      Processing algorithmTechnical principleSpecificityAdvantageDisadvantage
      Roundness and eccentricityUtilizing the characteristics of cat’s eye reflection points to distinguish and identify cat’s eye targetsGradient Characterization of Cat’s Eye Echo SpotsUnder the condition of low contrast, it can realize the detection and recognition of cat’s eye photoelectric equipmentPoor detection capability for high-speed moving targets
      SFDCRecognition of cat’s eye targets using the distribution of gray value changes in the echo image and the modulation frequency of the pulsed laserBeam frequency modulation information for laser active illumination of catadioptric targetsThe dual-criterion method is more scientifically accurate than the single-criterion method in recognizing cat’s eye targets from dynamic backgroundsPoor real-time detection capability
      SPCSRemoving dynamic background and transforming traditional target recognition into measurement vector processingCat’s eye effect target information as a sparse signal reconstructed with compressed perception theoryLow data storage and fast runtime for dynamic background detectionHigher error rate when recognizing kitty eye targets
      MSPFRecognition detection by suppressing the background and enhancing the targetCombines traditional cat’s eye target recognition and selective features of visual attentionHas a high recognition rate and low false recognition rateNot suitable for detecting moving targets
