Publications

Localized Questions in Medical Visual Question Answering

MICCAI 2023
Vancouver, Canada

We introduce a method to answer questions about user-defined regions in an image as opposed to questions about the entire image.

Logical Implications for Visual Question Answering Consistency

CVPR 2023
Vancouver, Canada

A method to improve consistency in VQA by integrating logical relations between pairs of question-answers into the tratining process.

Consistency-Preserving Visual Question Answering in Medical Imaging

MICCAI 2022
Singapore

This approach uses a regularizer to improve consistency in VQA for medical images. The idea is to penalize inconsistent cases during training.

Multiple Sclerosis Lesion Segmentation Using Longitudinal Normalization and Convolutional Recurrent Neural Networks

MLCN Workshop, MICCAI 2020
Lima, Perú (Virtual)

Longitudinal annotations are leveraged to improve segmentations of MS lesions. This is achieved with a combination of UNets and convolutional LSTMs.
