摘要： An image is compared to a validation image to obtain a signal-to-noise ratio. The signal-to-noise ratio is used to determine validity of the image. According to an embodiment, the image includes a barcode. According to another embodiment, a minimum threshold value for the signal-to-noise ratio is set and the validity of the image is determined based on the minimum threshold value and the signal-to-noise ratio. The minimum threshold value can be determined by using respective signal-to-noise ratios resulting from comparing a valid image to a validation image and an invalid image to a validation image.

摘要： Methods and apparatus are provided for low resolution item identification. An image of an unknown item is captured and quantized to greatly lower the resolution of the image. The quantized image data of the unknown item is compared to a plurality of the quantized image data for known items. The comparison includes using a signal-to-noise ratio calculated using the quantized image data for both the unknown and known items. A match is found when the calculated signal-to-noise ratio is above a predetermined threshold value.

摘要： Systems and techniques for identification of items using radiofrequency identification (RFID) tags exhibiting a high sensitivity to signals such as signals emitted by an RFID reader. An RFID tag includes an amplification circuit operative to detect and amplify a signal received from an RFID reader, in order to allow for processing of and response to the signal. The amplification circuit may be powered by a battery, suitably a flexible printable battery. Alternative or additional power sources may be used, such as a solar cell or a magnetic coupling, and depending on the design and operation of the tag, these power sources may be used instead of the battery or to recharge the battery if required.

摘要： Apparatuses, methods and systems used to reduce the time needed to process images of a bar code or optical code captured by a image bar code scanner. Image bar code scanners read bar codes or optical codes by capturing digital images of the codes using an image capture device and then processing the captured images to decode the optical code or bar code. The processing time is reduced by rotating the images to align the axis of the codes contained in the captured images with the rows of photo detectors in the image capture device.

摘要： Systems and techniques for using signal to noise ratio information to enhance bar code scanning accuracy. Noise information affecting bar code scanning operations is stored and a scan signal is monitored. Upon detection of a scan of a bar code, the signal strength of the scan signal is evaluated and signal to noise ratio values are computed. Signal to noise ratio information is used to favor or disfavor candidate decoding results. In addition, signal to noise ratio thresholds are set according to appropriate criteria. Decoding results are evaluated using the signal to noise ratio thresholds and accepted or rejected depending on whether the thresholds are met. In addition, thresholds for recognition of transitions based on peaks may be set based on expected noise affecting the scan signal, and allowed or excluded based on whether a rise from a negative peak, or fall from a positive peak, meets the threshold.

摘要： Systems and techniques for managing product inventory and pricing and product information. A moving camera platform is directed to desired locations in an environment to capture visual information relating to shelf labels affixed to shelves in the environment and visual information relating to products on the shelves. Image recognition is performed on the visual information to extract information on the shelf labels. The information from the shelf labels is compared against corresponding stored information, and mismatches between the shelf label information and the stored information are noted. Image recognition is also performed on the visual information to extract inventory information of the products. The inventory information is also compared against corresponding stored information, and mismatches between the inventory information and the stored information are also noted.
