The increased in availability and usage of on-line digital video has created a need of automated video content analysis techniques, including indexing and retrieving. Automation of indexing significantly reduces the processing cost while by minimizing tedious work. Traditional video retrieval methods based on video metadata, fail to meet technical challenges due to large and rapid growth of multimedia data, demanding effective retrieval systems. One of the most popular solutions for indexing is extracting the features of video key frames for developing a Content Based Video Retrieval (CBVR) system. CBVR works more effectively as these deals with content of video rather than video metadata. Various features like color, texture, shape can be integrated and used for video indexing and retrieval.Implemented CBVR system is experimented based on integration of texture, color and edge features for video retrieval. Entropy is a texture descriptor used for key frame extraction and video indexing. However entropy, color (RGB) and edge detection algorithms are used for video retrieval. These features are combined in various ways like entropyedge, entropy-color for result refinement. Dataset is created with the videos from different domains like e-learning, nature, construction etc. By the combination of these features in different ways, we achieved comparative results. Obtained result shows that combining of two or many features gives better retrieval.
From the last decade the Multi/Rich Media information production and usage is growing extremely. Video is the most informative and challenging as it is a combination of all other
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
