Illustrations tetra pattern based on one of four possible directions of each center pixel. (a) The directions of the center pixel based on (7). (b) Example of calculation of tetra pattern (see (8)-(9)) in the case of the center-pixel direction “1” defined from (7) using the direction of neighbors. Light wheat represents the direction of the center pixel and cyan represents its neighborhood pixels.
