Generation of alert events based on a detection of objects from camera images

A method comprising:

• receiving an image from an image sensor;
• detecting motion regions in the image;
• detecting one or more faces in the image;
• performing a face recognition of the one or more faces in said motion regions;
• verifying if there is at least one motion region wherein no face is detected;
• classifying one or more objects in a set of classes of objects comprising a human class only in motion regions wherein no face is detected;
• verifying if said one or more faces are included in the first collection of faces;
• triggering an alert event if a face in the one or more faces is not included in the first collection of faces;
• triggering an alert event if the one or more objects is classified as belonging to the human class.

A computer program product stored on a non-transitory computer storage medium comprising computer code instructions configured to:

• receive an image from an image sensor;
• detect motion regions in the image;
• detect one or more faces in the image;
• perform a face recognition of the one or more faces in said motion regions;
• verify if there is at least one motion region wherein no face is detected;
• classify one or more objects in a set of classes of objects comprising a human class only in motion regions wherein no face is detected;
• verify if said one or more faces are included in the first collection of faces;
• trigger an alert event if a face in the one or more faces is not included in the first collection of faces;
• trigger an alert event if the one or more objects is classified as belonging to the human class.
