Medial Parametrization of Arbitrary Planar Compact Domains with Dipoles
Vinayak Krishnamurthy, Ergun Akleman
We present medial parametrization, a new approach to parameterizing any compact planar domain bounded by simple closed curves. The basic premise behind our proposed approach is to…
Development of Context-Sensitive Formulas to Obtain Constant Luminance Perception for a Foreground Object in Front of Backgrounds of Varying Luminance
Ergun Akleman, Bekir Tevfik Akgun, Adil Alpkocak
In this article, we present a framework for developing context-sensitive luminance correction formulas that can produce constant luminance perception for foreground objects. Our fo…
A Modified de Casteljau Subdivision that Supports Smooth Stitching with Hierarchically Organized Bicubic Bezier Patches
Saied Zarrinmehr, Ergun Akleman, Jianer Chen
One of the theoretically intriguing problems in computer-aided geometric modeling comes from the stitching of the tensor product Bezier patches. When they share an extraordinary ve…
Projective Holder-Minkowski Colors: A Generalized Set of Commutative & Associative Operations with Inverse Elements for Representing and Manipulating Colors
Ergun Akleman, Somyung, Oh +3
One of the key problems in dealing with color in rendering, shading, compositing, or image manipulation is that we do not have algebraic structures that support operations over col…
On The Power of Subtle Expressive Cues in the Perception of Human Affects
Ezgi Dede, Kamile Asli Agilonu, Ergun Akleman +1
In this study, we introduce a sketch-based method for testing how subtle expressive cues influence the perception of affect in illustrations of human figures. We specifically study…
Hyper-Realist Rendering: A Theoretical Framework
Ergun Akleman, Murat Kurt, Derya Akleman +3
This is the first paper in a series on hyper-realist rendering. In this paper, we introduce the concept of hyper-realist rendering and present a theoretical framework to obtain hyp…
Compositing with 2D Vector Fields by using Shape Maps that can represent Inconsistent, Impossible, and Incoherent Shapes
Ergun Akleman, Youyou Wang, Ozgur Gonen
In this paper, we present a new compositing approach to obtain stylized reflections and refractions with a simple control. Our approach does not require any mask or separate 3D ren…
Representing and Modeling Inconsistent, Impossible, and Incoherent Shapes and Scenes with 2D Non-Conservative Vector Fields mapped on 2-Complexes
Ergun Akleman, Youyou Wang, Ozgur Gonen
In this paper, we present a framework to represent mock 3D objects and scenes, which are not 3D but appear 3D. In our framework, each mock-3D object is represented using 2D non-con…
