“…Nevertheless, in spite of their limitations, current generation of TOF based depth sensors was successfully used in several applications such as video surveillance and tracking [13], facial features detection and tracking [14], classification of moving objects [15], gesture recognition [16], documentation of heritage objects [11], robot vision and obstacle detection [17,18], safety [12]. Some authors combined TOF sensors with additional high resolution cameras [19,20] in order to overcome the limitations of the embedded CMOS camera or stereo vision systems [21,22] in order to improve effectiveness of depth perception.…”
