We show how to implement stationary one-way quantum steering with strong entanglement in a cavity magnonic system that consists of two magnon modes and microwave cavity. The is driven by squeezed vacuum field generated flux-driven Josephson parameter amplifier coupled Kittel via magnetic dipole interaction. find the directivity only depends on ratio coupling rates (i.e., coherent information exchange frequencies) barely affected dissipation system. Meanwhile, can be significantly enhanced...
We present a method to enhance steady-state bipartite and tripartite entanglement in cavity-optomagnonics system by utilizing the Kerr nonlinearity originating from magnetocrystalline anisotropy.

By changing external driving...
A novel illumination-invariant change detection algorithm based on Cauchy distribution is proposed. The intensity ratios between two images are used as the feature to model and subtract background. of corresponding pixels background can obey distribution, assumed that some observed temporal variation each pixel in caused by white noise. By hypothesis testing whose decision thresholds related false alarm rate, robust be carried out. intensity, hue saturation YCbCr color space employed...

This paper presents an automatic approach for building extraction and segmentation directly from Lidar point clouds without previous rasterization or triangulation. The algorithm works in the following sequential steps. First, a filtering algorithm, which is capable of preserving steep terrain features, performed on raw clouds. Points that belong to bare earth those buildings are separated. Second, points may include some vegetation other objects due disturbance noise distribution segmented...
