PURPOSE: A method for compressing an image using a dual object detection and motion trajectory information in steps of encoding and decoding the image is provided to extract image information, motion information, and transformation information for an object from an encoding process, and to reconfigure a prediction frame using the motion information and the transformation information for the object extracted on the basis of a reference frame in a decoding process, thereby raising a compression rate. CONSTITUTION: A method for compressing an image using a dual object detection and motion trajectory information in a step of encoding the image includes; a step of extracting an object with separating the object and a background from a reference frame in the image; and a step of extracting the object, the initial location value and the size of a block adjacent to the object, and the motion trajectory information of the object.

Abstract:
PURPOSE: An encoding method which applies an intra prediction of a macro block variable size division mode and a device thereof are provided to reduce an error of pixel values of a macro block by processing a calculation mode of a representative pixel value of the corresponding macro block in case of applying the intra prediction in a variable size macro block compression mode of a P frame. CONSTITUTION: In case the horizontal and vertical sizes of a macro block are the same or less than a standard size, an encoding device calculates the average value of the macro block and sets up the representative value of the macro block(S520,S522,S529). In case the horizontal and vertical sizes exceed the standard size or at least one of the sizes exceeds the standard size, the device calculates an average value about each minor macro block which is generated by the division of the macro block and sets up a representative value about each of the minor macro block(S530,S532,S526).
