Anatomy of Deep Learning Image Classification and Object Detection on Commercial Edge Devices: A Case Study on Face Mask Detection
Kolosov, Dimitrios; Kelefouras, Vasilios; Kourtessis, Pandelis; Mporas, Iosif (2022-10-13)Developing efficient on-the-edge Deep Learning (DL) applications is a challenging and non-trivial task, as first different DL models need to be explored with different trade-offs between accuracy and complexity, second, ... -
Contactless Camera-Based Heart Rate and Respiratory Rate Monitoring Using AI on Hardware
Kolosov, Dimitrios; Kelefouras, Vasilios; Kourtessis, Pandelis; Mporas, Iosif (2023-05-07)Detecting vital signs by using a contactless camera-based approach can provide several advantages over traditional clinical methods, such as lower financial costs, reduced visit times, increased comfort, and enhanced safety ... -
A high-performance matrix–matrix multiplication methodology for CPU and GPU architectures
Mporas, Iosif; Kelefouras, Vasilios; Kritikakou, Angeliki; Kolonias, Vasilios (2016-03-01)Current compilers cannot generate code that can compete with hand-tuned code in efficiency, even for a simple kernel like matrix–matrix multiplication (MMM). A key step in program optimization is the estimation of optimal ... -
Illegal Logging Detection Based on Acoustic Surveillance of Forest
Mporas, Iosif; Perikos, Isidoros; Kelefouras, Vasilios; Paraskevas, Michael (2020-10-21)In this article, we present a framework for automatic detection of logging activity in forests using audio recordings. The framework was evaluated in terms of logging detection classification performance and various widely ...
