SCK: a Novel Key-point Detector
Professor Ling Guan
Director of The Ryerson Multimedia Research Laboratory
Tier I Canada Research Chair in Multimedia (2001-2015)
Department of Electrical and Computer Engineering
Ryerson University, Toronto, Canada
Abstract. Since David Lowe introduced SIFT (Scale-Invariant Feature Transform) in 2004, key-point detection and associated feature extraction have become a mainstream in extracting distinctive invariant features in images. However, all the key-point detectors documented in the literature are based on some kind of hand crafted structures such as blobs, corners, junctions, etc, restricting the search for optimal key- points and features to a subset of all the potential candidates. After an overview on state-of-the-art in key-point detectors, we introduce SCK, a universal key-point detector built upon the theory of sparse coding. SCK can handle any visual structures (blobs, corners, junctions, and more) and has been analytically proven to be invariant to changes in illumination, spatial and rotational transformations. Results show SCK outperforms all the hand-crafted detectors such as SIFT, Harris Corner, etc, and recent deep learning based detectors, setting a new standard for extracting high quality features for image analysis and visual communication.
WIDECOM 2020 Tutorials
Tutorial 1: A Gentle Introduction to Blockchain Technology
Dr. Sherif Saad Ahmed
Department of Computer Science
University of Windsor, Canada
Abstract. This tutorial is suitable for computer science, computer engineering, and software engineering students, researchers, and professionals. The objective of this tutorial is to give the students, researchers, and professionals a theoretical and practical introduction to blockchain and distributed ledger technology using a technology and platform-agnostic approach. We will not focus on specific blockchain platforms such as Hyperledger, Etherum or any other off-the-shelf platform. Instead, we will build a blockchain network from scratch using a vanilla approach and a simple python script. 
Tutorial 2: WLAN Defense – The pathway toward 5G security
Dr. Glaucio H. S. Carvalho
Professor of Computer Science and Information Security
School of Applied Computing
Sheridan College, Oakville Campus, Canada
Abstract. It has been anticipated that 5G will offload 71% of its traffic to WLAN by 2022. While this figure lays out the key role of Wi-Fi technologies within the roadmap of emerging 5G wireless networks, it also raises a red flag on the importance of actively guarding WLAN against attacks. In this tutorial, we will walk through WLAN encryption, authentication, and security infrastructure while setting up the enterprise security using network simulators and demonstrating attacks to WiFi systems using Kali Linux, a wireless card, and an Access Point. 
Note: This is a Bring Your Own Device (BYOD) tutorial. Please install in advance the Cisco Packet Tracer Simulator, which is available at:
Tutorial 3: Communication Requirements for autonomous and Electric Vehicles: Can Visible Light provide a viable Alternative?
Professor Xavier Fernando
Director of Ryerson Communications Lab
IEEE Communications Society Distinguished Lecturer
Department of Electrical and Computer Engineering
Ryerson University, Canada
Abstract. Autonomous Vehicles (AVs) are incredibly disruptive and can be referred as the third transportation revolution. AVs will not only save commuting time and labour but also alleviate the need for huge parking lots, taxi services or even public transport. When AVs use electricity for fueling, there will be a very positive impact on air pollutionin as well. However, there are still many technical hurdles to overcome before fully realizing the benefits of AVs. In addition to machine learning and multi-sensor information fusion, V2X communication (where, X stand for Vehicle, Infrastructure or Network) is very essential for many safety aspects of AVs. 5G network-based RF solutions promise ultra-reliable low-latency connections for AV user cases via network slicing. On another frontier, Visible Light Communications (VLC) is gaining momentum to provide short-rangeV2X connectivity. Wide deployment of solid-state lights and, image sensors in vehicles enable simultaneous lighting, sensing and communication possibilities. The talk will highlight state of the art research issues in real time communication solutions for vehicular networks.
