Indoor RFID localization improved by motion segmentation

A new method for indoor localization of moving objects based on RFID localization improved by motion segmentation in video sequence captured with static or PTZ video camera is presented. Data acquired by an RFID reader are used for region of interest extraction. Motion vectors are estimated for blocks within the region of interest and used for moving object segmentation. Segmentation is improved by morphological post processing. Centroid of segmented moving object is calculated and used for its position estimation. The conducted experiments show that the localization accuracy is increased significantly using the proposed method.
