“…When the sensor cannot evaluate the depth information for some pixels, as those corresponding to corners, shadowed areas, and dark objects, it assigns them a null depth value. There are various approaches to handle null depth values: differently from [ 9 ], where the null values are discarded, in [ 14 ] the authors propose a substitution process. In [ 15 ], a so-called “flood-fill” algorithm is used to resolve this problem, while in this work the null pixels are replaced by the first valid depth value occurring in the same row of the frame.…”

“…In [ 9 ], the Kinect ® sensor is placed on the floor, near a corner of the bedroom. A restriction of this setup is the limited coverage area, caused by the presence of the bed.…”

“…The results demonstrate the capability of the proposed approach to detect falls from fully-observed video sequences. In comparison, the Kinect-based approach proposed by Marzahl et al [35], which was evaluated using 55 fall depth-map videos, achieved an average fall classification accuracy of 93%. Similarly, the Kinect-based system introduced by Planinc and Kampel [36] achieved fall detection accuracies between 86.1% and 89.3% based on a dataset that includes 40 falls and 32 non-falls depth-map videos.…”
