Published in 2019 at "Multimedia Tools and Applications"

DOI: 10.1007/s11042-019-7216-1

Abstract: Since traditional target tracking algorithms employ artificial features, they are not robust enough to describe the appearance of a target. Therefore, it is difficult to apply them to complex scenes. Moreover, the traditional target tracking… read more here.

Published in 2023 at "Journal of Chemical Theory and Computation"

DOI: 10.1021/acs.jctc.2c00737

Abstract: Finite size error is commonly removed from coupled cluster theory calculations by N–1 extrapolations over correlation energy calculations of different system sizes (N), where the N–1 scaling comes from the total energy rather than the… read more here.
