Real-time privacy filtering before video storage or transmission
FPGA-Based Embedded Vision System
Description:
Built an on-device computer vision system that detects privacy-sensitive visual content and triggers selective Gaussian blur masking in real time.
Highlights:
· Designed a hybrid ARM/FPGA architecture for live video processing.
· Used sliding-window CNN inference to produce bounding boxes.
· Optimized a lightweight 32×32 CNN to 26 KB and reached an estimated 6 FPS.

Gaussian Blur Masking
Technical Stack:
I designed the system architecture, developed the lightweight CNN pipeline, optimized the model for edge deployment, and implemented the privacy-masking logic for real-time video processing.
Because the system needed to run under hardware constraints, I optimized the model through hard-negative mining, pruning, and INT8 quantization. This reduced model size to 26 KB while maintaining real-time feasibility, reaching an estimated 6 FPS against a 5 FPS target.
My Role:
Optimization:
I built an embedded computer vision system that detects privacy-sensitive visual content before frames are transmitted or stored. The system uses ARM Cortex-A9 inference to identify regions of interest and a custom Verilog masking block to apply selective Gaussian blur in real time.

What I built:
Results:
Emerging Prosthetics is a cost-conscious prosthetic arm project designed to make prosthetic technology more accessible for amputees and non-amputees alike. I built the system using EMG muscle-signal input, C++ control logic, embedded hardware, and 3D-printed mechanical components. The prosthetic was presented at four conferences and I won various awards, including a 1st place prize.
