Patent ID: 8238605

Claim:
A digital video target moving object segmentation method for processing an input video stream whose content shows the scene of a monitored locality having the presence of a static background scene, a motional background object, and a target moving object; the digital video target moving object segmentation method comprising: processing the input video stream based on a background difference threshold comparison method for producing background imagery of the monitored locality; updating the background imagery based on a background-matching and weight-counting method for producing updated background imagery whose content includes the motional background object in addition to the static background scene; and producing an object mask based on the updated background imagery, wherein the object mask defines an unmasking portion for the target moving object and a masking portion for both the static background scene and the motional background object, and wherein the object mask is superimposed to the current frame of the input video stream for displaying the target moving object while masking the static background scene and the motional background object.
