Abstract:
1. A method of decoding an image, the method comprising: when a first coding unit comprises a region that deviates from a boundary of the image to be decoded, splitting the first coding unit into a plurality of second coding units; when the first coding unit does not comprise the region that deviates from the boundary of the image, splitting the first coding unit into the plurality of second coding units, which comprises: wherein: the image is split into a plurality of maximum coding units according to information about a maximum size of a coding unit, a maximum coding unit, of the plurality of maximum coding units, is hierarchically split into one or more coding units of depths including at least one of a current depth and a lower depth, according to the split information, when the split information indicates a split for the current depth, the first coding unit of the current depth is split into four rectangular second coding units of the lower depth, independently from neighboring coding units, and when the split information indicates a non-split of the lower depth, one or more prediction units are obtained from a second coding unit of the lower depth.
