Video segmentation based on Consistency of multimedia communication campaign

摘要

proposed a motion-based video segmentation algorithm consistency.In a natural video sequence, the movements of different objects are different;we can use this in the proposed motion estimation algorithm to estimate the motion model step by step.In order to improve the reliability, the first use of the gray level information of the object frame image segmentation, get a set of regional.Models of different sports have different support area;support area under the motion model can be split out to its corresponding video object.To determine whether an area is the support of a regional movement model proposed by the average absolute displacement within the region as a support area of the frame difference criterion.For those small size mismatch region, a discriminant analysis, assigned to the neighborhood of a video object.
