摘要： Cameras and image processing techniques are applied to the control of HVAC systems. Occupancy is detected using head-counting or motion detection. Activities are recognized in images and image sequences by machine-recognition techniques. The nature of activities, the intensity of activities, the number of occupants and their activities, etc. are all inferred from images and image sequences and used to predict current loads and/or required control signals for regulating an HVAC system.

摘要： A method and apparatus are disclosed for generating and maintaining enhanced background models for use in background-foreground segmentation. Background models are modified to contain an indication of objects that are typically stationary. Thereafter, if an object moves and has been previously identified as an object that is typically stationary, the object will not unnecessarily be identified as part of the foreground during background-foreground segmentation. In an exemplary implementation, moving objects are classified into two sets. A first set includes objects that typically move independently and a second set includes objects that are typically stationary. Generally, once an object is assigned to the second (stationary object) set, the object will remain in the background, even if the object is moved (normally, movement of the object would cause the object to become part of the foreground).

摘要： Aspects of the present invention can be configured to demultiplex an asynchronously multiplexed video signal, which comprises images from a number of different cameras. Image matching techniques are used to assign input images with states. After a period, the number of states will generally equal the number of input cameras. The states may be modeled through any number of techniques, such as histogram analysis, clustering, and hidden Markov model analysis. Input images are assigned to states, and the input images are output as being associated with the states. Zone surveillance may be performed on a series of images from one or more of the states. Any events that occur can be distinguished and reported.

摘要： The learning rate used for updating the weights of a self-ordering feature map is determined by a process that injects some type of perturbation into the value so that it is not simply monotonically decreased with each training epoch. For example, the learning rate may be generated according to a pseudorandom process. The result is faster convergence of the synaptic weights.

摘要： The position of a target lying on a plane is indicated by inputting a pointing direction which is computationally projected onto a plane. If the target is known to lie on a contour, the position is specified unambiguously. Alternatively, the position of a target can be specified by inputting its axial coordinates in successive steps. In another alternative approach, the image containing the target is translated and/or rotated and the target indicated again. The two direction projections are then used to determine the position of the target in 2-space. The direction indications may be input by a camera or other method, such as one or more radio transmitters.

摘要： The present invention relates to a device containing an automatic zoom lens, and more particularly to a zoom lens that is controlled by a processor that is linked to a gaze tracking system. As a user looks onto an object through the device, the gaze tracking system collects data relating to the position of each eye of the user. This eye position data is input into the processor where the focal point of the user is determined. The processor then adjusts the zoom lens to zoom in or out onto the object based on either a predetermined or user input zoom factor.

摘要： A system and method is provided for adaptively setting biometric measurement thresholds in a biometric measurement system. A biometric measurement system comprises a biometric sensor, an analysis unit, and an output unit. The invention comprises an environmental sensor that measures a value of an environmental parameter of the ambient environment of the biometric measurement system. The invention also comprises an adaptive threshold setting unit that adaptively sets an adjustable biometric measurement threshold in the analysis unit using a value of the environmental parameter measured by the environmental sensor. The analysis unit analyzes biometric measurements received from the biometric sensor and uses the adjusted biometric measurement threshold to take into account the influence of environmental changes.
