Problems & Rationales Purpose & Specific Aims Background & Literatures Review Materials & Methods Conclusions Future works Reference

Lowering low birth rate◦ To provide the best care

Growth environment has many potential crisis◦ Sleep apnea caused by turning◦ Damage caused by hazardous areas

Crawling fall caused the damage◦ SIDS

Infants under the age of sudden death during sleep syndrome Hypoxia Trauma 跌落

嬰兒猝死症 Sudden Infant Death Syndrome (SIDS)

Poor quality of care institutions◦ Frequent accidents News◦ Nanny expertise is not enough◦ Child-care institutions caused by the accident environment

Image segmentation◦ Cut out the face region◦ To prevent foreign interference

Otsu's method◦ The gray-scale image histogram automatically determine the optimal threshold

Color analysis◦ Part of her face to find out◦ Processing using color version

The amount of feature projection◦ Level◦ Vertical

Characteristics of Matlab, the eyes look at changes in test

Image Tracking◦ Subject focus

Binary image of the body and mark the location

◦ Track record of focus Trajectory of center of gravity made the subject

Whether to enter the target range of hazardous area

Judgement of risk◦Area to determine the amount of the face image Babies

◦System can be labeled as ROI hazardous areas ROI- Edge of the bed or windows, doors and

other dangerous areas within the room

Infants and young children near the warning notice will be issued

Alert Communications◦Light News

Green - normal state is currently in infants and young children

Yellow - the situation of infant suffocation may occur and issue a warning notice

Red - Infant issued an urgent notice near the danger zone

◦Sound(Found the time to strengthen) Yellow and red light near the representatives may stifle danger zone - sound an alarm bell
