Abstract: A method for tracking of an object with a detection device, using electromagnetic scanning signals, a plurality of target data is determined, where each target data comprises a position value. From at least a part of the target data a bounding data is determined. The object is tracked by determining a development of the bounding data. Where for determining the bounding data at least a part of the target data is grouped into clusters, a weighting value for the target data of at least one cluster is determined from the target data of the respective cluster, the bounding data is determined from weighted target data, where the weighted target data each are determined from the respective target data weighted by the weighting value of the cluster to which the target data belongs.

Abstract: Methods and systems for monitoring a well-being of a target are disclosed. In a method embodiment, data representing a process electric potential signal is received by a computer system. The process electric potential signal may be generated at least in part by one or more electric potential sensors in response to the detection of a change in an electric field of a target spaced apart from the one or more electric potential sensors. The method may further include identifying, using the computer system and based at least in part on the data electronically received by the computer system, a recurring pattern in the received data. The method may also include determining, using the computer system and based at least in part on the received data, whether a deviation from the recurring pattern transgresses a threshold. The deviation may comprise a subset of the data electronically received by the computer system.

Abstract: A video based method to detect volatile organic compounds (VOC) leaking out of components used in chemical processes in petrochemical refineries. Leaking VOC plume from a damaged component has distinctive properties that can be detected in realtime by an analysis of images from a combination of infrared and optical cameras. Particular VOC vapors have unique absorption bands, which allow these vapors to be detected and distinguished. A method of comparative analysis of images from a suitable combination of cameras, each covering a range in the IR or visible spectrum, is described. VOC vapors also cause the edges present in image frames to loose their sharpness, leading to a decrease in the high frequency content of the image. Analysis of image sequence frequency data from visible and infrared cameras enable detection of VOC plumes. Analysis techniques using adaptive background subtraction, sub-band analysis, threshold adaptation, and Markov modeling are described.
