Abstract: Single pixel edges or figure are needed for border recognition in the field of 3D garment human body modeling.Integration of multi-scale plays an important role in step-form edge detection used by wavelet transform.In this paper，a method was applied to determine the double thresholds adaptively based on the histogram of the local maxima.Then，by restraint of local no-maxima to further edge thinning，and linking edge points to attack edge discontinuity using the double thresholds，the suitable human figure image can be detected.The experimental results showed this algorithm is feasible and effective.
