WebJun 12, 2024 · Both analysis transformation and synthesis transformation include three stages, as shown in Fig. 6. The synthetic transformation is similar to the inverse process of the analysis transformation. Analysis transformation includes convolution, down-sampling and activation function generalized normalization transformation (GDN) (Ballé et al. … WebNov 19, 2015 · We introduce a parametric nonlinear transformation that is well-suited for Gaussianizing data from natural images. The data are linearly transformed, and each component is then normalized by a pooled activity measure, computed by exponentiating a weighted sum of rectified and exponentiated components and a constant.

WebThe optimized transformation substantially Gaussianizes the data, achieving a significantly smaller mutual information between transformed components than alternative methods including ICA and radial Gaussianization. The transformation is differentiable and can be efficiently inverted, and thus induces a density model on images. WebMar 25, 2024 · [24] J.
