基于视觉与结构谱特征融合的视频检索
Video retrieval based on visual feature and structural spectral feature
摘要
Abstract
The time series structure is one of key characters of videos. In the paper, the method of abstraction and presentation video series feature is discussed which is based on DTW and graph spectral. DTW is used to extract some key frame images on the frame difference curves; the structure graph of video shot is constructed with the vertex set of the key frame images and edge set of the relation of these images. The video structure spectral is extracted by analyzing the the video structural graph's adjacent matrix. Visual feature and structral featrue are taken into consideration to rank the simility of the selected video clips. Experimental results show that the structrual spectral is able to present the video structural feature efficiently and can be used to retrieval the vido.关键词
