Domain Generalization by Learning from Privileged Medical Imaging Information

no code implementations10 Nov 2023 Steven Korevaar, Ruwan Tennakoon, Ricky O'Brien, Dwarikanath Mahapatra, Alireza Bab-Hadiasha

This paper demonstrates that by using privileged information to predict the severity of intra-layer retinal fluid in optical coherence tomography scans, the classification accuracy of a deep learning model operating on out-of-distribution data improves from $0. 911$ to $0. 934$.

Domain Generalization

Single Domain Generalization via Normalised Cross-correlation Based Convolutions

no code implementations12 Jul 2023 WeiQin Chuah, Ruwan Tennakoon, Reza Hoseinnezhad, David Suter, Alireza Bab-Hadiashar

This approach is invariant to both affine shifts and changes in energy within a local feature patch and eliminates the need for commonly used non-linear activation functions.

Maximum Consensus by Weighted Influences of Monotone Boolean Functions

no code implementations CVPR 2022 Erchuan Zhang, David Suter, Ruwan Tennakoon, Tat-Jun Chin, Alireza Bab-Hadiashar, Giang Truong, Syed Zulqarnain Gilani

In particular, we study endowing the Boolean cube with the Bernoulli measure and performing biased (as opposed to uniform) sampling.

Robust Pooling through the Data Mode

no code implementations21 Jun 2021 Ayman Mukhaimar, Ruwan Tennakoon, Chow Yin Lai, Reza Hoseinnezhad, AlirezaBab-Hadiashar

The proposed pooling layer looks for data a mode/cluster using two methods, RANSAC, and histogram, as clusters are indicative of models.

Achieving Domain Robustness in Stereo Matching Networks by Removing Shortcut Learning

no code implementations15 Jun 2021 WeiQin Chuah, Ruwan Tennakoon, Alireza Bab-Hadiashar, David Suter

We provide evidence that demonstrates that learning of features in the synthetic domain by a stereo matching network is heavily influenced by two "shortcuts" presented in the synthetic data: (1) identical local statistics (RGB colour features) between matching pixels in the synthetic stereo images and (2) lack of realism in synthetic textures on 3D objects simulated in game engines.

Consensus Maximisation Using Influences of Monotone Boolean Functions

1 code implementation CVPR 2021 Ruwan Tennakoon, David Suter, Erchuan Zhang, Tat-Jun Chin, Alireza Bab-Hadiashar

Consensus maximisation (MaxCon), which is widely used for robust fitting in computer vision, aims to find the largest subset of data that fits the model within some tolerance level.

Rotation Averaging with Attention Graph Neural Networks

no code implementations14 Oct 2020 Joshua Thorpe, Ruwan Tennakoon, Alireza Bab-Hadiashar

In this paper we propose a single-stage graph neural network that can robustly perform rotation averaging in the presence of noise and outliers.

Outlier Detection

Adjusting Bias in Long Range Stereo Matching: A semantics guided approach

no code implementations10 Sep 2020 WeiQin Chuah, Ruwan Tennakoon, Reza Hoseinnezhad, Alireza Bab-Hadiashar, David Suter

Consequently, the learning algorithms often produce unreliable depth estimates of foreground objects, particularly at large distances~($>50$m).

Monotone Boolean Functions, Feasibility/Infeasibility, LP-type problems and MaxCon

no code implementations11 May 2020 David Suter, Ruwan Tennakoon, Erchuan Zhang, Tat-Jun Chin, Alireza Bab-Hadiashar

This paper outlines connections between Monotone Boolean Functions, LP-Type problems and the Maximum Consensus Problem.

Effective Sampling: Fast Segmentation Using Robust Geometric Model Fitting

1 code implementation26 May 2017 Ruwan Tennakoon, Alireza Sadri, Reza Hoseinnezhad, Alireza Bab-Hadiashar

In this paper, we propose an effective sampling method to obtain a highly accurate approximation of the full graph required to solve multi-structural model fitting problems in computer vision.
