H.: Moving object extraction with a hand-held camera (2009)
Guofeng Zhang, Jiaya Jia, Wei Xiong, Tien-tsin Wong, Pheng-ann Heng, Hujun Bao
This paper presents a new method to detect and accurately extract the moving object from a video sequence taken by a hand-held camera. In order to extract the high quality moving foreground, previous...

Influence of Melanosome Dynamics on Melanoma Drug Sensitivity (2009)
Chen, Kevin G., Leapman, Richard D., Zhang, Guofeng, Lai, Barry, Valencia, Julio C., Cardarelli, Carol O., ...
BackgroundMalignant melanomas are intrinsically resistant to many conventional treatments, such as radiation and chemotherapy, for reasons that are poorly understood. Here we propose and test a model...
We study quantum teleportation via a two-qubit Heisenberg XXZ chain under an inhomogeneous magnetic field. We first consider entanglement teleportation, and then focus on the teleportation fidelity...
As-Consistent-As-Possible Compositing of Virtual Objects and Video Sequences (2008)
Guofeng Zhang, Xueying Qin, Xiaobo An, Wei Chen, Hujun Bao
We present an efficient approach that merges the virtual objects into video se-quences taken by a freely moving camera in a realistic manner. The composition is visually and geometrically consistent...
Fast recognition of single molecules based on single event photon statistics (2007)
Dong, Shuangli, Huang, Tao, Liu, Yuan, Wang, Jun, Zhang, Guofeng, Xiao+, Liantuan, ...
Mandel Q-parameter, which is determined from single event photon statistics, provides an alternative to differentiate single-molecule with fluorescence detection. In this work, by using the...

Golgi Fragmentation Is Associated with Ceramide-induced Cellular Effects
Hu, Wei, Xu, Ruijuan, Zhang, Guofeng, Jin, Junfei, Szulc, Zdzislaw M., Bielawski, Jacek, ...
Ceramide has been shown to cause anoikis, a subtype of apoptosis due to inadequate cell adhesion. However, the underlying mechanism is unclear. Herein, we report that D-e-C6-ceramide (D-e-Cer), via...

Chen, Kevin G., Valencia, Julio C., Lai, Barry, Zhang, Guofeng, Paterson, Jill K., Rouzaud, François, ...
Multidrug resistance mechanisms underlying the intractability of malignant melanomas remain largely unknown. In this study, we demonstrate that the development of multidrug resistance in melanomas...

It is generally accepted that neuroendocrine cells regulate dense core vesicle (DCV) biogenesis and cargo packaging in response to secretory demands, although the molecular mechanisms of this process...
Kriebel, Paul W., Barr, Valarie A., Rericha, Erin C., Zhang, Guofeng, Parent, Carole A.
Chemoattractant signaling induces the polarization and directed movement of cells secondary to the activation of multiple effector pathways. In addition, chemotactic signals can be amplified and...
