Evolutionary search has been extensively used to generate artistic images. Raw images have high dimensionality which makes a direct search for an image challenging. In previous work this problem has been addressed by using compact symbolic encodings or by constraining images with priors. Recent developments in deep learning have enabled a generation of compelling artistic images using generativ...

Collages have been a common form of artistic expression since their first appearance in China around 200 BC. Recently, with the advance of digital cameras and digital image editing tools, collages have gained popularity also as a summarization tool. This paper proposes an approach for automating collage construction, which is based on assembling regions of interest of arbitrary shape in a puzzl...

Continuous tone images must be halftoned to be displayed on binary output devices such as printers. The ordered dither algorithm is a popular approach to halftoning. This algorithm uses a threshold matrix to approximate gray scale values. The arrangement of thresholds in the matrix determines texture artifacts introduced into the halftoned image. Thus, the challenge of research in ordered dithe...

In this paper we present a method to generate a digital mosaic starting from a raster input image. Mosaics generation of artistic quality is challenging. The basic elements, the tiles, typically small polygons, must be packed tightly, emphasizing orientations chosen by the artist. An ad­hoc boundaries detection have to be performed according to the directional g...

A novel approach to the creation of assemblages of three-dimensional digital objects is presented and explored. The proposed evolutionary art approach allows the evolution of the distribution of 3D objects, which are placed on a virtual canvas, constructing a non-photorealistic transformation of a source image. The approach is thoroughly described, giving particular emphasis to the interaction ...

From art portraits, the observer may derive at least two different hedonic values: The attractiveness of the depicted person and the artistic beauty of the image that relates to the way of presentation. We argue that attractiveness is a property that is predominantly driven by perceptual processes, while the perception of artistic beauty is based predominantly on cognitive processing. To test t...

This paper investigates the use of the Bayesian inference for devising an example-based rendering procedure. As prior model of this Bayesian inference, we exploit the multiscale non-parametric model recently proposed by Wei et al. for texture synthesis. This model appears to be interesting to also capture some characteristics of a rendering style from an artistic illustration example. Obtained ...

Image analogies is a framework for processing images by example. Image analogies uses training data A and A′ in order to learn a filter that can be applied to an unfiltered target image B to produce an analogous image B′. This means that B′ relates to B the same way A′ relates to A. The framework is general and can be applied to many different applications. Typical applications for image analog...

In a recent publication [Ostromoukhov95], a new image reproduction technique, Artistic Screening, was presented. It incorporates freely created artistic screen elements for generating halftones. Fixed predefined dot contours associated with given intensity levels determine the screen dot shape's growing behaviour. Screen dot contours associated with each intensity level are obtained by interpol...

From the strict mathematical viewpoint, it is impossible to fully achieve the goal of digital image processing, which ].sto determine an unknown function of two dimensions from a finite number of discrete measurements Linearly related to it. However, the necessity to display image data in a form that is visually useful to an observer s~persedee such mathematically correct admonitions. Engineeri...
