Claim:
1. A computer-implemented method for use in detecting an air pocket in a single crystal material, said method comprising: providing a matrix including a plurality of data units, the plurality of data units including image data related to a region of interest of the single crystal material; determining, by a processor, a difference between data units of the matrix and corresponding data units of the matrix, wherein the corresponding data units are defined by a first operation on the matrix performed about a first axis of the matrix; calculating, by the processor, a first index value based on the differences between data units of the matrix and corresponding data units of the matrix; calculating, by the processor, a second index value based on a second operation on the matrix, the second operation including one of a flip operation and a fold operation about a second axis of the matrix; and identifying an air pocket within the single crystal material based on the first index value, the second index value, and a predetermined threshold.
