Embedded Active Vision System Based on DSP

Shanghai Jiao Tong University, 2001-2003

Description

Designed and built a complete DSP-based embedded active vision system that autonomously tracks fast-moving objects in real time. Developed the full stack end-to-end: image capture/processing hardware, stepper motor-driven pan/tilt mechanism, and object recognition and tracking software, implemented in Assembly, C, and VHDL.
