CS Researcher in SALA Art Exhibition
Aneta Neumann, a researcher from the School of Computer Science is exhibiting two mixed media artworks in Hub Central. The artworks are inspired by images produced by new methods in evolutionary image transition, pioneered by Aneta in her research toward her PhD.This research carried out within the Optimisation and Logistic Research Group in the School explores the fundamental link between evolutionary processes and generative art. The images will be on display in the Hub until the 18th of August. http://blogs.adelaide.edu.au/cs/2017/08/15/cs-researcher-in-sala-art-exhibition/

Evolutionary Image Composition Using Feature Covariance Matrices
Authors: Aneta Neumann, Zygmunt L Szpak, Wojciech Chojnacki, Frank Neumann
ABSTRACT: Evolutionary algorithms have recently been used to create a wide range of artistic work. In this paper, we propose a new approach for the composition of new images from existing ones, that retain some salient features of the original images. We introduce evolutionary algorithms that create new images based on a fitness function that incorporates feature covariance matrices associated with different parts of the images. This approach is very flexible in that it can work with a wide range of features and enables targeting specific regions in the images. For the creation of the new images, we propose a population-based evolutionary algorithm with mutation and crossover operators based on random walks. Our experimental results reveal a spectrum of aesthetically pleasing images that can be obtained with the aid of our evolutionary process.
Evolution of Artistic Image Variants Through Feature Based Diversity Optimisation
Authors: Bradley Alexander, James Kortman, Aneta Neumann
ABSTRACT: Measures aimed to improve the diversity of images and image features in evolutionary art help to direct search toward more novel and creative parts of the artistic search domain. To date such measures have focused on relatively indirect means of ensuring diversity in the context of search to maximise an aesthetic or similarity metric. In recent work on TSP problem instance classification, selection based on a direct measure of each individual's contribution to diversity was successfully used to generate hard and easy TSP instances. In this work we use an analogous search framework to evolve diverse variants of a source image in one and two feature dimensions. The resulting images show the spectrum of effects from transforming images to score across the range of each feature. The evolutionary process also reveals interesting correlations between feature values in both one and two dimensions.
Multi-objectiveness in the Single-objective Traveling Thief Problem
Authors: Mohamed El Yafrani, Shelvin Chand, Aneta Neumann, Belaid Ahiod, Markus Wagner
ABSTRACT: Multi-component problems are optimization problems that are composed of multiple interacting sub-problems. The motivation of this work is to investigate whether it can be better to consider multiple objectives when dealing with multiple interdependent components. Therefore, the Travelling Thief Problem, a relatively new benchmark problem, is investigated as a bi-objective problem. An NSGA-II adaptation for the bi-objective model is compared to three of the best known algorithms for the original single-objective problem. The results show that our approach generates diverse sets of solutions, while being competitive with the state-of-the-art single-objective algorithms.
Evolutionary Image Transition Using Random Walks
Authors: Aneta Neumann, Bradley Alexander, Frank Neumann
ABSTRACT: We present a study demonstrating how random walk algorithms can be used for evolutionary image transition. We design different mutation operators based on uniform and biased random walks and study how their combination with a baseline mutation operator can lead to interesting image transition processes in terms of visual effects and artistic features. Using feature-based analysis we investigate the evolutionary image transition behaviour with respect to different features and evaluate the images constructed during the image transition process.
A Modified Indicator-based Evolutionary Algorithm (mIBEA)
Authors: Li,W, Ozcan,E, John,R, Drake,JH, Neumann,A, Wagner,M, 2017
ABSTRACT: Multi-objective evolutionary algorithms (MOEAs) based on the concept of Pareto-dominance have been successfully applied to many real-world optimisation problems. Recently, research interest has shifted towards indicator-based methods to guide the search process towards a good set of trade-off solutions. One commonly used approach of this nature is the indicator-based evolutionary algorithm (IBEA). In this study, we highlight the solution distribution issues within IBEA and propose a modification of the original approach by embedding an additional Pareto-dominance based component for selection. The improved performance of the proposed modified IBEA (mIBEA) is empirically demonstrated on the well-known DTLZ set of benchmark functions. Our results show that mIBEA achieves comparable or better hypervolume indicator values and epsilon approximation values in the vast majority of our cases (13 out of 14 under the same default settings) on DTLZ1-7. The modification also results in an over 8-fold speed-up for larger populations.
The Evolutionary Process of Image Transition in Conjunction with Box and Strip Mutation
Authors: Aneta Neumann, Bradley Alexander, Frank Neumann
ABSTRACT: Evolutionary algorithms have been used in many ways to generate digital art.We study how the evolutionary processes can be used for evolutionary art and present a new approach to the transition of images. Our main idea is to define evolutionary processes for digital image transition, combining different variants of mutation and evolutionary mechanisms. We introduce box and strip mutation operators which are specifically designed for image transition. Our experimental results show that the process of an evolutionary algorithm in combination with these mutation operators can be used as a valuable way to produce unique generative art.
Evolutionary Image Transition Based on Theoretical Insights of Random Processes [ download ]
Authors: Aneta Neumann, Bradley Alexander, Frank Neumann
ABSTRACT: Evolutionary algorithms have been widely studied from a theoretical perspective. In particular, the area of runtime analysis has contributed significantly to a theoretical understanding and provided insights into the working behaviour of these algorithms. We study how these insights into evolutionary processes can be used for evolutionary art. We introduce the notion of evolutionary image transition which transfers a given starting image into a target image through an evolutionary process. Combining standard mutation effects known from the optimization of the classical benchmark function OneMax and different variants of random walks, we present ways of performing evolutionary image transition with different artistic effects.
