Speaker: Prof. Amal Dev Parakkat (LTCI-Telecom Paris)
Abstract
In this talk, I will present different frameworks we developed using the geometric properties of Delaunay triangulation to process hand-drawn sketches. The presentation will focus on two key areas: sketch simplification (cleaning up rough sketches) and line art colorization (adding color to hand-drawn sketches, even those with gaps). I will demonstrate how our methods combine Delaunay triangulation with interactive user input to create powerful tools for enhancing hand-drawn sketches bridging the gap between initial rough concepts and refined digital representations. By the end of the presentation, you'll understand how our simple sketch-processing techniques can significantly benefit artists, designers, and digital content creators.
Bio
Amal Dev Parakkat has been working as a tenured Assistant Professor (Maitre de Conferences in French) at LTCI-Telecom Paris, Institut Polytechnique de Paris, since September 2021. Parakkat was born in Kerala, India. He is interested in practical algorithms for digital content creation tasks with the main focus on Sketch-based interfaces. He also works on fundamental problems in digital geometry processing, including reconstruction and meshing. He leads the ANR SketchMAD project on novel algorithms for sketch-based modeling (2024–2028) and heads the IGD masters at the Institut Polytechnique de Paris. He received the SMI Young Investigators Award 2024 and regularly serves on program committees of Eurographics, Pacific Graphics, Shape Modeling International, and Computer Graphics International. He will be the technical paper chair of Expressive 2025.
