Source-Free Domain Adaptation of Weakly-Supervised Object Localization Models for Histology

1 code implementation29 Apr 2024 Alexis Guichemerre, Soufiane Belharbi, Tsiry Mayet, Shakeeb Murtaza, Pourya Shamsolmoali, Luke McCaffrey, Eric Granger

A WSOL model initially trained on some labeled source image data can be adapted using unlabeled target data in cases of significant domain shifts caused by variations in staining, scanners, and cancer type.

Realistic Model Selection for Weakly Supervised Object Localization

1 code implementation15 Apr 2024 Shakeeb Murtaza, Soufiane Belharbi, Marco Pedersoli, Eric Granger

Our experimental results with several WSOL methods on ILSVRC and CUB-200-2011 datasets show that our noisy boxes allow selecting models with performance close to those selected using ground truth boxes, and better than models selected using only image-class labels.

DiPS: Discriminative Pseudo-Label Sampling with Self-Supervised Transformers for Weakly Supervised Object Localization

1 code implementation9 Oct 2023 Shakeeb Murtaza, Soufiane Belharbi, Marco Pedersoli, Aydin Sarraf, Eric Granger

Subsequently, these proposals are used as pseudo-labels to train our new transformer-based WSOL model designed to perform classification and localization tasks.

CoLo-CAM: Class Activation Mapping for Object Co-Localization in Weakly-Labeled Unconstrained Videos

1 code implementation16 Mar 2023 Soufiane Belharbi, Shakeeb Murtaza, Marco Pedersoli, Ismail Ben Ayed, Luke McCaffrey, Eric Granger

This paper proposes a novel CAM method for WSVOL that exploits spatiotemporal information in activation maps during training without constraining an object's position.

Counterfactual Explanation and Instance-Generation using Cycle-Consistent Generative Adversarial Networks

1 code implementation21 Jan 2023 Tehseen Zia, Zeeshan Nisar, Shakeeb Murtaza

However, since it is often not straight forward to obtain the labels in many application domains such as in medical image, classification-based approaches have become the de facto standard to perform the diagnosis.

Constrained Sampling for Class-Agnostic Weakly Supervised Object Localization

no code implementations9 Sep 2022 Shakeeb Murtaza, Soufiane Belharbi, Marco Pedersoli, Aydin Sarraf, Eric Granger

Then, foreground and background pixels are sampled from these regions in order to train a WSOL model for generating activation maps that can accurately localize objects belonging to a specific class.
