Engineering & Research Systems
Complete index of machine learning architectures, spatial perception pipelines, multimodal agents, and high-throughput systems.
Autonomous Vessel Tracking & Visual Re-Identification System
Production maritime perception pipeline integrating YOLO vessel detection, OC-SORT tracking, and LoFTR + DINOv2 feature descriptors deployed on live RTSP streams via FastAPI.
Real-time vessel tracking on live maritime RTSP video feeds suffers from false-positive track fragmentation, wake interference, wave backscatter, and severe visual appearance changes as vessels change bearing.
PTZ Camera + LiDAR Multi-Domain Sensor Fusion Node
Spatial perception and tracking architecture integrating 3D LiDAR point clouds with PTZ optical cameras via ROS 2 and Extended Kalman Filtering.
Optical PTZ cameras provide detailed semantic classification but lack direct metric depth, while LiDAR point clouds offer accurate range but lack dense semantic labels; calibrating moving PTZ optical axes with LiDAR presents spatial-temporal synchronization challenges.
MedBot: AI Medical Knowledge Assistant & RAG Pipeline
Grounded retrieval-augmented generation pipeline indexing medical documents in Pinecone vector database with LangChain orchestration, OpenRouter, and FastAPI.
Medical Q&A systems require strictly factual, grounded information retrieval from complex medical literature; naive language models hallucinate terminology, dosages, and clinical guidelines without verifiable passage grounding.
Dual-EMA Real-Time Perimeter Intrusion Detection Pipeline
Classical computer vision perimeter security pipeline utilizing dual-EMA background subtraction, contour tracking, and global lighting change suppression on live CCTV feeds.
Perimeter security CCTV feeds experience continuous false alarms triggered by sudden cloud cover, wind-blown foliage, shadows, and camera auto-exposure adjustments when using standard motion detection.
ASTRION: AI Logistics Support Agent
Source-grounded support agent for logistics operations that answers order, ticket and policy questions from SOPs and signed customer agreements, computes fees and credits in code, and changes nothing without confirmation.
Logistics support answers depend on order records, open tickets and contract terms, and figures such as cancellation fees and service credits must be exact. A model that writes those numbers itself, cites nothing, or changes records unprompted cannot be trusted or audited.
Maritime Low-Visibility Video Restoration Pipeline
Video enhancement and image restoration pipeline engineered to mitigate fog, heavy haze, and low-visibility conditions in naval surveillance operations.
Naval defense and maritime surveillance cameras operate under severe visual degradation—dense marine fog, sea spray, night glare, and low illumination—which drastically impedes target detection.
SubSpace: AI-Powered Authentication & Chat Platform
Full-stack AI communication platform with secure session authentication, OpenRouter/Hugging Face model integration, and n8n workflow automation.
Modern web applications require seamless integration of AI capabilities with robust user session management, database security, and automated background workflows without latency bottlenecks.
