Abstract
The characteristics of suspended sediment image can be reflected by the coefficients of biorthogonal wavelet transform of CDF(2,2). Based on the power distribution in different scales, an adaptive algorithm is proposed in this paper, whereby the coefficients are adjusted non-linearly. The particle information can be well retained while the useless background is removed. In this way, satisfactory binary image can be obtained for further analysis of the sediment particle.
