BrainPainter: A software for the visualisation of brain structures, biomarkers and associated pathological processes [PDF]
, 2019 We present BrainPainter, a software that automatically generates images of highlighted brain structures given a list of numbers corresponding to the output colours of each region. Compared to existing visualisation software (i.e.

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

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.

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

Cubic Bézier-Like Triangular Patches for Rainfall Scattered Data Interpolation and Visualization [PDF]
ITM Web of ConferencesScattered data interpolation plays an important role in computer graphics and scientific visualization. This method can be used to interpolate any regular or irregular data sets. For instance, rainfall distribution is an example of an irregular data that

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 ...

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
