Automatic Synthesis of Realistic Facial Expressions
2007 IEEE International Symposium on Signal Processing and Information Technology, 2007Facial expressions exhibit not only facial feature motions, but also subtle changes in illumination and appearance. Since it is difficult to generate realistic facial expressions by using only geometric deformations, the details such as textures should also be deformed to achieve expression that is more realistic.

A Quasi-realist Synthesis Investigating Professional Breastfeeding Support Failure
Research and Theory for Nursing Practice, 2022Background/Purpose:To conduct a synthesis based on a realist perspective, investigating how professional breastfeeding support can sometimes be ineffective and/or unsatisfactory from the viewpoint of the mother and fail to address the needs of the breastfeeding dyad.Methods:An innovative, targeted “quasi-realist” synthesis technique was used to ...

PERIS: A programming environment for realistic image synthesis
Computers & Graphics, 1988Abstract A computer graphics system called PERIS is described. It offers two levels of user interfaces to serve both as a testbed to facilitate further research work and as a pragmatic system for CAD/CAM applications. Flexibility of the system is achieved by providing tools of solid modeling, surface modeling and procedural model representations for ...

Realistic image synthesis with hybrid photon maps
Optoelectronic Imaging and Multimedia Technology VII, 2020In the scope of the current research, authors have developed an approach to accelerate the synthesis of realistic images with bidirectional ray tracing based on the consecutive usage of the photon maps and backward photon (imphoton) maps. In the presented approach the photon maps are used to account for the possible sources of caustic illumination ...

Shading models for realistic image synthesis
Proceedings of the IEEE National Aerospace and Electronics Conference, 2003A tutorial that presents a technical-level chronology of illumination model development is provided. The basic techniques and capabilities of certain algorithms that changed the direction of computer graphics research are described. Included are treatments of Lambertian (constant) shading, Gouraud shading, Phong shading, the Torrence-Sparrow ...

The Synthesis of Realistic Human Face
2000In this paper, we present new techniques for creating a realistic specific human face based on a general 3D face model and several photos of a human. The morphing technique allows interactive alignment of features of the general geometric face model with the features of the multi-direction images of the specific human face, which are pre-provided by ...

Dealing With Complex Causality in Realist Synthesis
American Journal of Evaluation, 2011In this article, the authors state two arguments: first, that the four categories of context, politics, polity, and policy make an adequate framework for systematic review being both exhaustive and parsimonious; second, that the method of qualitative comparative analysis (QCA) is an appropriate methodical approach for gaining realistic results that ...

Modeling pigmented materials for realistic image synthesis
ACM Transactions on Graphics, 1992This article discusses and applies the Kubelka-Munk theory of pigment mixing to computer graphics in order to facilitate improved image synthesis. The theories of additive and subtractive color mixing are discussed and are shown to be insufficient for pigmented materials. The Kubelka–Munk theory of pigment mixing is developed and the relevant equations

Depth Texture Synthesis for Realistic Architectural Modeling
2016 13th Conference on Computer and Robot Vision (CRV), 2016Large scenes such as building facades and other architectural constructions often contain repeating elements like identical windows, brick patterns, etc. In this paper, we present a novel approach that improves the resolution and geometry of 3D meshes of large scenes with such repeating elements.
