Human identification based on background subtracti
no vote
Background subtraction method is also called a background subtraction, background subtraction method is the difference to get moving with the background image of the current frame target range, the method can more frame difference method better identification and extraction of moving targets, is currently the most commonly used in motion segmentation method. But needs building a site background image, this site background image must not containing movement target, and should can constantly of update to adapted current background of changes, building background image of method has many, compared common of has based on single Gaussian model of background building, based on mixed Gaussian model of background building, based on in the value filter of background constructed, based on Kalman filter of background constructed, based on nuclear function density estimated of background model constructed.
