[1] Previous tree-ring–based Northern Hemisphere temperature reconstructions portray a varying amplitude range between the ‘‘Medieval Warm Period’’ (MWP), ‘‘Little Ice Age’’ (LIA) and present. We describe a new reconstruction, developed using largely different methodologies and additional new data compared to previous efforts. Unlike earlier studies, we quantify differences between more traditi...
introduction: nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. one of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis. materials and methods: in this work, a hybrid method based on geometric deformable models...
in this paper, an optimal algorithm is presented for de-noising of medical images. the presented algorithm is based on improved version of local pixels grouping and principal component analysis. in local pixels grouping algorithm, blocks matching based on l2 norm method is utilized, which leads to matching performance improvement. to evaluate the performance of our proposed algorithm, peak sign...

We present a system for automatic people tracking and activity recognition. This video includes the contribution of 3 papers over 2 years [1], [2], [3]. We show results on many sequences, including clips from a feature-length film and historical sports footage (all tracked completely automatically). We show results that utilize the tracker to obtain 3D reconstructions and activity descriptions ...
3d reconstruction from a single image is inherently an ambiguous problem. Yet when we look at a picture, we can often infer 3d information about the scene. Humans perform single-image 3d reconstructions by using a variety of singleimage depth cues, for example, by recognizing objects and surfaces, and reasoning about how these surfaces are connected to each other. In this paper, we focus on the...
We present an approach for video based human motion capture using a static multi camera setup. The image data of calibrated video cameras is used to generate dense volumentric reconstructions of a person within the capure volume. The 3d reconstructions are then used to fit a 3d cone model into the data utilizing the Iterative Closest Point (ICP) algorithm. We can show that it is beneficial to u...
The Northern Hemisphere temperature response to volcanic and solar forcing in the time interval 1000– 1850 AD is studied using first a set of simulations with an intermediate-complexity climate model, driven by reconstructed forcings. Results are then compared with those obtained from the seven high-resolution reconstructed temperature records for the last millenium that are at present availabl...
