AI Thermometer

Contactless Temperature Measurement with IR & RGB Cameras

This project uses Facial Detection and radiometric IR measurement in order to determine person’s facial temperature. Hardware and software are freely available on github. Highlights:

• DNN-based Facial Detection with RGB camera.
• Contactless temperature measurement with IR camera.
• Option for auto-calibration with external reference (blackbody).
• The project was awarded as Project of the Month by Nvidia.
• I presented AI Thermometer during a GTC’21 session

Wildfire Detecting Drone

In this project I implemented and deployed DNN-based wildfire detection with RGB camera.

• Trained DNN for fire detection
• Scrapped and hand annotated dataset of 10k fire scenes
• Trained model to achieve 94.7% accuracy and 98.7% sensitivity
• Deployed DNN on Nvidia Jetson Drone
• Tested over an 80-acre wildfire with Sacramento Metro Fire Dept

Wildfire Simulation

A project simulating and visualizing the dynamic behavior of a wildfire. Built as an evironment to train RL agents.

• Simulates the effect of wind direction on the spread
• Can run with custom fuel distribution
• Adapted the approach from this paper
• Optimized the approach from \( O(n^4) \rightarrow O(n \cdot log(n) \)
• Runs on 10M cell lattice at \( 20FPS \)
• I’m working on scaling this approach further with CUDA.

Autonomous Vehicle Camera + Radar Perception

In this project I retrofitted a 1999 Mercedes CLK with:

• RTK GNSS,
• stereo cameras,
• automotive radar
• Nvidia Jetson Nano.

Then, I trained & implemented 2D perception (mRCNN-based), radar processing pipeline & image+radar fusion. As a last step I tested the system on the road. For more information go to related paper. On the right you can watch a short video demonstrating the mask-RCNN 2D perception on SJSU campus.

Paper Search Engine

Search all AI papers on arxiv.org in \(\lt 1ms\)

The app rapidly compares user query against abstracts of all CV/AI/ML papers available on arxiv.org. I wrote it to ensure that someone didn’t come up with idea before. The app also allows you to find papers similar to your research interests.

• A typical query takes 1ms to process.
• Paste full abstract of an interesting paper to find similar papers.
• You can search 30 years of AI research in a fraction of a second!

PCB Business Card with Proto Board

A PCB businesss card with matt black soldermask looks and feels much better than a boring paper business card. It has a small prototyping area on the side, and makes a great converstaion starter! The schematic and board files are available on my github.
