    Image quality evaluation method base on digital wavelet transform and vision weighted by JIANG Ming1, MA Zhao-feng1, XIN Yu3, NIU Xin-xin1, YANG Yi-xian1

    Published 2011-01-01
    “…A new objective method WVWPSNR(wavelet and vision weighted peak signal noise ratio) was presented.In which the method was based on DWT,and the sensitivity of HVS(human visual system) was weighted using sub-band division.In this method,the assessment valued of the new method accord with MOS(mean opinion score).In order to demonstrate the effectiveness and to verify the reliability of WVWPSNR method,a series of experiment for JPEG、JPEG2000、White Noise、Gaussian Blur and FastFading images were made and tested.The results suggest that the proposed method can provide accurate measures of image quality under JPEG compression.…”

    A Note on Directional Wavelet Transform: Distributional Boundary Values and Analytic Wavefront Sets by Felipe A. Apolonio, Daniel H. T. Franco, Fábio N. Fagundes

    Published 2012-01-01
    “…By using a particular class of directional wavelets (namely, the conical wavelets, which are wavelets strictly supported in a proper convex cone in the k-space of frequencies), in this paper, it is shown that a tempered distribution is obtained as a finite sum of boundary values of analytic functions arising from the complexification of the translational parameter of the wavelet transform. …”
