摘要
An apparatus and method for optical flow and sensor input based background subtraction in video content, includes one or more processors configured to compute a plurality of first motion vector values for a plurality of pixels in a current image frame with respect to a previous image frame using an optical flow map. A plurality of second motion vector values are computed for the plurality of pixels in the current image frame based on an input received from a sensor provided in the apparatus. A confidence score is determined for the plurality of first motion vector values based on a set of defined parameters. One or more background regions are extracted from the current image frame based on the determined confidence score and a similarity parameter between the plurality of first motion vector values and the plurality of second motion vector values.
