1. A method of encoding an image, the image comprising a plurality of rows of largest coding units (LCUs), the method comprising:
determining whether or not wavefront parallel processing is enabled;
partitioning the plurality of rows of LCUs to comprise a normal slice and a group of dependent slices, whereby, the normal slice comprises at least one LCU, and, the group of dependent slices comprises at least one LCU and consists of every dependent slice that uses information from a slice header of the normal slice for encoding;
restricting, based on the determination that wavefront parallel processing is enabled, the partitioning of the plurality of rows of LCUs such that a last LCU in the group of dependent slices belongs in a same row as a first LCU of the normal slice when the first LCU of the normal slice is not a first LCU of the row.
