Density-Based 3D Shape Descriptors [PDF]
EURASIP Journal on Advances in Signal Processing, 2007 We propose a novel probabilistic framework for the extraction of density-based 3D shape descriptors using kernel density estimation. Our descriptors are derived from the probability density functions (pdf) of local surface features characterizing the 3D ...

CellMet: Extracting 3D shape and topology metrics from confluent cells within tissues. [PDF]
PLoS Computational BiologyDuring development and tissue repair, cells reshape and reconfigure to ensure organs take specific shapes. This process is inherently three-dimensional (3D). Yet, in part due to limitations in imaging and data analysis, cell shape analysis within tissues

CAD models clustering with machine learning [PDF]
Archive of Mechanical Engineering, 2019 Similarity assessment between 3D models is an important problem in many fields including medicine, biology and industry. As there is no direct method to compare 3D geometries, different model representations (shape signatures) are developed to enable ...

Effects of Microstimulation in the Anterior Intraparietal Area during Three-Dimensional Shape Categorization. [PDF]
PLoS ONE, 2015 The anterior intraparietal area (AIP) of rhesus monkeys is part of the dorsal visual stream and contains neurons whose visual response properties are commensurate with a role in three-dimensional (3D) shape perception.
