摘要：A digital video target moving object segmentation method and system isdesigned for processing a digital video stream for segmentation of every target movingobject that appears in the video content. The proposed method and system is
characterized by the operations of a multiple background imagery extraction processand a background imagery updating process for extracting characteristic backgroundimagery whose content includes the motional background objects in addition to thestatic background scenes; and wherein the multiple background imagery extractionprocess is based on a background difference threshold comparison method, while thebackground imagery updating process is based on a background-matching and weight-counting method. This feature allows an object mask to be defined based on thecharacteristic background imagery, which can mask both the motional backgroundobjects as well as the static background scenes.
