Introduction- Aging symptoms(1/2)
• Physiological function deterioration− Muscle strength decreased− Osteoporosis− Hearing, vision and perception function are decreased − Thermoregulatory function decline− Intelligence decline, etc.
• Chronic Diseases− Stroke− Diabetes− Arthritis, etc.
10
Introduction- Aging symptoms(2/2)
• Mental function disorders− Dementia− Alzheimer's Disease(AD)− Depressive tendencies, etc.
• Common symptoms− Movement
◦ Walk or get lost◦ Lacking strength◦ Can not take care of themselves

Conclusion & Discussion
• The surveillance system has been built for in-door use base on video image processing
− Detect the movement in the room − Image processing algorithms
◦ Background image updating◦ Shadow elimination
− System management
25
Conclusion & Discussion
• Image processing− Stability of the image tracking and positioning− Resolve multiple objects image overlapping− Pose recognition− Personal identification
• System management• Security
26
Future Work
• Improvement program
− Robust Algorithms
• Development on TI DSP Developer Edition− TMS320DM6437
• Statistical Analysis
• System management− Privacy− Video record
