Encouraged by the growing interest in automatic 3D image-based reconstruction, the development and improvement of robust stereo matching techniques is one of the most investigated research topic of th...
Local density of states of chiral Hall edge states in gyrotropic photonic clusters
Local density chiral Hall edge states gyrotropic photonic clusters
2015/8/7
We have constructed the Green’s tensor for two-dimensional gyrotropic photonic clusters and have calculated their optical local density of states (LDOS). For clusters that support the chiral Hall edge...

We implement an experimental continuous variable quantum key distribution system over 24 km of optical fiber that uses discrete signaling and a continuous wave local oscillator. A secure key rate of 3...
A 120Hz Local Blinking HDR system was proposed to significantly reduce MPRT down to 3.89ms and keep high brightness almost as well as conventional LCDs, that is distinct from the prior arts, such as B...
An image fusion algorithm based on polyharmonic local sine transform (PHLST)
image fusion performance metric
2011/5/6
In this paper, we propose a novel image fusion algorithm based on polyharmonic local sine transform (PHLST). First, we apply PHLST to source image to decompose it into two components: polynomial p and...
