About
Currently a PhD candidate in Computer Science at NYCU, I hold dual Master's degrees in ECE from UWM and EL from CYCU. My research expertise lies in Image Processing, Pattern Recognition, and Deep Learning, with a focus on Image Restoration and Object Detection. I care about the gap between a promising model and a system that holds up in the real world.
- 01Restore
Recover detail, color, and visibility from degraded imagery.
- 02Recognize
Turn visual signals into reliable, useful information.
- 03Deploy
Keep models efficient enough for practical environments.
