The middle wave infrared remote (MWIR) images has complex scene information, low contrast ratios, and bipolar problems. To solve these problems, we propose a method that uses pyramid integral image reconstruction algorithm achieving sea-land automation segmentation. First, we calculate a gradient feature map (GFM), which extracts the structural information from an MWIR scene. Then, the GFM uses for...
This paper considers the joint antenna selection (AS) problem for a classical two-user non-orthogonal multiple access (NOMA) network where both the base station and users are equipped with multiple antennas. Since the exhaustive-search-based optimal AS scheme is computationally prohibitive when the number of antennas is large, two computationally efficient joint AS algorithms, namely max-min-max AS...
An energy-efficient fast array multiplier is proposed and designed. The multiplier operates in a left-to-right mode enabling a full overlap between reduction of partial products in carry-save form and the final addition producing the product. The design is based on the left-to-right carry-free (LRCF) multiplier. It differs from the LRCF multiplier in a much smaller on-the-fly conversion circuit of...
Interpretation of aerial images is an important task in various military and non-military applications. Image segmentation can be viewed as the essential step of extracting features in aerial images. Among many developed segmentation methods, the clustering methods have been extensively investigated and used. The determination of the number of clusters in a dataset is inherently a difficult problem,...
