    Abstract: A system and process to determine whether a digital image has been manipulated involves determining expected locations of non-standard pixels in the digital image, and determining a feature for evaluating the non-standard pixels. The feature in pixels of the digital image that are located at the expected locations of non-standard pixels is then measured, and a statistical measure of the feature of pixels in the digital image that are located at the expected locations of non-standard pixels is evaluated. The digital image is assessed to determine a probability that the digital image includes a manipulated portion, based on the statistical measure. The system and process can also determine a make and model of an image sensing device via an examination of the non-standard pixels.

    Abstract: The present disclosure relates to devices, systems, and methods of image pre-processing for object recognition. One method includes analyzing data about an image to determine one or more characteristics of the image that indicate whether one or more enhancements should be performed on the data, selecting one or more enhancements to consider applying to the data based on the one or more determined characteristics, analyzing the data to determine whether performing each of the selected enhancements will improve the image quality, determining which one or more enhancements to select to perform on the data based on the analysis of whether performing the selected enhancements will improve the image quality, and performing the selected enhancements on the data to improve the image quality.

    Abstract: A method that includes using a point spread function to de-blur an original motion invariant image to create a modified motion invariant image; using an edge detector to find edges in the modified motion invariant image; determining the distances between the edges and corresponding artifacts in the modified motion invariant image; using the distances between the edges and the corresponding artifacts to estimate a velocity of an object in the modified motion invariant image; generating a corrected point spread function corresponding to the estimated velocity of the object; and using the corrected point spread function to de-blur the original motion invariant image and create a resulting image.

    Abstract: Methods, devices, and systems for rolling shutter bar code imaging are described herein. One method includes initiating the imaging of a bar code by initiating a sequence of procedures to accumulate a charge in a first row of pixels as they are exposed to light thereby capturing data to create a first row of the image of the bar code at a first time, initiating the sequence of procedures to accumulate a charge in a subsequent row of pixels as they are exposed to light thereby capturing data to create a subsequent row of the image of the bar code at a second time, actuating a light source to illuminate the bar code at multiple specific times during a pre-determined timing sequence, and de-blurring the image data for each row based on the specific times during the pre-determined timing sequence that the light source was actuated.

    Abstract: A system receives data associated with an orphaned package, compares the data associated with the orphaned package to package data in a database, generates a list of candidate packages based on the comparison, and identifies the orphaned package as a function of the list of candidate packages.

    Abstract: Methods, devices, and systems for cross-sensor iris matching are described herein. One method includes capturing a first image of an iris using a first sensor, capturing a second image of an iris using a second sensor, and determining whether the iris in the first image matches the iris in the second image based on characteristics of the first sensor and the second sensor and image quality of the first image and the second image.
