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 facesIf 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

TheoryShould 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.
