Edge-preserving smoothing filters for improving object classification

Author: Skosana, Vusi J ; Kunene, Dumisani C Date: Sep 2019 Edge-preserving smoothing filters have had many applications in the image processing community, such as image compression, restoration, deblurring and abstraction. However, their potential application in computer vision and machine learning ... Read more
The effects of image smoothing on CNN-based detectors

Author: Skosana, Vusi J ; Ngxande, M Date: Jan 2020 Edge-preserving smoothing filters have been shown to improve generalisation performance on the HOG features with a SVM classifier. However, not all smoothing filters and parameters lead to better performance. The effects of smoothing filters ... Read more
Energy-efficient sensing matrices for Wireless Multimedia Sensor Networks: A Review

Author: Skosana, Vusi J ; Abu-Mahfouz, Adnan MI Date: Dec 2021 Wireless Multimedia Sensor Networks (WMSN) hold the key to unlocking the next generation of video surveillance applications. They operate under energy-constrained environments but Compressive Sensing (CS) is a tool that can help overcome these ... Read more
An energy-efficient sensing matrix for wireless multimedia sensor networks

Author: Skosana, Vusi J ; Abu-Mahfouz, Adnan MI Date: May 2023 A measurement matrix is essential to compressed sensing frameworks. The measurement matrix can establish the fidelity of a compressed signal, reduce the sampling rate demand, and enhance the stability and performance of the recovery algorithm. ... Read more
Enhancing edge-based image descriptor models through colour unification

Author: Kunene, Dumisani ; Skosana, Vusi J Date: Jan 2019 The lack of suitable robust appearance models hinders the performance of most image descriptors. Descriptors often rely on pieces of information in images called image features to discriminate the contents of images. Most successful descriptors ... Read more
Image quality assessment methods for near-infrared wildfire imagery

Author: Faniso-Mnyaka, Zimbini ; Skosana, Vusi J ; Nana, Muhammad A ; Magidimisha, Edwin Date: Oct 2022 Over the past two decades, there has been a surge of interest in the study of image quality assessment due to its broad applicability in many fields. Satellites and other remote sensing applications have been collecting vital data that is ... Read more
Performance comparison of video encoding at low sampling rates

Author: Skosana, Vusi J ; Abu-Mahfouz, Adnan MI Date: Nov 2021 Video encoding is challenging in the energy-constrained environments Wireless Multimedia Sensor Networks (WMSN) operate. Among the many design considerations when developing a video encoding scheme, the first is the sparsity transform, however, ... Read more
A UAV based system for real-time near-infrared monitoring of small-scale wildfires

Author: Magidimisha, Edwin ; Nana, Muhammad A ; Naidoo, Seelenthren ; Naidoo, Shrikant V ; Faniso-Mnyaka, Zimbini ; Skosana, Vusi J Date: 2023 Wildfires are a global threat that is becoming more severe and widespread due to climate change. These fires not only pose a significant risk to human life, firefighters, and infrastructure, but also endanger forest resources, increase ... Read more
Video encoding for wireless multimedia sensor networks: A review

Author: Skosana, Vusi J ; Abu-Mahfouz, Adnan MI Date: Nov 2020 Wireless multimedia sensor networks (WMSNs) make possible diverse and demanding monitoring and surveillance applications. The WMSNs have to operate with significant energy, memory and processing power constraints. These constraints make video ... Read more
