    • There is a coding including-preparing coding units based on source pictures. The coding units are associated with largest coding tree units (LCTUs) which are polygons of source pictures. A tree format is utilized in processing the LCTUs into coding units. The preparing includes calculating an efficiency measure associated with a source picture position in a coordinate system based on fitting the coordinate system and the source picture with respect to each other. The preparing includes determining the source picture position based on a coding efficiency goal. The preparing includes determining padding areas. The source picture and padding areas are divided into LCTUs based on the coordinate system and the determined source picture position. The LCTUs are partitioned into coding units based on the tree format and a homogeneity rule. There is also a decoding including processing video compression data which is generated based on the coding units.
    • 存在基于源图像的包括准备编码单元的编码。 编码单元与作为源图像的多边形的最大编码树单元(LCTU)相关联。 利用树格式将LCTU处理成编码单元。 该准备包括基于将坐标系和源图像相对于彼此拟合来计算与坐标系中的源图像位置相关联的效率测量。 准备包括基于编码效率目标确定源图像位置。 准备包括确定填充区域。 源图像和填充区域根据坐标系和确定的源图像位置分为LCTU。 基于树格式和均匀性规则将LCTU划分为编码单元。 还包括处理基于编码单元生成的视频压缩数据的解码。
