About

I am a Computer Science researcher with an M.S. from Texas State University.

My research focuses on:

  • Neural Video Compression
  • Computer Vision
  • Edge AI
  • Multimedia Systems
  • Efficient Machine Learning

My master's research investigated ROI-aware video compression for resource-constrained wildlife monitoring systems, combining sparse animal detection, optical-flow tracking, motion-aware frame selection, and ROI/background compression.

I am also a co-author of an accepted IEEE ICTAI 2026 short paper on ROI-aware wildlife video compression and reconstruction.


Publication

FaunaCodec: ROI-Aware Video Compression and Reconstruction for Wildlife Monitoring

Mykhailo Sakevych, Felix Mathew, and Vangelis Metsis

Accepted short paper,
38th IEEE International Conference on Tools with Artificial Intelligence (ICTAI 2026)

The work investigates ROI-aware wildlife video compression across neural and conventional codec backends.


Research

Neural Region-of-Interest-Aware Video Compression for Wildlife Monitoring Under Edge Computing Constraints

M.S. Thesis · Texas State University · Advisor: Dr. Vangelis Metsis

Developed an ROI-aware video compression framework for resource-constrained wildlife monitoring systems using sparse animal detection, KLT optical-flow tracking, motion-aware frame selection, and separate ROI/background compression.

At the selected thesis operating point, the system achieved a 97.40% reduction in transmitted archive size across 20 held-out wildlife clips while prioritizing visual quality in animal regions.

Deterministic INT16 Runtime for DCVC-RT

Research Software · PyTorch · CUDA/C++ · INT16 · rANS · FFmpeg

Developed a deterministic INT16 runtime adaptation for a DCVC-RT-family neural video codec to support reproducible edge-to-server neural video compression workflows.

The project includes:

  • deterministic entropy-state handling
  • rANS entropy coding
  • encode/decode validation
  • SHA-256 verification
  • byte-level bitstream comparison
  • CUDA/C++ runtime integration

A same-environment validation produced identical SHA-256 hashes and byte-for-byte identical bitstreams across repeated runs.
