Self-supervised Learning for Segmentation and Quantification of Dopamine Neurons in Parkinson's Disease

no code implementations11 Jan 2023 Fatemeh Haghighi, Soumitra Ghosh, Hai Ngu, Sarah Chu, Han Lin, Mohsen Hejrati, Baris Bingol, Somaye Hashemifar

To this end, we propose an end-to-end deep learning framework based on self-supervised learning for the segmentation and quantification of dopaminergic neurons in PD animal models.

DeepAD: A Robust Deep Learning Model of Alzheimer's Disease Progression for Real-World Clinical Applications

no code implementations17 Mar 2022 Somaye Hashemifar, Claudia Iriondo, Evan Casey, Mohsen Hejrati, for Alzheimer's Disease Neuroimaging Initiative

Our proposed model integrates high dimensional MRI features from a 3D convolutional neural network with other data modalities, including clinical and demographic information, to predict the future trajectory of patients.

Analysis by Synthesis: 3D Object Recognition by Object Reconstruction

no code implementations CVPR 2014 Mohsen Hejrati, Deva Ramanan

We introduce an efficient "brute-force" approach to inference that searches through a large number of candidate reconstructions, returning the optimal one.

Analyzing 3D Objects in Cluttered Images

no code implementations NeurIPS 2012 Mohsen Hejrati, Deva Ramanan

We use a morphable model to capture 3D within-class variation, and use a weak-perspective camera model to capture viewpoint.
