    • Print image processing includes generating (402, 408) a first direction image and a multi-resolution hierarchy tree (MRT) having a plurality of direction measures, and adjusting (4120 at least one direction measure based on whether it is associated with a singularity area or a non-singularity area of the MRT, to output (418) a final first direction image used for further print image processing. The MRT direction images include the first direction image having a highest resolution and at least one other direction image having a lower resolution. Each direction measure is determined from a direction measure, in a higher resolution direction image, which is selected based on image quality and distance from the boundary between print areas and non-print areas. Upon determining the final first direction image, a consistency measure can be computed and compared to a consistency metric and the method iteratively performed until the consistency measure satisfies the consistency metric.
    • 打印图像处理包括生成(402,408)第一方向图像和具有多个方向测量值的多分辨率分层树(MRT),以及基于其是否与奇异区域相关联来调整(4120)至少一个方向测量 或MRT的非奇异区域,以输出(418)用于进一步的打印图像处理的最终的第一方向图像。MRT方向图像包括具有最高分辨率的第一方向图像和具有较低分辨率的至少一个其他方向图像 分辨率,每个方向测量是根据方向测量确定的,在更高分辨率的方向图像中,根据图像质量以及与打印区域和非打印区域之间的边界的距离来选择更高分辨率的方向图像;在确定最终的第一方向图像时, 度量可以被计算并且与一致性度量进行比较,并且该方法迭代地执行,直到一致性度量满足一致性度量。
