摘要
研究了在实际应用中影响目标不变矩稳定性的各种因素 ,包括高斯模糊、有限观测区域和离散化处理等 .分析了在这些因素影响下不变矩的变化规律和误差 .并对离散条件下不变矩的误差进行了分析 .实验证明得出的具有模糊不变的不变矩 ,能对经过旋转比例变换且模糊的物体进行准确识别 .
Several important factors, including Gaussian blurring, finite imaging region, and discrete computation, were considered to study the stability of moment invariants in practical application. The effect and rules of each factor to the moment invariants were investigated. The stability of moment invariant on the discrete data case was analyzed. The experiments show that it is possible to recognize the blurred and rotated images accurately by the suggested invariants. All these researches will provide important theoretical and experimental foundations for practical imaging recognition systems.
