A Form-Conscious Total Body Photography System for In-focus Floor Protection Optimization

Abstract

Total Body Photography (TBP) is turning into a helpful screening device for sufferers
at excessive threat for pores and skin most cancers. While a lot progress has been made, current TBP
techniques might be additional improved for computerized detection and evaluation of
suspicious pores and skin lesions, which is partially associated to the decision and
sharpness of acquired photos. This paper proposes a novel shape-aware TBP
system mechanically capturing full-body photos whereas optimizing picture high quality
when it comes to decision and sharpness over the physique floor. The system makes use of
depth and RGB cameras mounted on a 360-degree rotary beam, together with 3D physique
form estimation and an in-focus floor optimization technique to pick the
optimum focus distance for every digicam pose. This permits for optimizing the
centered protection over the advanced 3D geometry of the human physique given the
calibrated digicam poses. We consider the effectiveness of the system in
capturing high-fidelity physique photos. The proposed system achieves a mean
decision of 0.068 mm/pixel and 0.0566 mm/pixel with roughly 85% and 95%
of floor space in-focus, evaluated on simulation information of various physique shapes
and poses in addition to an actual scan of a model respectively. Furthermore, the
proposed shape-aware focus technique outperforms current focus protocols (e.g.
auto-focus). We imagine the high-fidelity imaging enabled by the proposed
system will enhance automated pores and skin lesion evaluation for pores and skin most cancers screening.
