摘要: We present a theoretical analysis of one-time key based phase scrambling for image matching using phase-only correlation (POC). Phase is used visual information protection templates. The effect on POC values analyzed. As result, the peak value, which as measure signal congruence, between nonscrambled signals can be estimated by observed with parameters. In addition, we indicate condition in value non-scrambled one parameter.
