    Abstract: A method and apparatus for implementing cloud computing by efficiently encoding a display screen between a cloud server and a client terminal. The method for encoding a cloud display screen in the cloud server, includes: acquiring region information of currently generated windows based on an application programming interface (API) function information of an Operating System (OS); extracting relative depth information between each of the currently generated windows from the OS; generating an encoding mode map in which an entire screen is divided into a plurality of blocks, based on the acquired region information and the extracted relative depth information; and encoding each of the plurality of blocks based on the generated encoding mode map.

    Abstract: Provided are binary image encoding and decoding methods and binary image encoding and decoding apparatuses using an adaptive template. The binary image encoding method includes: applying a window having a predetermined size and shape to a predetermined number of previous pixels and peripheral pixels of the previous pixels, and acquiring correlations between the previous pixels and the peripheral pixels within the window; determining relative locations having high correlation with the previous pixels within the window based on the acquired correlations; generating a template based on the determined relative locations; and performing binary arithmetic encoding on a current pixel by using the generated template.
