METHOD AND APPARATUS FOR MONITORING MOVEMENT AND BREATHING OF MULTIPLE SUBJECTS IN A COMMON BED Russian patent published in 2016 - IPC A61B5/113 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment, namely to devices for monitoring movement and breathing of two or more subjects occupying common bedding. Method for monitoring movement comprises the steps of imaging the bedding by an optical sensor, performing a motion estimation by producing motion vectors indicating the local displacement of corresponding image blocks between consecutive images, or images that are several frames apart, that are received from the optical sensor, calculating motion clusters by measuring spatial and temporal correlations of the motion vectors, segmenting the calculated motion clusters by assigning each motion cluster to a corresponding subject, based on the spatial and/or temporal similarity of the motion clusters among each other and on previous results of segmentation. Method is implemented by means of monitoring device with a machine-readable carrier including a computer program.

EFFECT: using the inventions enables to increase accuracy of monitoring.
