1. A method for analyzing two-dimension (2D) dual-differential sensing information, comprising:

  • obtaining a 2D dual-differential sensing information including a plurality of dual differences, wherein each of the dual differences is a difference of a first difference for a first pair of signal values and a second difference for a second pair of signal values, wherein the first pair of signal values include a first signal and a second signal, the second pair of signal values include the second signal and a third signal, wherein the first signal, the second signal and the third signal are generated simultaneously from three sensors parallel to each other; and

    analyzing the 2D dual-differential sensing information to determine each partial sensing information with inner low values within outer high values in the 2D dual-differential sensing information.
