摘要： An image processing system (250) and method (300) are disclosed for correcting a head pose in a video phone image, so that a frontal view is presented on a display. A disclosed head pose corrector (250) estimates the orientation of a head pose and adjusts the orientation of the head pose, if necessary, to present a frontal view. The orientation of the head pose is adjusted by generating a three dimensional model of the face surface and adjusting the orientation of the three dimensional face model to provide the desired frontal view. The head pose corrector (250) may be included in a video phone (100) to correct the head pose of transmitted or received images (or both) or may be included in a server on a network to automatically adjust the head shots of one or more participants to a video phone communication.

摘要： An arrangement for, and a method of, minimizing misdecodes of GS1 DataBar Limited (Databar-limited) symbols in a reader for electro-optically reading symbols of different symbologies, such as Universal Product Code (UPC) Version A (UPC-A) symbols, includes a data capture assembly for capturing light from a target symbol, and for generating an electrical signal indicative of the captured light; and a controller for processing and decoding the electrical signal, and for determining whether the decoded signal is indicative of a Databar-limited symbol, and for determining whether the decoded signal has characteristics indicative of a different symbology, such as the UPC-A symbol, to indicate whether a misdecode of the Databar-limited symbol has occurred.

摘要： An imaging-based bar code reader that includes an item guide to guide movement of an item including a target bar code such that target bar code passes through a field of view of the reader in a straight line. The reader further includes an imaging and decoding system to: 1) capture a series of images which include at least a part of the target bar code as the bar code is moved through the field of view of the reader; 2) sequentially analyze the series of captured images, for each captured image, identifying areas of the captured image representative of an image of the target bar code and decode decodable portions of the imaged target bar code; and 3) combining the decoded portions of the imaged target bar code using a sequence stitching method to obtain a full decode of the target bar code.

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： Random sample subsets are selected from an image. The RANSAC algorithm is used to perform robust matching between the samples of a captured image and like samples of stored images. By selecting enough samples the likelihood that all samples will be affected by lighting changes is less and therefore it is more likely that a match will be found even in the case of different lighting in the captured image than the stored images. Additionally a weighted sampling technique is used which selects samples based on likelihood of being affected by lighting changes.

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.
