An increasing number of unknown islands, an important resource for human development, is identified based on segmentation of remote sensing image. Different from traditional digital image, remote sensing image has significant characteristics, such as multi-band, multi-source, and multi-granularity. Thus, the segmentation theory based on traditional digital image is not suitable for remote sensing...
Spatial modulation (SM) is a promising multiple-input–multiple-output (MIMO) transmission technology, which exploits the indexes of the transmit antennas for encoding information into the spatial dimension and, thus, for increasing the transmission rate. Optimal demodulation is realized by using a maximum-likelihood (ML) detector, which jointly estimates the information bits encoded into the transmit...
Endmember extraction is a very important technique in hyperspectral unmixing. Due to the fact that more applications require real or near real-time processing capabilities, high performance computing based on field-programmable gate array (FPGA) for endmember extraction has received considerable interest in recent years. In this paper, we propose a real-time implementation of maximum volume algorithms...
The principal eigenvector x1 belonging to the largest adjacency Eigen value (i.e. The spectral radius) of a graph is one of the most popular centrality metrics. The spectral radius of the adjacency matrix powerfully characterizes the dynamic processes on networks, such as virus spread and synchronization. The sum of components of the principal eigenvector, which is also called the fundamental weight...
