SCorP: Statistics-Informed Dense Correspondence Prediction Directly from Unsegmented Medical Images

no code implementations27 Apr 2024 Krithika Iyer, Jadie Adams, Shireen Y. Elhabian

Traditional methods for shape modeling from imaging data demand significant manual and computational resources.

ADASSM: Adversarial Data Augmentation in Statistical Shape Models From Images

no code implementations6 Jul 2023 Mokshagna Sai Teja Karanam, Tushar Kataria, Krithika Iyer, Shireen Elhabian

However, these augmentation methods focus on shape augmentation, whereas deep learning models exhibit image-based texture bias resulting in sub-optimal models.

Mesh2SSM: From Surface Meshes to Statistical Shape Models of Anatomy

1 code implementation13 May 2023 Krithika Iyer, Shireen Elhabian

Statistical shape modeling is the computational process of discovering significant shape parameters from segmented anatomies captured by medical images (such as MRI and CT scans), which can fully describe subject-specific anatomy in the context of a population.

Statistical Shape Modeling of Biventricular Anatomy with Shared Boundaries

no code implementations6 Sep 2022 Krithika Iyer, Alan Morris, Brian Zenger, Karthik Karanth, Benjamin A Orkild, Oleksandre Korshak, Shireen Elhabian

This paper presents a general and flexible data-driven approach for building statistical shape models of multi-organ anatomies with shared boundaries that capture morphological and alignment changes of individual anatomies and their shared boundary surfaces throughout the population.

RENs: Relevance Encoding Networks

no code implementations25 May 2022 Krithika Iyer, Riddhish Bhalodia, Shireen Elhabian

With extensive experimentation on synthetic and public image datasets, we show that the proposed model learns the relevant latent bottleneck dimensionality without compromising the representation and generation quality of the samples.
