Overview Introduction Recaps Embedded systems Digital image processing Application project Reflections On working experience On industrial technology Future Consideration Conclusions Appendix

Introduction ITRI Information & Communications Research Laboratories

Recaps

Embedded Systems Digital Video Camera Basic computer architecture Linux OS Finite resource

Digital Image Processing Examples Restoration of image Photo enhancement Noise reduction Special effects Halftoning Face detection

Application Project Face detection Color analysis Template matching Neural networks

My Algorithm My approach Rule-based face detection Edge detection Input images from video camera Skin color detection Roughly skin color area shape analysis Possible face areas determined Search the dark points of one of the areas Check special rule of human face Output images to PC with detected faces surrounded by bold white lines if there are faces If not, just output the input image

Edge detected & Skin detected

Face detected

Far face & Two faces detected

Cont’ Distance dependent Near Far

Cont’ Overlapped multiple faces

Reflections

On working experience Ideal assumptions of theories Implementing makes experience Practical cases Ideal case Theory Should be modified

Cont’ Feed back refining Approach is not unique Other methods

On Industrial Technology Computer Science Human abilities imitation Why not make it think as human beings

Future Consideration

Conclusions Do it yourself. Ability to collect relevant documents to solve problem is important. Innovation is emphasized more than ever.
