Morphable guidelines are a 3D structure that helps users achieve better face warping on 2D portrait images. Faces can be difficult to warp accurately because the rotation of the head affects the shape of the facial features. I bypass the problem by utilizing the popular Loomis ‘ball and plane’ head drawing guideline as a proxy structure. The resulting ‘morphable guidelines’ consist of a simple 3D head model that can be reshaped by the user and aligned to their input image. The vertices of the model go on to act as deformation points for a 2D image deformation algorithm. Thus, the user can seamlessly transform the face proportions in the 2D image by transforming the proportions of the morphable guidelines. This system can be used for both retouching and caricature warping purposes, as it is well-suited for both subtle and extreme modifications. This system is advantageous over previous work in face warping because our morphable guidelines can be used on a wide range of head orientations and do not require the generation of a full 3D model. / Graduate / 0984 / syugao@gmail.com

Diploma thesis Mediatization as a consequence of self-presentation on social networks: publishing norms and their influence on Instagram users explores how Instagram and its affordances are able to change the behavior of its users, focusing on the aspect of photo sharing and related publishing norms. The aim of this work is to find out the practices which users do with photos and because of them before sharing them on Instagram, but above all it is about deeper understanding of the detected behavior and exploring whether and how such behavior interferes with users' lives. Within the theoretical part, the reader is acquainted with the development of the image, the origin of photography, its manipulations and changes in the digital era. Furthermore, the thesis presents visual social networks, the principles of Instagram operation and findings from current studies on the topic of self-presentation on social networks. In the last part, I deal specifically with Instagram photography, its types, methods of editing and sharing, based mainly on two current studies on this topic, the authors of which are Lev Manovich and Elisa Serafinelli. The second half of the thesis presents the research methodology, its design, results and final summary.
