A novel five-frame difference scheme for local change detection in underwater video
2017 Fourth International Conference on Image Information Processing (ICIIP)(2017)
摘要
This paper addresses the problem of local change detection in an underwater environment. A spatio-contextual framework based frame difference algorithm has been proposed, which uses five consecutive video frames to extract the object. This is a two-stage method. In the first stage, frame differencing is carried out using the spatio-contextual framework, whereas in the second stage a knowledge-based analysis is proposed to detect the moving objects region. The results obtained using the proposed method is compared with the existing background subtraction methods and found to be a far better approach. The performance of the proposed scheme is evaluated by the help of three evaluation measures, such as Precision, Recall, and F-measure.
