First, the watermarking process generally requires an increase in one magnitude but a decrease in the other for each pair. As the energy of each color component remains roughly balanced, modifications of a pair of DCT coefficients in adjacent locations with the same color are expected to yield ...
As these data were all captured in the hot summer, and the shooting distance was more than 5 km, the turbulence effect of the images was significant. From the human eye visual perception analysis, the output results of the Gao et al. network appeared distorted (see the first to third ...
Therefore, the real turbulence degradation process is extremely complex [4–6]. However, in some turbulent image restoration literature, it is considered that the point spread function (PSF) of atmospheric turbulence is time- and space-invariant. Based on this view, the degradation process of ...
Recently, an attempt was made to approximate the convolutional noise pdf differently than with the Gaussian one in order to obtain improved equalization performance. In [4], the maximum entropy density approximation method [1,2,45,46] and Lagrange multipliers up to order four were used to ...

In addition, her mother was highly attuned to her needs and was regularly engaged in extended family and community support systems. While this nonrandom participant selection of course precludes generalizations, in this exploratory study we have chosen a different goal, one of rich description of ...
