Hand Pose Estimation from Camera Images of Ring-shaped Markers

This paper describes hand pose estimation from camera images of ring-shaped markers. The ring-shaped markers are employed to more simplify the measurement than measurement with conventional reflective markers. Using results of the pose estimation of the ring-shaped markers, the entire finger poseis estimated with an atomical constraints on finger kinematics.

<P><B>Abstract</B></P> <P>We report the scanning tunneling microscope (STM) observation of the Li<SUP>+</SUP> ion endohedral C<SUB>60</SUB> on Cu(111), prepared by means of evaporation of a high-purity Li<SUP>+</SUP>@C<SUB>60</SUB>[PF<SUB>6</SUB> <SUP>−</SUP>] salt. The electronic state of Li<SUP>+</SUP>@C<SUB>60</SUB> in the Li<SUP>+</SUP>@C<SUB>60</SUB>[PF<SUB>6</SUB> <SUP>−</SUP>] salt was also determined using photoemission and X-ray absorption spectroscopy, along with the density functional theory (DFT) calculations. In the salt, Li and PF<SUB>6</SUB> had nearly single positive and negative charge, respectively; thus the C<SUB>60</SUB> cage was practically neutral. The salt decomposed under ultra-high vacuum while heating at 400 °C. This allowed the selective deposition of Li<SUP>+</SUP>@C<SUB>60</SUB> on Cu(111). Although secondary-ion mass spectroscopy of the deposited Li<SUP>+</SUP>@C<SUB>60</SUB> film showed a decrease in the Li-content during evaporation, Li<SUP>+</SUP>@C<SUB>60</SUB> was successfully identified using STM. The DFT calculations of Li<SUP>+</SUP>@C<SUB>60</SUB> on Cu(111) suggested that the Li<SUP>+</SUP> ion was singly charged and the location of the Li<SUP>+</SUP> ion was displaced in an upward direction, which altered the local density of states in an upper section of C<SUB>60</SUB>, especially for LUMO+2. The calculated results were mostly in agreement with the bias-dependent STM and dI/dV images. However, an inconsistency was observed between the calculation and experiments in case of empty state imaging where tip-induced displacement of the Li<SUP>+</SUP> ion may occur.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
