Visual Attention Key Frame Extraction for Video Annotations
نویسنده
چکیده
The insufficiency of labeled training data for representing the distribution of the entire dataset is a major obstacle in automatic semantic annotation of large-scale video database the objective is to represent the most “important” or “meaningful” scenes of the large amount of visual information by only a few images:the key frames. First, the image sequences are temporally segmented into continuous segments called shots.Then a few frames of each shot are selected as key frames.In this paper ,retrieving videos using key words requires obtaining the semantic features of the videos. Most work reported in the literature focuses on keyframe extraction methods in the video shot.The focus is on visual attention Keyframe extraction(VAKE). KeywordsVisual attention ,keyframe, time constraint clustering.

متن کاملAutomatic video summarization driven by a spatio-temporal attention model
According to the literature, automatic video summarization techniques can be classified in two parts, following the output nature: “video skims”, which are generated using portions of the original video and “key-frame sets”, which correspond to the images, selected from the original video, having a significant semantic content. The difference between these two categories is reduced when we cons...

This paper proposes a novel approach of dominant color based extraction of key frames for sports video summarization. The visual features have been used to obtain play field color shots and non-play field color shots. For the every play field color shots dominant colored key frame has been extracted using color histogram analysis and created video summary. This provides users a way to swiftly b...

OVERVIEW The objective of this component is to index videos based on semantic mid to high-level features. To achieve this, the component integrates different modules for video processing. As shown in the diagram, the component integrates the following components in order to extract the embedded semantics from the video: shot boundary detection for categorising shots with similar attributes; key...
