Part-Pose Guided Amur Tiger Re-Identification

2019 IEEE/CVF International Conference on Computer Vision Workshop (ICCVW), 2019
In this paper, we present our solution to tiger re-identification (re-ID) in both the plain and the wild tracks in the 2019 Computer Vision for Wild life Conservation Challenge (CVWC2019). We introduce a novel part-pose guided framework for the tiger re-ID task, which consists of two part streams and one full stream based on the pose characteristics of

Amino acid sequence of the Amur tiger prion protein

Virus Research, 2006
Prion diseases are fatal neurodegenerative disorders in human and animal associated with conformational conversion of a cellular prion protein (PrP(C)) into the pathologic isoform (PrP(Sc)). Various data indicate that the polymorphisms within the open reading frame (ORF) of PrP are associated with the susceptibility and control the species barrier in ...
