3D Tooth Mesh Segmentation with Simplified Mesh Cell Representation

1 code implementation25 Jan 2023 Ananya Jana, Hrebesh Molly Subhash, Dimitris N. Metaxas

Summarizing of the mesh cell/triangle in this manner imposes an implicit structural constraint and makes it difficult to work with multiple resolutions which is done in many point cloud based deep learning algorithms.

Automatic Tooth Segmentation from 3D Dental Model using Deep Learning: A Quantitative Analysis of what can be learnt from a Single 3D Dental Model

1 code implementation16 Sep 2022 Ananya Jana, Hrebesh Molly Subhash, Dimitris Metaxas

We conclude that the segmentation methods can learn a great deal of information from a single 3D tooth point cloud scan under suitable conditions e. g. data augmentation.

Liver Fibrosis and NAS scoring from CT images using self-supervised learning and texture encoding

1 code implementation5 Mar 2021 Ananya Jana, Hui Qu, Carlos D. Minacapelli, Carolyn Catalano, Vinod Rustgi, Dimitris Metaxas

The severity and treatment of NAFLD is determined by NAFLD Activity Scores (NAS)and liver fibrosis stage, which are usually obtained from liver biopsy.

Self-Supervised Learning Transfer Learning

Deep Learning based NAS Score and Fibrosis Stage Prediction from CT and Pathology Data

1 code implementation22 Sep 2020 Ananya Jana, Hui Qu, Puru Rattan, Carlos D. Minacapelli, Vinod Rustgi, Dimitris Metaxas

In this work, we propose a novel method to automatically predict NAS score and fibrosis stage from CT data that is non-invasive and inexpensive to obtain compared with liver biopsy.
