    Abstract: A composite ceramic core that, in combination with a shell mold, is suitable for use in a casting process to produce metal alloy components. The core and casting process make use of a highly leachable interior layer in combination with an exterior layer that is less reactive than the interior layer in the presence of common alloying elements. The interior layer contains at least one hollow channel that allows a point of entry for a leaching solution, as well as exit for gaseous byproducts generated during the casting process.

    Abstract: Three block concepts are introduced in HEVC: coding unit (CU), prediction unit (PU), and transform unit (TU). The overall coding structure is characterized by the various sizes of CU, PU and TU in a recursive fashion. For transform processing in current HEVC, a hierarchy RQT (Residual Quad Tree) is used and the TU size is related to the CU size, but independent of the PU size. This results in high encoding complexity and also causes increased processing time to process the syntax of residual quad tree. Accordingly a modified transform unit partition with reduced complexity is disclosed. According to an embodiment, the TU size may be restricted to the minimum of PU width and height, except for a 2N×2N coding unit with the 2N×2N partition type. In another embodiment, the maximum TU size equals to maximum of PU width and height, and the minimum TU size equals to minimum of the PU width and height, except for a 2N×2N coding unit with the 2N×2N partition type. In yet another embodiment, the TU size is selected between 2N×2N and N×N for the 2N×2N, 2N×N, N×2N and N×N partition types. The syntax element, split_transform_flag, is used to indicate the selection of 2N×2N or N×N TU size when needed. Furthermore, a method with reduced complexity of selecting the best merge candidate for the 2N×2N CU merge mode is disclosed. The method relies on R-D cost associated with the motion vector of merge candidate to reduce required computation.

    Abstract translation: 在HEVC中引入了三个块概念：编码单元（CU），预测单元（PU）和变换单元（TU）。 总体编码结构的特征在于以递归方式各种尺寸的CU，PU和TU。 对于当前HEVC中的变换处理，使用层次RQT（残余四叉树），并且TU大小与CU大小相关，但与PU大小无关。 这导致高编码复杂度，并且还导致处理剩余四叉树语法的处理时间增加。 因此，公开了具有降低的复杂性的修改的变换单元分区。 根据实施例，除了具有2N×2N分区类型的2N×2N编码单元之外，TU大小可以被限制为PU宽度和高度的最小值。 在另一个实施例中，除了具有2N×2N分区类型的2N×2N编码单元之外，最大TU大小等于PU宽度和高度的最大值，并且最小TU大小等于PU宽度和高度的最小值。 在另一个实施例中，对于2N×2N，2N×N，N×2N和N×N个分区类型，在2N×2N和N×N之间选择TU大小。 语法元素split_transform_flag用于在需要时指示2N×2N或N×N TU大小的选择。 此外，公开了一种选择2N×2N CU合并模式的最佳合并候选的复杂度降低的方法。 该方法依赖于与合并候选的运动矢量相关联的R-D成本来减少所需的计算。

    Abstract: A method performs inverse tone mapping of an image in a decoder. For each block of each color channel of the image a scaling factor is determined by adding a predicted scaling factor for the current block to a difference between the predicted scaling factor and the scaling factor of an adjacent block. An offset value for the current block is determined by adding a predicted offset for the current block to a difference between the predicted offset value and the offset value of the adjacent block. The scaling factor and the offset value are applied to pixel intensity values of the current block to produce a mapped block. The inverse tone mapping can also be applied to blocks of different sizes.
