Abstract
An object extracting method using a motion picture more accurately and rapidly extracts a specific object by using a difference image frame of a pair of still image frames obtained from a motion picture and color information which defines a color of the object. The object extracting method using a motion picture includes the steps of: obtaining a difference image frame by getting a pair of still image frames having a predetermined time interval from a motion picture and obtaining a color image frame which satisfies color information defining a color of a particular object from one of the still image frames; performing a grid processing of a logic image frame which is obtained from the difference image frame and the color image frame at a predetermined size and obtaining connected components using direction connection information and defining minimum areas each includes the connected components; comparing each of the minimum areas with predetermined conditions, thereby selecting the minimum areas which satisfy the conditions as object area candidates; and selecting and optimizing a largest object area candidate among the object area candidates.
