A decoding system for an optical identifier includes a feature detection module configured to locate an optical identifier on an item in a captured image. The optical identifier contains encoded data, the encoded data includes information about the item, the optical identifier includes a plurality of cells, and each of the plurality of cells has one of a first state and a second state. An enhancement module configured to generate an enhanced optical identifier by selectively mapping each of the plurality of cells to one of the first state and the second state based on states of neighboring ones of the plurality of cells. A decoder module is configured to decode the encoded data contained in the enhanced optical identifier to output the information about the item.

A computer-implemented method is provided for picking a 16-bit random sequence (RN16) and generating an acknowledgement packet in a tag reading session. The method includes decoding RN16s from signals received by a plurality of antennas by treating signal interference as noise. The method further includes selecting the RN16 from the decoded RN16s based on properties of the decoded RN16s and the signals from which they are decoded in the tag reading session. The method also includes generating the acknowledgement packet based on the selected RN16.

System and method for using one or more entropically configured distinct physical features (a “IDENTROPY”) for establishing trust, accountability, and transparency with respect to physical items are disclosed. Such system and method are useful, among other things, for detecting counterfeit physical items.

A system and method for reading a barcode displayed on an object is provided. The system includes a barcode reader having a plurality of cameras communicatively coupled to an image processor, and a controller device communicatively coupled to the plurality of cameras and the image processor. The cameras are arranged to define a first opening therebetween sized to receive the object therein. The controller device triggers an operation of each camera. Each camera is operative to capture a respective image of a different corresponding portion of the surface of the object, and to send the respective image to the image processor. The image processor is configured to combine the respective images received from each camera into a composite image, and to read a barcode from the composite image.

Icons/text/images representing selections areas are placed near a machine-readable image to for retrieving an information item about a product to which the machine-readable image is associated. These selection areas can be visually represented by icons/text/images that inform the user what information will be retrieved or what action will be controlled if selected. A capturing device captures a machine-readable image together with icons/text/images representing selections areas, displays these on the screen for the user to select one of the icons/text/images. The capturing device calculates the coordinates of the selection relative to the machine-readable image using a unit of distance and perspective correction derived from the machine-readable image. These coordinates are provided to an information server associated with the machine-readable image which in turn provides the information associated to the coordinates to the capturing device.

A camera device is provided that has an image sensor having a plurality of pixel elements for recording image data of an object stream of objects moving in a direction of movement relative to the camera device and a control and evaluation unit that is configured to read and further process the image data from the image sensor, wherein the image sensor is configured as a high frequency binary image sensor that generates individual images of low bit depth at a high frame rate, In this respect, the control and evaluation unit is configured to trigger a plurality of repeated shots of individual images of the image sensor and to combine the individual images while compensating the movement of the object stream between the shots to form a common image.

An imaged-based scanner includes a housing having a lower portion, an upper portion, and an extension arm extending upward from the lower portion to the upper portion. A lower portion includes a base having an exit window and an imaging assembly mounted in that base with at least one field of view directed upwardly through the exit window. The upper portion has imaging assembly that has at least two fields of view. That upper imaging assembly is mounted such that the two fields of view extend downwardly toward the lower portion with each field of view positioned to have a central axis that is offset with respect to a center normal of the exit window.
