摘要：
A method to encode and decode a halftone image such that the halftone image is efficiently compressed and decoded by using pattern characteristics of the halftone image includes determining different template shapes according to characteristics of the halftone image, compressing the halftone image based on determined template shape information, compressing the template shape information, and generating the compressed halftone image and the compressed template shape information as a bitstream.
