【摘要】 为改进光学小波变换,提出了光学可分离小波变换的概念。通过对光学小波变换的必要条件进行分析,采用层叠算法和二维可分离小波变换构造方法计算出了尺度和小波函数的二维离散近似序列。将新的母小波引入到光学小波变换中,获得了光学可分离小波变换。通过与现有光学小波变换及二维可分离离散小波变换进行比较说明了其优点。更多还原

【Abstract】 For improving optical wavelet transform(OWT),optical separable wavelet transform(OSWT) is proposed.Based on the analysis of the necessary condition for OWT,using the cascade algorithm and 2D separable wavelet transform scheme,discrete approximation sequence of scaling and wavelet functions was computed for optical implementation.The advantages of OSWT are described via comparison with OWT and 2D discrete separable wavelet transform.更多还原
