reviews articles within the period 2009-2016, with a focus on dimension reduction methods and data mining techniques, validated using a dataset of UCI repository. Methods of dimension reduction use feature selection and feature extraction techniques, while data mining techniques include classification, prediction, clustering, and association rules.

Key frame extraction is an essential technique in the computer vision field. The extracted key frames should brief the salient events with an excellent feasibility, great efficiency, and with a high-level of robustness. Thus, it is not an easy problem to solve because it is attributed to many visual features. This paper intends to solve this problem by investigating the relationship between these features detection and the accuracy of key frames extraction techniques using TRIZ. An improved algorithm for key frame extraction was then proposed based on an accumulative optical flow with a self-adaptive threshold (AOF_ST) as recommended in TRIZ inventive principles. Several video shots including original and forgery videos with complex conditions are used to verify the experimental results. The comparison of our results with the-state-of-the-art algorithms results showed that the proposed extraction algorithm can accurately brief the videos and generated a meaningful compact count number of key frames. On top of that, our proposed algorithm achieves 124.4 and 31.4 for best and worst case in KTH dataset extracted key frames in terms of compression rate, while the-state-of-the-art algorithms achieved 8.90 in the best case.

Embracing GenAI - A Strategic Imperative

Peter Windle

Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction. This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
