Abstract: A method for generating codes for a code mask is provided. A plurality of symbols may be arranged into an n1 by n2 symbol structure, where n1 and n2 are integer values. A plurality of codewords may be defined from different overlapping k1 by k2 windows within the symbol structure, wherein co-linear and spatially overlapping windows define unique codewords, and the codewords are unique in a first direction of the symbol structure but are repeated in a second direction that is perpendicular to the first direction. A plurality of the symbol structures as a code mask, wherein symbols in two adjacent k1 by k2 windows are selected so as to avoid codeword aliasing of codewords in the two adjacent k1 by k2 windows.

Abstract translation: 提供了一种用于生成代码掩码代码的方法。 多个符号可以被排列成n1乘n2符号结构，其中n1和n2是整数值。 可以在符号结构内从不同重叠的k1乘以k2窗口来定义多个码字，其中，共线和空间重叠的窗口定义唯一的码字，并且码字在符号结构的第一方向上是唯一的，但是在第二个 方向垂直于第一方向。 多个符号结构作为代码掩码，其中选择两个相邻k1乘k2窗口中的符号，以避免两个相邻k1乘以k2窗口的码字的码字混叠。
