Crowd counting Proof of concept (Field deployment)
A snapshot of our crowd counting POC deployed in metro station using two PTZ cameras and a single NVIDIA's Jetson Nano, device, providing real-time counting.
Haris: Stereo-vision based Depth and Size estimation
Haris - The autonomous robot uses stereo-vision based object detection to estimate depth and size dimensions of the object from YOLO bounding boxes to avoid obstacles. This overcomes the limitations of LiDAR based sensing for non-reflective objects such as fire, smoke, etc and detect objects like sign boards. This is the Master thesis work of Layth Hamad .

Lightweight deep learning models
We developed efficient and lightweight model "LCDnet" for crowd density estimation and counting suitable for real-time performance in drones. The performance is validated on NVIDIA's Jetson Nano, and Jetson Xavior devices.
Curriculum learning: Train faster with high accuracy
Curriculum learning (CL) can improve learning and speed up convergence. Want to further reduce the training time of a model? We proposed "CLIP" to reduce training time using CL and dataset pruning.

Unauthorized Drone Detection: Survey
Drones can be a threat critical assets, infrastructure, ane privacy of people. A drone detection system shall be efficient, accurate, robust, cost-effective, and scalable. Read our comprehensive review article in IEEE Sensors journal.
Unauthorized Drone Detection: Experiments
We conducted experiment analysis on drone detection methods (i.e., acoustic detection, radio frequency (RF) detection, and visual detection) and our novel encryption-based scheme to detect unauthorized drones in the air. For acoustic detection, we used a ReSpeaker 4-mic array and RaspberryPi processor with Open EmbeddeD Audition System (ODAS) GUI. For RF detection, we used E312 USRP (by Ettusresearchâ˘) with a 2x2 MIMO transceiver. For visual detection, we used a PTZ camera WizSense series (model# SD6CE445XA-HNR) , and Jetson Xavier device.
CODE for IoT
Mobile edge computing (MEC) is promising a lot for 6G and IoT. How efficient edge computing can be? What if the edge resources are insufficient (have you ever heard of "thundering herd problem"?)! We propose a solution CODE to alleviate edge congestion in the event of unplanned traffic spikes.
Distributed Inference in IoT
Video processing using deep learning on the IoT device can be resource consuming, transmitting these can be bandwidth intensive. Distributed inference on local device and edge server can be good if delay deadlines are gauranteed. But how to split the model? An interesting article on distributed inference in Video IoT!

ML for Self-Organization Networks (SONs)
Machine learning can play a vital role in building cognitive network architectures that are self-organizing paving way towards zero-touch networks. To enhance end-user experience, transmission throughput is an important metric that has a strong impact on the end-user quality of experience. Our paper provides how to accurately estimate throughput in real-time.
Handover prediction in Wi-Fi
Throughput estimation can be useful but there are other challenges. We proposed ML schemes for prediction of network states (e.g. handover prediction) and efficient decision making (e.g. selection of access point).
Enhanced group formation for Wi-Fi Direct
Wi-Fi Direct, a technology by Wi-Fi Alliance allows Wi-Fi devices to connect to each other without access point (AP). We proposed a vital improvement to the specification that enables optimal dense network for content distribution. Read our work on Enhanced Group Formation in Wi-Fi Direct.
