2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)

Year: 2024 | Conference Paper |

HTML

In medical imaging, leveraging continual learning (CL) is key for models to adapt to new classes and data distributions without forgetting prior knowledge. Existing CL methods often overlook the use of off-the-shelf pretrained models that are equipped with informative and generalizable representations, opting instead to learn from scratch. In this paper, we propose Continual-Zoo, a novel CL paradi...Show More

IEEE Transactions on Medical Imaging

Year: 2024 | Volume: 43, Issue: 11 | Journal Article |

HTML

Deep learning models have achieved remarkable success in medical image classification. These models are typically trained once on the available annotated images and thus lack the ability of continually learning new tasks (i.e., new classes or data distributions) due to the problem of catastrophic forgetting. Recently, there has been more interest in designing continual learning methods to learn di...Show More

2023 20th Conference on Robots and Vision (CRV)

Year: 2023 | Conference Paper |

Object counting methods rely on density maps, which are heatmaps produced by placing Gaussian density over object locations. However, density maps are expensive to collect. To reduce the annotation burden, we propose a form of weak supervision that only requires object-based pairwise image rankings. These annotations can be collected rapidly with a single click per image pair and supply a weak sig...Show More

Deep learning (DL) models trained to minimize empirical risk on a single domain often fail to generalize when applied to other domains. Model failures due to poor generalizability are quite common in practice and may prove quite perilous in mission-critical applications, e.g., diagnostic imaging where real-world data often exhibits pronounced variability. Such limitations have led to increased int...Show More

Diffuse optical tomography (DOT) leverages near-infrared light propagation through tissue to assess its optical properties and identify abnormalities. DOT image reconstruction is an ill-posed problem due to the highly scattered photons in the medium and the smaller number of measurements compared to the number of unknowns. Limited-angle DOT reduces probe complexity at the cost of increased reconst...Show More
