SVD-based watermarking algorithm is one of the most preferable algorithms for copyright protection due to its singular values (SVs) that have outstanding stability and represents intrinsic algebraic image properties.Hence, there is a good trade-off between robustness and imperceptibility.However, most SVD-based algorithms have been tested against c
Presence of the Jehol Biota turtle Ordosemys liaoxiensis in the Early Cretaceous Hengtongshan Formation of southern Jilin Province, China
Recently, a vertebrate assemblage of the Jehol Biota has been reported from the Early Cretaceous Hengtongshan Formation of Xingling Town, Meihekou City, Jilin Province, China.It is dominated by the fishes Lycoptera and Sinamia and the sinemydid turtle Ordosemys.Here, we describe the turtle specimens and referral to Ordosemys liaoxiensis, otherwise
Person Re-identification Based on Feature Location and Fusion
Pedestrian appearance attributes are important semantic information distinguishing pedestrian differences.Pedestrian attribute recognition plays a vital role in intelligent video surveillance,which can help us quickly screen and retrieve target pedestrians.In the task of person re-identification,we can use attribute information to obtain fine featu
A Global Monitoring Practice in the Making
In this paper, we examine a global assessment practice in the making: the measurement procedures proposed by the international community to monitor the Sustainable Development Goals (SDGs).Our focus is on SDG 4, which requires UN member states to ensure inclusive education systems in order to realise the right to Deadlocks education for all, includ
