Method for registration of 3D shapes without overlap for known 3D priors
Electronics Letters, 2021 In 3D registration of point clouds, the goal is to find an optimal transformation that aligns the input shapes, provided that they have some overlap. Existing methods suffer from performance degradation when the overlapping ratio between the neighbouring

Extensible Implementation of Reliable Pixel Art Interpolation
Foundations of Computing and Decision Sciences, 2019 Pixel art is aesthetics that emulates the graphical style of old computer systems. Graphics created with this style needs to be scaled up for presentation on modern displays. The authors proposed two new modifications of image scaling for this purpose: a

Image Sampling with Quasicrystals [PDF]
, 2009 We investigate the use of quasicrystals in image sampling. Quasicrystals produce space-filling, non-periodic point sets that are uniformly discrete and relatively dense, thereby ensuring the sample sites are evenly spread out throughout the sampled image.

Soft bilateral filtering volumetric shadows using cube shadow maps.
PLoS ONE, 2017 Volumetric shadows often increase the realism of rendered scenes in computer graphics. Typical volumetric shadows techniques do not provide a smooth transition effect in real-time with conservation on crispness of boundaries. This research presents a new

Assessment criteria for 2D shape transformations in animation [PDF]
, 1997 The assessment of 2D shape transformations (or morphing) for animation is a difficult task because it is a multi-dimensional problem. Existing morphing techniques pay most attention to shape information interactive control and mathematical simplicity ...

Spatial and Angular Resolution Enhancement of Light Fields Using Convolutional Neural Networks [PDF]
, 2018 Light field imaging extends the traditional photography by capturing both spatial and angular distribution of light, which enables new capabilities, including post-capture refocusing, post-capture aperture control, and depth estimation from a single shot.

Conformal-Based Surface Morphing and Multi-Scale Representation
Axioms, 2014 This paper presents two algorithms, based on conformal geometry, for the multi-scale representations of geometric shapes and surface morphing. A multi-scale surface representation aims to describe a 3D shape at different levels of geometric detail, which

Deep Fluids: A Generative Network for Parameterized Fluid Simulations
, 2018 This paper presents a novel generative model to synthesize fluid simulations from a set of reduced parameters. A convolutional neural network is trained on a collection of discrete, parameterizable fluid simulation velocity fields.
