Drivable free space information is vital for autonomous vehicles that have to plan evasive maneuvers in realtime. In this paper, we present a new efficient method for environmental free space detection with laser scanner based on 2D occupancy grid maps (OGM) to be used for Advanced Driving Assistance Systems (ADAS) and Collision Avoidance Systems (CAS). Firstly, we introduce an enhanced inverse...

a field study was undertaken with four farming systems (fs) such as; grasses and fodders, agro-forestry, agriculture (new farming systems) and shifting cultivation (old practice), to investigate the effect of land use on the soil properties, erosion and crop productivity on a loamy acidic alfisol. besides crops, the livestock were also kept and their dropping were incorporated in the respective...

Introduction Different implementations of the Dixon technique (1) have been used to quantify fat and water in various parts of the human body. In most applications, the 3-point Dixon technique with Bo correction is preferred over simple suppression methods because of its robustness in the presence of Bo inhomogeneities (2). It is also superior to the saturation techniques from an SNR standpoint...

S. H. Kwok The Hong Kong University of Science and Technology Department of Information and Systems Management Clear Water Bay, Kowloon, Hong Kong Abstract. Out-of-gamut problems exist in color image processing and color reproduction in different devices. Extensive research has been done on transforming out-of-gamut colors to the inside of the output device’s color gamut for color reproduction....

This paper presents the application of the multifrequency range imaging technique (RIM) on the Chung-Li VHF radar during several experiments between 2008 and 2013. By using this technique it is possible to get a better range resolution than the original radar pulse range gate. Hence very thin structures are observable continuously in range and time. This technique is well known in the radar atm...

We present a technique that improves the efficiency of word-lattice parsing as used in speech recognition language modeling. Our technique applies a probabilistic parser iteratively where on each iteration it focuses on a different subset of the wordlattice. The parser’s attention is shifted towards word-lattice subsets for which there are few or no syntactic analyses posited. This attention-sh...

A digital phase shifting technique capable of quantitatively determining the phase of holographic interferometric displacement fringes is presented. This technique uses computer control to take data and calculate surface deformation. The phase value at each detector point can be calculated by taking four successive intensity data frames with the reference phase shifted between each frame. The d...
