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

11

Introduction－ The Elderly Care status and needs(1/2)

• Government measures to aging society− Healthcare− Economic security− Home Care− Leisure and education− Else

− Community Service− Consulting service, etc.

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
