Hi, My name is Keqiong "Claire" Xin. I'm now pursuing the Master Degree of Computer Engineering in Rose-Hulman. This is my user page for course ECE597 Embedded Linux.

Our Project

Our project in this course is ECE597: Auto HUD. All the documentation is contained in the page link.

The idea of this project is to recognize road signs with Beagleboard and camera, and display the result through the pico projector.

1. Build the sample set for training, and using Haar training program to train the samples.

2. Working on sign detection code to optimize the detection result.

3. Get the display buffer working.
