Abstract

A method and apparatus are disclosed for monitoring a location using vision-based technologies and to automatically trigger the activation of a child safety feature or an alarm when a child is detected. One or more image capture devices are focused on a given location. The captured images are processed to identify the presence of a child and to initiate an appropriate response, such as sending assistance, activating a child safety feature or triggering an alarm. A number of rules can be utilized to define various child safety events. Each rule contains one or more conditions that must be satisfied in order for the rule to be triggered, and, optionally, a corresponding action-item that should be performed when the rule is satisfied, such as sending assistance, activating a child safety feature or triggering an alarm.

Claims

1. A method for automatically activating a child safety feature, comprising:

obtaining at least one image of a monitored location;

analyzing said image using video content analysis techniques to detect a child in said image; and

activating a child safety feature if said child is detected, wherein said child safety feature is one of sending assistance for said child and activating a child lock feature on an appliance.

2. The method of claim 1, wherein said child safety feature includes triggering an alarm.

3. The method of claim 1, further comprising the step of estimating the age of a person detected in said image.

4. The method of claim 1, further comprising the step of estimating the height of a person detected in said image.

5. The method of claim 1, further comprising the step of identifying a person detected in said image.

6. A method for detecting a child in a monitored location, comprising:

obtaining at least one image of said monitored location;

analyzing said image using video content analysis techniques to detect a child in said image; and

performing a predefined action if said child is detected in said monitored location; and

further comprising one of;

estimating the age of a person detected in said image; and

identifying a person detected in said image.

7. The method of claim 6, wherein said predefined action includes sending assistance for said child.

8. The method of claim 6, wherein said predefined action includes activating a child lock feature on an appliance.

9. The method of claim 6, wherein said predefined action includes triggering an alarm.

10. The method of claim 6, further comprising the step of establishing a rule defining a child safety event, said rule including at least one condition to detect the presence of a child.

11. A system for automatically activating a child safety feature, comprising:

a memory for storing computer readable code; and

a processor operatively coupled to said memory, said processor configured to;

obtain at least one image of a monitored location;

analyze said image using video content analysis techniques to detect a child in said image; and

activate a child safety feature if said child is detected, wherein said child safety feature includes one of sending assistance for said child and activating a child lock feature on an appliance.

12. The system of claim 11, wherein said child safety feature includes triggering an alarm.

13. A system for automatically activating a child safety feature, comprising:

means for obtaining at least one image of a monitored location;

means for analyzing said image using video content analysis techniques to detect a child in said image; and

means for activating a child safety feature if said child is detected, wherein said child safety feature includes one of sending assistance for said child and activating a child lock feature on an appliance.

14. An article of manufacture automatically activating a child safety feature, comprising:

a computer readable medium having computer readable code means embodied thereon, said computer readable program code means comprising;

a step to obtain at least one image of a monitored location;

a step to analyze said image using video content analysis

techniques to detect a child in said image; and

a step to activate a child safety feature if said child is detected; and

further comprising one of;

a step to estimate the age of a person detected in said image; and

a step to identify a person detected in said image.
