Algoritmo Non-Local Means e Otimizações.
… to enhance the visualization of images. The Non-Local Means algorithm has great results in noise removal, although its computational complexity is high, making the algorithm not viable for practical use. Many papers have been presented with the objective of enhance the performance of the filter …

Optimization of Non-Local Means filtration for Cone Beam Computed Tomography
… forming a 3D representation of the object. Non-local means (NLM) denoising was applied to the X-ray images before they were used in the back projection algorithm. NLM was implemented for the graphics card and runs in real time while the X-ray images are taken. Compared to current denoising …

Sampling spatial sediment variation in gravel-bed streams
… hypothesis testing to systematically analyze local means throughout the sampled area and locate sediment boundaries. Once the boundaries are located, stones from the composite grid sample falling within the boundaries of a particular deposit can be analyzed as separate grid samples …

Patch-based Denoising Algorithms for Single and Multi-view Images
… search windows in the input images. The non-local means algorithm is adapted for filtering these noisy multi-view images. The performance of both methods have been evaluated both quantitatively and qualitatively through a number of experiments using the peak signal-to-noise ratio and the mean …

The content, scope and purpose of local studies collections in the libraries of further and higher education institutions in the United Kingdom.
… examines the presence of and reasons for local studies resources in the libraries and learning centres of further and higher education institutions in the United Kingdom. The study's aims were to investigate the content and scope of local collections in academic libraries, to examine the …

Speckle applications for volumetric imaging of biological dynamics
… in the final reconstruction. We propose a non-local means based denoising method tailored for HiLo microscopy to reduce speckle noise, which computationally mitigates the trade-off between image fidelity and sectioning strength. Finally, multifocus imaging is presented in both speckle imaging …

The Olive as an Object of Rural Development: The Cultural Politics of Organic Food and the Making of the Local
… is an in-depth case study of the emergence of local organic food as an alternative rural development tool on the island of Gökçeada (Turkey). Focusing on a cluster of programs and activities identified as the Organic Project, it investigates the politics of the changing relations between …

UK Somali Diaspora Perspectives on Peace Education as means of Conflict Resolution on the National Reconciliation Process in Somalia: An Exploratory Case Study
… the use of corporal punishment practices as a means of behaviour management.<br/><br/>Findings indicate that peace education educators in Somalia lack tailored training on how to deliver peace education contents in a clan conflict context and the complex nature of politicised historical …

Community based strategies for reducing maternal mortality in Lusaka and Chongwe: A grounded theory approach
… the health facilities using different available local means. Community level prevention of haemorrhage has also greatly helped reduce death from excessive bleeding. This study also found that the active involvement of the local civic and traditional leadership helped to pool volunteers and eased …

Algorithmic Computer Reconstructions of Stalactite Vaults - Muqarnas - in Islamic Architecture
… structure. Each muqarnas element is described by means of parameters representing its type and measurements together with parameters that describe the position of the element in the muqarnas vault. A graph theoretical approach makes it possible to include the structure information of the …

An analysis of the U.S. meat industry from consumers' and processors’ points of view
… research papers on the meat industry focusing on locally processed meat. The first paper is based on a survey distributed to meat consumers throughout the U.S. with the objective of understanding their willingness to pay for locally processed meat. This goal was achieved with two economic models. …
