Affine transformation, layer blending, and artistic filters are popular processes that graphic designers employ to transform pixels of an image to create a desired effect. Here, we examine various approaches that synthesize new images: pixel-based compositing models and in particular, distributed representations of deep neural network models. This paper focuses on synthesizing new images from a learned representation model obtained from the VGG network. This approach offers an interesting creative process from its distributed representation of information in hidden layers of a deep VGG network i.e., information such as contour, shape, etc. are effectively captured in hidden layers of neural networks. Conceptually, if $Φ$ is the function that transforms input pixels into distributed representations of VGG layers ${\bf h}$, a new synthesized image $X$ can be generated from its inverse function, $X = Φ^{-1}({\bf h})$. We describe the concept behind the approach, present some representative synthesized images and style-transferred image examples.
