I designed a hybrid system that combines Eulerian Video Magnification (EVM), 3D CNNs, and Transformer architectures to estimate pulse rates from facial videos. By amplifying subtle skin color variations and modeling long-range temporal dependencies, this method achieved a mean absolute error (MAE) of 12.47 bpm-outperforming existing approaches on Indian datasets. This work is part of a broader push to build inclusive, non-contact health monitoring tools tailored to real-world populations. https://aryanshirke.me/articles/jam-guardian https://aryanshirke.me/articles/jam-guardian Tue, 20 Jun 2023 00:00:00 GMT This research tackles signal degradation in adversarial environments, particularly under jamming attacks in wireless networks. JamGuardian introduces a robust recovery framework that combines intelligent error correction, jamming detection, and secure data transmission strategies like Dirty Paper Coding. By emulating jamming scenarios in a 6-node wireless testbed, the system identifies and neutralizes interference, optimizing communication efficiency in high-noise and attack-prone environments.
