Abstract: In a color correction method, a reference area is selected in a document page, which is rendered to produce image data. The reference area can be a company logo, a letter or character in a line of text, or other graphic object. The reference area need not be a set calibration chart. The image data is used by a projector to display the document page on a screen. Ambient light may cause colors in the displayed document page to be noticeably different from the intended colors specified in the document page. A camera takes a picture of the displayed document page, and a target area is identified in the camera image based on a characteristic of the reference area that was previously selected. Corrected image data is generated based on a color difference between the reference area and the target area. The projector uses the corrected image data to display the document page, this time with colors that are closer to or the same as the intended colors.

Abstract: An RFID tag having an initial range may be modified to have a reduced or increased range by printing a modification element over the antenna of the RFID tag. The modification element may function as an extension of the antenna or may function to shield the antenna. To allow for cost-efficient modification of RFID tags, multiple RFID tags may be secured on a substrate and modified together.

The method further includes transmitting the plurality of 2D images to a model generation server and generating, by the model generation server based on the plurality of 2D images, the 3D model of the target object and one or more model characteristics of the 3D model.

Abstract: Tamper detection on an article is performed by reading data from an RFID tag having an antenna with segments designed to break apart. The RFID tag is secured to the article in such a way that, when the article is tampered with, the antenna segments will break apart. Detachment would decrease the reading range of the RFID tag. An RFID reader may be used to read the data from the RFID tag. The predefined reading range (Rp) of the RFID tag, with antenna segments entact, is obtained from the data which was read by the RFID reader. The RFID reader obtains the data while located at an actual reading range (Ra) relative to the RFID tag. By comparing Ra with Rp, it is determined whether the antenna is still entact. If Ra<Rp, the antenna is likely to be broken apart, thereby indicating that the article has been tampered with.

Abstract: A method for segmenting an image containing handwritten text into line segments and word segments. The image is horizontally down sampled at a first ratio. Connected regions in the down-sampled image are detected; horizontal neighboring ones are merged to form lines, to segment the original image into line images. Each line image is horizontally down sampled at a second ratio which is smaller than the first ratio. Connected regions in the down-sampled line image are detected to obtain potential word segmentation positions. A path is a way of dividing the line at some or all of the potential word segmentation positions into multiple path segments; for each of all possible paths, word recognition is applied to each path segment to calculate a word recognition score, and an average word recognition score for the path is calculated; the path with the highest score gives the final word segmentation.

Abstract: A hybrid digital rights management (DRM) system includes a hybrid digital rights management server (RMS server) connected to first and second RMS servers and a client computer. The hybrid RMS server stores a policy mapping table that maps its DRM policies to remote DRM policies on the first or second RMS servers, and can also create policies that satisfy the schema requirements of the first or second RMS server using policies stored in the hybrid RMS server. When the hybrid RMS server receives a document protection request from the client computer, it extracts the filename extension for the document to be protected, and uses the filename extension to select one of the first and second RMS servers as a target RMS server. The document is protected by the target RMS server, and also added to a protected document database on the hybrid RMS server.

Abstract: A carbon nanotube (CNT) resonator includes: a first CNT having a first end and a second end both fixed to a substrate; and a second CNT having a first end fixed to the substrate. The second CNT creates a Van der Waals (VdW) bond with the first CNT where the second CNT overlaps the first CNT. A length of the VdW bond along a distance between the first and the second CNTs oscillates based on a DC voltage applied between the first end of the first CNT and the first end of the second CNT. An electrical current passing through the first and the second CNTs using the VdW bond oscillates based on the oscillation of the length of the VdW bond.

Abstract: A handwriting recognition method which uses an invertible label embedding (encoding) algorithm to embed character strings into an Euclidean vector space as attribute vectors, uses a CNN to learn and predict attribute vectors of handwriting images in this Euclidean vector space, and then directly decodes a predicted attribute vector into a character string using a decoding algorithm that is the inverse of the invertible encoding algorithm. No lexicon is required to decode the predicted attribute vector. Thus, this method can recognize images containing handwritten digital sequences commonly encountered in many practical applications, such as quantities, dollar, date, phone number, social security numbers, zip code, etc. which are outside of common lexicons.

Abstract: Complete removal of an underline which intersects a character may cause problems in a subsequent character recognition or conversion process, when parts of the character which coincided with the underline are also removed. To help reduce the problems, parts of underline may be removed from an image while parts of the character that coincide with the underline are maintained in the image. Areas where the character coincides with the underline are defined from a reduced version of the underline. When the underline is removed, the areas where the character coincide with the underline are maintained in a second image. The second image may then be subjected to a character recognition or conversion process with potentially fewer problems.

Abstract: A video surveillance system with real-time object re-identification capabilities, which employs an object re-identification algorithm and an edge computing architecture. An operator monitors video images from the multiple cameras, and when a target object is observed, a target image containing the object is transmitted to all video cameras for object re-identification. Each video camera has dedicated processing circuitry that performs an object re-identification algorithm to identify the target in video images captured by that camera in real time. The algorithm calculates a frequency domain similarity measure between the target image and test images captured by the camera. The similarity measure in the frequency domain is calculated as a dot product of the 1D discrete Fourier transforms of the target image data and of the test image data. The multiple cameras also transmit object re-identification results to each other to achieve more efficient and intelligent object re-identification.
