Abstract: A scalable video encoding/decoding method and an apparatus thereof are provided to override an existing weight given in a slice unit to a corresponding block of an enhancement layer of a reference frame with a greater weight than the existing weight in forming the reference block of the enhancement layer when the video data of a macro block of a basic layer is in a skip mode, thereby improving efficiency of SVC(Scalable Video Coding). A scalable video encoding method comprises the following steps of: determining whether the block of a basic layer corresponding to the block of an enhancement layer of a current frame to encode is in a skip mode(S210); overriding an existing weight set in the block of the enhancement layer of a reference frame corresponding to the block of the enhancement layer of the current frame with a new weight when the block of the basic layer is in the skip mode(S220); and generating a reference block for the block of the enhancement layer of the current frame based on the block of the enhancement layer of the reference frame and the block of the basic layer of the current frame by using the new weight(S230).

Abstract: A method for scalable encoding of video data and an apparatus thereof are provided to override an existing weight value given in a slice unit with a greater weight when the reference block of an enhancement layer is generated if the video data of a macro block of a base layer is in a skip mode, thereby improving efficiency of the scalable video encoding. A method for scalable encoding of video data comprises the following steps of: generating a reference block by using a weight set for a corresponding block when the video data of a macro block can be predicted from the video data of reference pictures for the video data of the macro block(220); and generating the reference block by using a weight given to a slice belonging to a current frame when the video data of the macro block can not be predicted from the video data of the reference pictures.

Abstract: PURPOSE: A method of interpreting a document image area is provided to extract connected components to group the connected components as tree structures according to spacial relations, and to readjust the components in a text area via separating/combining procedures, thereby efficiently interpreting a document structure. CONSTITUTION: Connected components are analyzed through a reduced document image(61, 62). A tree is generated by an analyzed result of the connected components, to classify the connected components(63, 64). Text factors are grouped according to spacial relations from the classified connected components. A text block is readjusted through separation/combination procedures of the connected components. The step of generating the tree and classifying the connected components comprises the steps as follows. The tree is constructed from types of the connected components. Connected components including tables, frames, and pictures are grouped as independent nodes with text. Connected components within a text block surrounded by margins are grouped. Nodes which are not grouped are classified by areas of the connected components.
