A Survey on Deep Learning for Skin Lesion Segmentation

1 code implementation1 Jun 2022 Zahra Mirikharaji, Kumar Abhishek, Alceu Bissoto, Catarina Barata, Sandra Avila, Eduardo Valle, M. Emre Celebi, Ghassan Hamarneh

We analyze these works along several dimensions, including input data (datasets, preprocessing, and synthetic data generation), model design (architecture, modules, and losses), and evaluation aspects (data annotation requirements and segmentation performance).

D-LEMA: Deep Learning Ensembles from Multiple Annotations -- Application to Skin Lesion Segmentation

no code implementations14 Dec 2020 Zahra Mirikharaji, Kumar Abhishek, Saeed Izadi, Ghassan Hamarneh

To this end, we propose an ensemble of Bayesian fully convolutional networks (FCNs) for the segmentation task by considering two major factors in the aggregation of multiple ground truth annotations: (1) handling contradictory annotations in the training data originating from inter-annotator disagreements and (2) improving confidence calibration through the fusion of base models' predictions.

WhiteNNer-Blind Image Denoising via Noise Whiteness Priors

no code implementations8 Aug 2019 Saeed Izadi, Zahra Mirikharaji, Mengliu Zhao, Ghassan Hamarneh

Specifically, by using total variation and piecewise constancy priors along with noise whiteness priors such as auto-correlation and stationary losses, our network learns to decouple an input noisy image into the underlying signal and noise components.
