Deep Learning / Big Data Researcher
A DICOM-Embedded Annotation System for 3D Cross-Sectional Imaging Data

- Integrated a Python plugin for a medical image viewer app to translate between segmentation maps and tabular point-and-radius CSV data.  
- Using this to visualize ML predictions on CT scans (i.e. Lung Nodule Localization) and provide radiologists a highly efficient annotation system for producing training data.
- Presented a poster and open-source code demo at the Radiological Society of North America’s 2019 conference.

Deep Structure From Motion
May 11, 2018
Modified a state-of-the-art unsupervised learning framework for the task of monocular depth and camera motion estimation from unstructured video sequences. The baseline model uses fully convolutional neural networks to simultaneously train the estimation of motion relative to a rigid scene and the estimation of depth using the structure of a target scene. Rather than using ground truth for training, the baseline uses novel view synthesis as a supervisory signal.
Our modified approach attaches a Mask R-CNN to segment images into different objects. We incorporate an additional loss function promoting depth gradients around object segments to sharpen our depth maps around object boundaries. Empirical evaluation on the KITTI dataset indicates that our approach performs slightly better than the state-of-the-art.
