Abstract
Posters and advertisements are an essential part of the everyday life, and their creation is an important designer's task. Although there are attempts to fully automate the process, this thesis focuses on a task of recolouring poster elements so the final result looks harmonious and appealing. The main deliverable is the colouring application which should help designers to find optimal harmonious colour schemes for advertisement posters and user interfaces. While existing recolouring methods focus on the whole image, the one proposed in this study treats each of the poster components (e.g., title or background) separately. The recolouring is completed in four steps, and it aims to complement the key vision, not to change it. At first, the most prominent colours are extracted from the product image. After that the basic palette is expanded by one colour which is found computationally. Next, these colours are assigned to the poster components. As a final step, the original colours of these components are mixed with the newly assigned ones, and the output is rendered. The basic pipeline is flexible and can be tailored to the user needs, so the control remains in the designer's hands. The colouring algorithm can be used as either the CLI or the GUI application.
