Similarity Based Retrieval of Videos

Genre tagging of videos based on information retrieval and semantic similarity using WordNet

In this paper we propose a new approach for the genre tagging task of videos, using only their ASR transcripts and associated metadata. This new approach is based on calculating the semantic similarity between the nouns detected in the video transcripts and a bag of nouns generated from WordNet, for each category proposed to classify the videos. Specifically, we have used the Lin measure based ...

Color Difference Histogram for Feature Extraction in Video Retrieval

Content Based Video retrieval is another facet of Content Based Retrieval systems. It is to be noted that videos are far more complex than images as they are a sequence of changing images and audio tracks. Here the content of the videos itself is matched with the query of the user. Video retrieval consists of a series of steps such as segmentation, frame selection, feature extraction and simila...

A Robust Zero-Watermark Scheme with Similarity-based Retrieval for Copyright Protection of 3D Video

The copyright protection of 3D videos has become a crucial issue. In this study, a novel zero-watermark scheme with similarity-based retrieval is proposed. In our proposed scheme the features of both 2D-video and depth-map components are first extracted. Next, master shares and ownership shares are generated from these features and their relevant copyright information based on (2,2) visual secr...

Semantic Video Retrieval Using High Level Context

Video retrieval – searching and retrieving videos relevant to a user defined query – is one of the most popular topics in both real life applications and multimedia research. This thesis employs concepts from Natural Language Understanding in solving the video retrieval problem. Our main contribution is the utilization of the semantic word similarity measures for video retrieval through the tra...
