A critical and fundamental task in video mining is data preprocessing, in this paper, aimed to overcome limitations of redundant data for video mining, the paper propose a video mining preprocessing algorithm based on Rough Sets. Firstly, the representative data of video sequences is extracted in compressed domain. Secondly, the Information System Table is constructed by extracted representative data...
The material reserve can provide resources and support for handling unexpected natural disasters and public health emergencies. As the demands of material reserve are often changing in emergency events, this paper presents a dynamic planning model, which takes the minimum storage equipment investment, the minimum storage expenditure and material value loss, and the minimum shortage risk cost as multiple...
Based on rough sets (RS), an effective shot segmentation method is proposed in discrete cosine transform (DCT) compressed domain. First, DCT coefficients and DC coefficients are extracted from video sequences, and an information system is constructed with DC coefficient. Second, information system is reduced by reduction theory of RS, and the representation of the video frames is generated by reduced...
It is a challenging issue to analyze video content for video mining tasks due to lacking of effective representation of video. In this paper, we propose a novel key frame representation algorithm based on rough sets (RS) in discrete cosine transform (DCT) compressed-domain. Firstly, we extract DCT coefficients in compressed-domain, select and preprocess the DC coefficients that derived from DCT coefficients...
