Enhanced Multi-Target Tracking in Dynamic Environments: Distributed Control Methods Within the Random Finite Set Framework

no code implementations25 Jan 2024 Aidan Blair, Amirali Khodadadian Gostar, Alireza Bab-Hadiashar, XiaoDong Li, Reza Hoseinnezhad

Tracking multiple targets in dynamic environments using distributed sensor networks is a challenging problem that has received significant attention in recent years.

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.

Anomaly Detection of Defect using Energy of Point Pattern Features within Random Finite Set Framework

1 code implementation27 Aug 2021 Ammar Mansoor Kamoona, Amirali Khodadadian Gostar, Alireza Bab-Hadiashar, Reza Hoseinnezhad

Experimental results show the outstanding performance of our proposed approach compared to the state-of-the-art methods, and the proposed RFS energy outperforms the state-of-the-art in the few shot learning settings.

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.

Evaluation of Point Pattern Features for Anomaly Detection of Defect within Random Finite Set Framework

no code implementations3 Feb 2021 Ammar Mansoor Kamoona, Amirali Khodadadian Gostar, Alireza Bab-Hadiashar, Reza Hoseinnezhad

The results show that using point pattern features, such as SIFT as data points for random finite set-based anomaly detection achieves the most consistent defect detection accuracy on the MVTec-AD dataset.

Multiple Instance-Based Video Anomaly Detection using Deep Temporal Encoding-Decoding

1 code implementation3 Jul 2020 Ammar Mansoor Kamoona, Amirali Khodadadian Gosta, Alireza Bab-Hadiashar, Reza Hoseinnezhad

The proposed approach uses both abnormal and normal video clips during the training phase which is developed in the multiple instance framework where we treat video as a bag and video clips as instances in the bag.
