Until recently, the retrieval of aerosol absorption properties from space seemed so prone to error as to be almost worthless. The principal difficulty being that if the aerosol optical depth is relatively low, then the signal measured at the satellite is proportional to ωτP(θ), where ω is the singlescattering albedo, τ is the optical depth and θ is the scattering angle. It is, therefore, imposs...

In this paper an optimal framework for summarization of stereoscopic video sequences is presented, which extracts a meaningful set of video frames. Each sequence is first partitioned into shots, the disparity field, occluded areas and depth map are estimated and then a hierarchical color and depth segmentation scheme is applied to each shot, based on a multiresolution implementation of the RSST...

We consider the problem of constructing reliable minimum nd-ing networks built from unreliable comparators. In case of a faulty compara-tor inputs are directly output without comparison. Our main result is the rst nontrivial lower bound on depths of networks computing minimum among n > 2 items in the presence of k > 0 faulty comparators. We prove that the depth of any such network is at least m...

Depth measurement is one of the most important tasks in computer vision for the applications of 3-D object recognition, scene interpretation and robotics. Various methods for depth measurement have been proposed [1]. Stereo vision [2, 3] is perhaps the most popular technique to obtain the depth image of a 3-D object. It generally uses two cameras to estimate stereo disparity and then recovers t...

Determining depth of anesthesia is a challenging problem in the context of biomedical signal processing. Various methods have been suggested to determine a quantitative index as depth of anesthesia, but most of these methods suffer from high sensitivity during the surgery. A novel method based on energy scattering of samples in the wavelet domain is suggested to represent the basic content of e...

redicting how materials behave under stress is difficult, especially when only a small specimen or thin film is available for testing. One technique involves using an “indentor” to poke a probe into the material while accurately measuring the penetration depth and the force exerted. But analytical methods for inferring mechanical properties from such measurements are generally not reliable; and...

Human robot interaction is a very heterogeneous research field and it is attracting a growing interest. A key building block for a proper interaction between humans and robots is the automatic recognition and interpretation of gestures performed by the user. Consumer depth cameras (like MS Kinect) have made possible an accurate and reliable interpretation of human gestures. In this paper a nove...

The Swedish nuclear waste will be stored in copper canisters and kept isolated deep under ground for at least 100,000 years. To ensure reliable sealing of the canisters, friction stir welding is utilized. To repetitively produce high quality welds, it is vital to use automatic control of the process. A decentralized solution is designed based on an already existing temperature controller and a ...

Commercial RGB-D sensors such as Kinect and Structure Sensors have been widely used in the game industry, where geometric fidelity is not of utmost importance. For applications in which high quality 3D is required, i.e., 3D building models of centimeter‑level accuracy, accurate and reliable calibrations of these sensors are required. This paper presents a new model for calibrating the depth mea...

Recently John Turri (2015b) has argued, contra the orthodoxy amongst epistemologists, that reliability is not a necessary condition for knowledge. From this result, (2015a, 2017, 2016a, 2019) defends new account of knowledge — called abilism allows unreliable I argue Turri’s arguments fail to establish possible and false because must be
