| Abstract: | In this paper are given the decomposition and reconstruction of the image dyadic waveletand the study of the image sub-band enhancement algorithm based on the dyadic wavelet transform,with the focus on the design of the dyadic wavelet filters and on the the image decomposition level that influences the enhancement of the target edge in image.The dyadic wavelet transform is suitable for the enhancement of images since it has a shift-invariant property.The experiments results in that the dyadic wavelet enhancement in this paper can reduce the amplification of noise and achieve an excellent balance between the enhancement of subtle image detail and the avoidance of noise amplification. |
