METHOD AND SYSTEM FOR ISOLATING FOREGROUND OBJECT IMAGE PROCEEDING FROM COLOUR AND DEPTH DATA Russian patent published in 2011 - IPC G06K9/34 G06T7/00 

FIELD: physics.

SUBSTANCE: scalar image of difference between object and background on the basis of difference between illumination difference is produced. In regions with illumination difference lower than preset threshold it is created on the basis of the difference in colour. Mask is initiated on the basis of results obtained at previous video frame wherein scalar difference image is smaller than preset threshold, if said results may be accessed. Note here that objet mask is filled with zeroes and unities wherein unity designates that relevant pixel belongs in said object or otherwise, zero. Said scalar image depth data are clusterised on the basis of several clusters. Mask for every video frame pixel position is produced using centers of gravity of scalar difference and data on depth for pixel current position. Scene background change is compensated in time y updating background image on the basis of created mask and difference image.

EFFECT: perfected procedure.
