UBEAR In
order to broad the applicability of biometric
systems, the data acquisition constraints required for reliable
recognition are receiving increasing attention. For some of the
traits (e.g., face and iris) significant research efforts were already
made toward the development of systems able to operate in
completely unconstrained conditions. For other traits (e.g., the
ear) no similar efforts are known. The main purpose of the UBEAR data
set is to supply to the research community a new data set of ear
images,
which main distinguishing feature is that its images were acquired
from on-the-move subjects, under varying lighting conditions and
without demanding to subjects any particular care regarding
ear occlusions and poses. The data set is freely available to
the research community and should constitute a valuable tool
in assessing the possibility of performing reliable ear biometric
recognition in such challenging conditions.
The setup of the video and imaging framework is given in the above table. The video capture sequence starts with all subjects facing front and 3 meters apart from the camera sideways, it’s also required of the individual to move his head upwards, downwards, outwards, towards. After these, subjects should step ahead and backwards from the initial position. For each subject both ears were captured in two different sessions, giving a total of four videos per subject. Each video sequence was manually analyzed and 17 frames were selected according to the following criteria: - 5 frames when the subject was stepping ahead and backwards, -
3 frames of the subject’s head moving upwards, -
3 frames of the subject’s head moving downwards, -
3 frames of the subject’s head moving outwards, -
3 frames of the subject’s head moving towards. Download
