A new computationally efficient framework for vehicle tracking on a mobile platform is proposed. The principal component of the framework is the log-polar transformation applied to video frames captured from a standard uniformly sampled format camera. The log-polar transformation provides two major benefits to real-time vehicle tracking from a mobile vehicle platform moving along a single or mu...

In the springs of 2000, the Forest Engineering Research Institute of Canada (FERIC) undertook a series of studies to investigate the potential of using a combination of technologies to extend log hauling operations during the traditional spring break-up period. During spring break-up, thin pavement roads are weakened, resulting in the application of government-imposed load restrictions to preve...

This paper contains a description of the Philips/RWTH 1998 HUB4 system which has been build in a joint e ort of Philips Research Laboratories Aachen and Aachen University of Technology. We will focus our discussion on recent improvements compared to the original 1997 HUB4 system and evaluate them on the HUB4'97 evaluation data. The paper will deal with 1. a rough system overview including featu...

fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...

This paper presents an efficient method for road signs segmentation in color images. Color segmentation of road signs is a difficult task due to variations in the image acquisition conditions. Therefore, a color constancy algorithm is usually applied prior to segmentation, which increases the computation time. The proposed method is based on a log-chromaticity color space which shows good invar...

We are describing the construction process of a specialized multilingual lexical resource dedicated for the archive of the Digital Silk Road DSR. The DSR project creates digital archives of cultural heritage along the historical Silk Road; more than 116 of basic references on Silk Road have been digitized and made available online. These books are written in various languages and attract people...

lack of forest management plan and forest road network caused that the traditional tree felling and processing was developed in hyrcanian forest. in this system, trees are felled, limbed and topped motor-manually. felled trees are processed with chainsaws into lumber and/or pulpwood. in order to evaluate this system, lumber processing was studied in two compartments of namkhaneh district in khe...

Observations of sediment yield from road segments in the Oregon Coast Range show that either heavy traffic during rainfall or blading the road ditch will increase erosion from forest roads. For the fine soils and high quality aggregate surfacing on the study plots, ditch blading increased sediment yield more than traffic equivalent to 12 log trucks per day. The combination of ditch blading and ...

Figure 1. Map of trip with stops (numbers) superimposed on glacial map showing two major units. Tioga is the LGM glacial advance recognized throughout Sierra Nevada. Washington advance is a local name that is not correlated beyond the study area. Dashed road lines (light grey) are unpaved. Figure 2. Location of trip and study area in NW Sierra Nevada, California. Late Pleistocene Glaciations in...

voted to overcome this problem. The lengths of routing path are O(dn 1 d ) for CAN and O(log n) for Chord, which are in fact the cost of search, where there are n nodes. In this paper, we propose an alternative indexing scheme not only relying on P2P but also on broadcasting environments. The contributions of this paper include first the reduction of routing path to nearly O(1) for road-oriente...
