Autonomous Underwater Vehicles (AUVs) need positioning systems besides the Global Positioning System (GPS), since GPS does not work in underwater scenarios. Possible solutions are the Simultaneous Localization and Mapping (SLAM) algorithms. SLAM algorithms aim to build a map while simultaneously localizing the vehicle within this map. However, they offer limited performance when faced with larg...

The challenge of the cloud removal task can be alleviated with aid Synthetic Aperture Radar (SAR) images that penetrate cover. However, large domain gap between optical and SAR as well severe speckle noise may cause significant interference in SAR-based removal, resulting performance degeneration. In this paper, we propose a novel global–local fusion based (GLF-CR) algorithm to leverage complem...

BACKGROUND Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is an increasingly popular procedure with several potential advantages over traditional open TLIF. OBJECTIVE The current study aimed to compare fusion rates of different graft materials used in MIS-TLIF, via meta-analysis of the published literature. METHODS A Medline search was performed and a database was crea...

In recent years, the wavelet-based image denoising techniques mainly focus on the case that uses a single wavelet base. In fact, different wavelet bases can often effectively represents different areas or features of an image. In this paper a new image denoising method using multiple wavelet bases is proposed. First, the noisy image is denoised by various wavelet bases and then a set of the den...

Exposure fusion is an efficient method for directly fusing multi-exposure images into a high-quality low dynamic range image, without the high dynamic range (HDR) production and tone mapping process. The previous exposure fusion methods only produced an image that contains a fixed amount of details, which can not satisfy further demands for more detail information. We introduce Local Laplacian ...

We define minimal fusion systems in a way that every non-solvable fusion system has a section which is minimal. Minimal fusion systems can also be seen as analogs of Thompson’s N-groups. In this thesis, we consider a minimal fusion system F on a finite p-group S that has a unique maximal p-local subsystem containing NF(S). For an arbitrary prime p, we determine the structure of a certain (expli...

The theory of distributed detection is receiving a lot of attention. A common assumption used in previous studies is the conditional independence of the observations. In this paper, the optimization of local decision rules for distributed detection networks with correlated observations is considered. We focus on presenting the detection theory for parallel distributed detection networks with fi...
