Inferring Point Cloud Quality via Graph Similarity [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2020 Objective quality estimation of media content plays a vital role in a wide range of applications. Though numerous metrics exist for 2D images and videos, similar metrics are missing for 3D point clouds with unstructured and non-uniformly distributed ...

Building Geometry Simplification for Improving Mesh Quality of Numerical Analysis Model
Applied Sciences, 2020 Numerical analysis, especially the finite volume method (FVM), is one of the primary approaches employed when evaluating a building environment. A complicated geometry can degrade the mesh quality, leading to numerical diffusions and errors.

Detecting image differences based on reference EMD-filters [PDF]
Компьютерная оптика, 2018 In our previous works dealing with detecting differences in images in the case of substantial variations in brightness and geometry of an object, we proposed a morphological scheme for image analysis based on diffusion and reference mosaic filters.
