Abstract: Described herein are computerized methods and systems for authentication of a physical document. An image capture device coupled to a mobile device captures a sequence of images of a physical document as at least one of the physical document or the image capture device is rotated, during which the mobile device tracks the physical document throughout the sequence of images, and adjusts operational parameters of the image capture device based upon imaging conditions associated with the physical document. The mobile device selects images from the sequence of images and classifies the physical document using the selected images. The mobile device identifies a region of interest in the physical document using the selected images and the classification. The mobile device reconstructs the region of interest, generates an authentication score for the document using the reconstructed region of interest, and determines whether the physical document is authentic based upon the authentication score.

Abstract: Described herein are computerized methods and systems for authentication of a physical document. An image capture device coupled to a mobile device captures images of a physical document, during which the mobile device adjusts operational parameters of the image capture device, resulting in a sequence of images captured using different capture settings. The mobile device partitions the sequence of images into subsets of images, wherein each subset comprises images with a similar alignment of the physical document and captured using the same capture settings. The mobile device processes the subsets of images to identify a region of interest in each image. The mobile device generates a representation of the identified region of interest using the processed images, generates an authentication score for the document using the representation of the identified region of interest, and determines whether the physical document is authentic based upon the authentication score.

Abstract: An insertable adaptor for providing a cylindrical container with a funnel and sump for collecting stored liquid centrally within the container. Preferably, the adaptor is generally in the form of a modified torus, having an inclined top wall forming a funnel, a sump for accumulating liquids collected by the funnel, an outer wall cooperating with the cylindrical wall of the container, and a bottom wall. The adapter is preferably formed monolithically, so that a hollow interior is defined by the adaptor, the hollow interior being impervious to infiltration by the stored liquid. A flexible flange projects outwardly from the adaptor, so that the adaptor resists upward displacement within the container after being forced to the bottom of the container. The sump accommodates a pickup tube of a vacuum or force operated spraying or dispensing apparatus utilizing the container as a storage receptacle for liquid to be sprayed or dispensed.
