Terrestrial laser scanning method is widely used in three-dimensional (3-D) modeling projects. Nevertheless it usually requires measurement data from other sources for full measurement of the shapes. In this study a 3-D model of the historical Mevlana Museum (Mevlana Mausoleum) in Konya, Turkey was created using state-of-the art measurement techniques. The building was measured by terrestrial l...

• Students will learn how to develop an adaptive technique that relies on autoregressive signal modeling to estimate the spectrum for a range gate of data. In particular, when a range gate has more than one type of scatterer, multiple peaks in the Doppler spectrum may appear. Thus the autoregressive parameters can be used to represent the peaks in the spectrum, which is very similar to the mode...

3D Time-of-Flight camera's images are affected by errors due to the diffuse (indirect) light and to the flare light. The presented method improves the 3D image reducing the distance's errors to dark surface objects. This is achieved by placing one or two contrast tags in the scene at different distances from the ToF camera. The white and black parts of the tags are situated at the same distance...

In this study, we propose an exchange market model with artificial adaptive agents (AGEDASI TOF) and conduct a computer simulation as a study on the artificial market. First, AGEDASI TOF is compared with a random walk model and a linear regression model in out-of-sample forecasts. The results indicate that AGEDASI TOF outperforms the other models over all forecast horizons. Next, we analyze an ...

Remote detection by camera offers a versatile means for recording people activities. Relying principally on changes in video images, the method tends to fail in presence of shadows and illumination changes. This paper explores a possible remedy to these problems by using range cameras instead of conventional video cameras. As range is an intrinsic measure of object geometry, it is basically not...
