Based on the idea of Continuous Fuzzy Guidance Law (CFGL), a andldquo;three-phase fuzzy guidanceandrdquo; (TFG) law is proposed for the class of surface to air homing missiles. The current approach enables the guidance law to track a maneuvering target from the beginning of the launch phase up to the terminal one while itdynamically attempts to keep miss-distance, flight time and control effort...

The so-called self consistency method uses the fact that the true radar co-polar reflectivity (Zh e) and the differential reflectivity (Zdr ) can be used to predict the specific differential propagation phase (Kdp) at each radar range gate. The application of this method at S-band is relatively straight-forward as has been demonstrated in the past (e.g. Goddard et al., 1994). At C-band, one nee...

Crop phenotyping is a prerequisite to enable robots doing agricultural tasks, evaluating crop status for farm management, and relating genotypes to phenotypes for crop breeding among others. Optical three dimensional (3-D) sensors have been preferred since they provide more information about the complex plant architecture. The improvement of time-of-flight (TOF) cameras together with their redu...

Recent time of flight cameras deliver range images (2.5D) in realtime, and can be considered as a significant improvement when compared to conventional (2D) cameras. However, the range map produced has only a limited extent, and suffers from occlusions. In this paper, we investigate fusion methods for partially overlapping range images, aiming to address the issues of lateral field of view exte...

The growing market of herbal remedies worldwide could pose severe problems to consumers’ health due to the possible presence of potentially harmful, undeclared synthetic substances or analogues of prescription drugs. The present work shows a simple but effective approach to unequivocally identify synthetic anorectic compounds in allegedly ‘natural’ herbal extracts, by exploiting Q-TOF LC/MS tec...

This paper investigates motion estimation and segmentation of independently moving objects in video sequences that contain depth and intensity information, such as videos captured by a Time of Flight camera. Specifically, we present a motion estimation algorithm which is based on integration of depth and intensity data. The resulting motion information is used to derive long-term point trajecto...

The Time of Flight (TOF) system of the AMS experiment provides the fast trigger to the detector and measures the crossing particle direction, velocity and charge. AMS was operated aboard of the shuttle Discovery on June 1998 (NASA STS-91 mission) and will be upgraded and installed on the International Space Station at the end of 2003, for 3 years of data taking. The performances of the TOF duri...

Active research is underway on virtual touch screens that complement the physical limitations of conventional touch screens. This paper discusses a virtual touch screen that uses a multi-layer perceptron to recognize and control three-dimensional (3D) depth information from a time of flight (TOF) camera. This system extracts an object’s area from the image input and compares it with the traject...

With increasing herd sizes, camera based monitoring solutions rise in importance. 3D cameras, for example Time-Of-Flight (TOF) cameras, measure depth information. These additional information (3D data) could be beneficial for monitoring in dairy production. In previous studies regarding TOF technology, only standing cows were recorded to avoid motion artifacts. Therefore, necessary conditions f...

Foreground extraction for live video sequence is a challenging task in vision. Traditional methods often make various assumptions to simplify the problem, which make them less robust in real-world applications. Recently, Time-ofFlight (TOF) cameras provide a convenient way to sense the scene depth at video frame-rate. Compared to the appearance or motion cues, depth information is less sensitiv...
