A Effective Geometric Flow Algorithm Using Leasting Perpendicular Project Length

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.
