Abstract: Fuel dispensing transactions may be accomplished by a variety of systems and techniques. A fuel dispensing device may include a payment module, a data entry device, and a customer display. The payment module may receive a first communication from a point of sale device requesting an encrypted response and receive a second communication from the point of sale device requesting an unencrypted response. The module may match the first communication to a first corresponding library entry, match the second communication to a second corresponding library entry, determine a user response based on one of the first corresponding library entry or the second corresponding library entry, where the user response defines one of the encrypted response based on the first corresponding library entry or the unencrypted response based on the second corresponding library entry, and use the corresponding library entry to generate a visual customer display requesting the user response.

Abstract: In video motion estimation an initial candidate motion vector is generated for each block and a vector error is determined as for example a DFD. Spatial gradients of pixel values are calculated and used to refine the initial candidate motion vector. The relative contribution of the spatial gradients to the refinement process depends on the vector error.

Abstract: This disclosure provides various embodiments of systems and methods for secure communications. In one aspect, the system includes a secure payment module (SPM) in a fuel dispenser and a point-of-sale (POS) system. The POS system stores a public key certificate uniquely identifying the SPM and is configured to dynamically generate a first session key. The POS system encrypts the first session key with a public key associated with the public key certificate, and transmits the encrypted first session key to the SPM. The SPM, which stores a private key associated with the public key certificate, is configured to receive and decrypt the first session key. The SPM is further configured to receive a set of magnetic card data from a card reader, encrypt the set of magnetic card data with the first session key, and transmit the encrypted set of magnetic card data to the POS system.

Abstract: A multimode system for receiving data in a retail environment includes: a secure input module for receiving high security input and low security input from a customer, the high security input to be communicated by the secure input module in cipher text, and the low security input to be communicated by the secure input module in plaintext. The multimode system is adapted to operate in a high security mode and a low security mode. The multimode system is adapted to enter the low security mode upon detection by the multimode system of a security breach condition. In the high security mode, the secure input module accepts low security input and high security input. In the low security mode, the secure input module accepts the low security input and does not accept the high security input.

Abstract: An array of pixel-to-pixel dissimilarity values is analysed to select a pixel which has a low pixel-to-pixel dissimilarity value and which has neighbouring pixels which have a low pixel-to-pixel dissimilarity value. Each pixel-to-pixel dissimilarity value represents a difference between the value of a pixel in a first spatial pixel array representing a first image and the value of a corresponding pixel in a second spatial pixel array representing a second image. The pixels neighbouring the current pixel are divided into at least two polar sectors. The current pixel is selected when the current pixel and the pixels of at least one polar sector have low dissimilarity values.

Abstract: In for example the assignment of motion vectors, an array of pixel-to-pixel dissimilarity values is analyzed to identify a pixel which has a low pixel-to-pixel dissimilarity value and which has neighboring pixels which have a low pixel-to-pixel dissimilarity value. The pixel-to-pixel dissimilarity values are filtered with a filter aperture decomposed into two or more sectors with partial filters applied respectively to each sector. Outputs of the partial filters are combining by a non-linear operation, for example taking the minimum from diametrically opposed sectors.

Abstract: A method of identifying the left-eye and the right-eye images of a stereoscopic pair, comprising the steps of comparing the images to locate an occluded region visible in only one of the images; detecting image edges; and identifying a right-eye image where image edges are aligned with a left hand edge of an occluded region and identifying a left-eye image where more image edges are aligned with a right hand edge of an occluded region.

Abstract: A method for repairing scratch impairments in which brightness values for a set of points within a narrow region of the impaired input image that is aligned with an expected scratch direction are modified in a scratch repair process; and the scratch repair process is controlled in dependence upon the relationship between the impaired brightness values and corresponding modified brightness values.

Abstract: An image or other sample processor has a resampling filter adapted to provide output samples at an output sampling frequency which can be selected to be higher or lower than the input sampling frequency. The width of the resampling filter aperture is scaled according to either the input sampling frequency or the output sampling frequency so as to obtain the wider of the two possible filter apertures.

Abstract: When mixing cutting between video cameras viewing a common scene from different viewpoints, geometric transforms that vary from image to image are applied to one or both camera outputs so as to create an apparent point of view that moves along on a path joining the viewpoints of the cameras.

Abstract: A device for entering information securely in a customer transaction is described. The device may include a keypad comprising a set of full travel keys for transmitting a first set of data and a set of minimal travel keys for transmitting a second set of data. A subset of the full travel keys may be operable to receive numerical entries, and a subset of the minimal travel keys may be customized to perform one or more nonnumeric functions. A controller is connected to and receives data from one or more components of the keypad. The device may be used in a fuel dispenser system or another environment where a customer transaction occurs.

Abstract: First image data at a lower sampling frequency is up-sampled in a sampling ratio N:M to a higher sampling frequency in an up-sampling filter; and, second image data at the said higher sampling frequency is down-sampled in a sampling ratio M:N to the said lower sampling frequency in a down-sampling filter where the combination of the up-sampling filter and the down-sampling filter is substantially transparent and every filtered sample is formed from a weighted sum of at least two input samples.
