    • 2D Points Curve Reconstruction Survey and Benchmark 

      Ohrhallinger, Stefan; Peethambaran, Jiju; Parakkat, Amal Dev; Dey, Tamal Krishna; Muthuganapathy, Ramanathan (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Curve reconstruction from unstructured points in a plane is a fundamental problem with many applications that has generated research interest for decades. Involved aspects like handling open, sharp, multiple and non-manifold ...
    • 2D Points Curve Reconstruction Survey and Benchmark 

      Ohrhallinger, Stefan; Peethambaran, Jiju; Parakkat, Amal Dev; Dey, Tamal K.; Muthuganapathy, R. (The Eurographics Association, 2022)
      Curve reconstruction from unstructured points in a plane is a fundamental problem with many applications that has generated research interest for decades. Involved aspects like handling open, sharp, multiple and non-manifold ...
    • BallMerge: High-quality Fast Surface Reconstruction via Voronoi Balls 

      Parakkat, Amal Dev; Ohrhallinger, Stefan; Eisemann, Elmar; Memari, Pooran (The Eurographics Association and John Wiley & Sons Ltd., 2024)
      We introduce a Delaunay-based algorithm for reconstructing the underlying surface of a given set of unstructured points in 3D. The implementation is very simple, and it is designed to work in a parameter-free manner. The ...
    • Collision Free Simplification for 2D Multi-Layered Shapes 

      Gong, Xianjin; Parakkat, Amal Dev; Rohmer, Damien (The Eurographics Association, 2023)
      We propose a simplification-aware untangling algorithm for 2D layered shapes stacked on each other. While the shape undergoes simplification, our approach adjusts the vertex positions to prevent collision with other layers ...
    • Delaunay Painting: Perceptual Image Colouring from Raster Contours with Gaps 

      Parakkat, Amal Dev; Memari, Pooran; Cani, Marie‐Paule (© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2022)
      We introduce Delaunay Painting, a novel and easy‐to‐use method to flat‐colour contour‐sketches with gaps. Starting from a Delaunay triangulation of the input contours, triangles are iteratively filled with the appropriate ...
    • Driller: An Intuitive Interface for Designing Tangled and Nested Shapes 

      Butler, Tara; Guehl, Pascal; Parakkat, Amal Dev; Cani, Marie-Paule (The Eurographics Association, 2024)
      The ability to represent not only isolated shapes but also shapes that interact is essential in various fields, from design to biology or anatomy. In this paper, we propose an intuitive interface to control and edit complex ...
    • Feature-Sized Sampling for Vector Line Art 

      Ohrhallinger, Stefan; Parakkat, Amal Dev; Memari, Pooran (The Eurographics Association, 2023)
      By introducing a first-of-its-kind quantifiable sampling algorithm based on feature size, we present a fresh perspective on the practical aspects of planar curve sampling. Following the footsteps of e-sampling, which was ...
    • Interactive Depixelization of Pixel Art through Spring Simulation 

      Matusovic, Marko; Parakkat, Amal Dev; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      We introduce an approach for converting pixel art into high-quality vector images. While much progress has been made on automatic conversion, there is an inherent ambiguity in pixel art, which can lead to a mismatch with ...
    • Interactive Flat Coloring of Minimalist Neat Sketches 

      Parakkat, Amal Dev; Madipally, Prudhviraj; Gowtham, Hari Hara; Cani, Marie-Paule (The Eurographics Association, 2020)
      We introduce a simple Delaunay-triangulation based algorithm for the interactive coloring of neat line-art minimalist sketches, ie. vector sketches that may include open contours. The main objective is to minimize user ...
    • PointCloudSlicer: Gesture-based Segmentation of Point Clouds 

      Gowtham, Hari Hara; Parakkat, Amal Dev; Cani, Marie-Paule (The Eurographics Association, 2023)
      Segmentation is a fundamental problem in point-cloud processing, addressing points classification into consistent regions, the criteria for consistency being based on the application. In this paper, we introduce a simple, ...
    • Structuring and Layering Contour Drawings of Organic Shapes 

      Entem, Even; Parakkat, Amal Dev; Cani, Marie-Paule; Barthe, Loïc (ACM, 2018)
      Complex vector drawings serve as convenient and expressive visual representations, but they remain difficult to edit or manipulate. For clean-line vector drawings of smooth organic shapes, we describe a method to automatically ...
