摘要

Aiming at the high time complexity problem of extracting optimal geometric flow in second generation bandelet transform, a effective method based on leasting perpendicular project length is proposed. At first, performing non-separable wavelet transform to obtain wavelet coefficient, on which extracting optimal geometric flow through the method of second generation bandelet transform. Theoretical analysis and experimental results show that the proposed scheme can reduce time complexity of the scheme and extract robust and accurate geometric flow.%在对二维紧支撑不可分离小波与第二代Bandelet变换的研究基础上,针对第二代Bandelet变换提取几何流的高时间复杂度的问题,提出了一种基于最小化垂直投影区间的行之有效的提取最佳几何流的方法.实验结果表明该算法具有提取图像几何流.有较强的稳健性和较高的精确性,且能降低算法的时间复杂度.
