Abstract: A layer on the reverse side of an imaging member provides excellent crack resistance to the imaging layer(s) on the front side. The crack-deterring backing layer can be a laminated self-adhesive, such as tape, or a coating. Because the crack-deterring backing layer is on the reverse side, it does not affect the electrical properties of the imaging member. Overcoat layers may be used whose function is limited to improved scratch resistance.

Abstract: A method and or a device for comprehensive temperature calibration of a full width array (FWA) image sensor may minimize loss of productivity and/or image quality. Multiple temperature sensors disposed along a width of the FWA image sensor may provide temperature points used to correct for temperature shifts in output of individual pixel sensors of the FWA image sensor. Under control of a microprocessor, a real-time correction may be calculated for each pixel of the FWA image sensor. The correction may be based upon a real-time temperature profile of the FWA image sensor and temperature dependent factors of at least one calibration equation. The factors may be predetermined, or be determined at factory test, at warm-up or at a specified time.

Abstract: As provided herein, there are supplied teachings to systems and methods for resizing a halftone image using halftone tile parameters. One approach entails receiving into a digital imaging system, a digital halftone image and a desired resizing factor for the digital halftone image. Subsequently the system will define cells within the digital halftone image and determine from those cells, a number of halftone tile seams to suitable for manipulation. The orientation of these halftone tile seams is dictated by the received desired resizing factor. The energy of the number of halftone tile seams is determined according to an energy metric so as to provide indication of at least one low energy determined halftone tile seam. A resizing of the halftone image is then performing by manipulating at least one low energy halftone tile seam in the halftone image. The resized halftone image may then be printed on a printer.

Abstract: System and method of generating feature descriptors for image identification. Input image is Gaussian-blurred at different scales. A difference of Gaussian space is obtained from differences of adjacent Gaussian-blurred images. Key points are identified in the difference-of-Gaussian space. For each key point, primary sampling points are defined with three dimensional relative positions from key point and reaching into planes of different scales. Secondary sampling points are identified for each primary sampling point. Secondary image gradients are obtained between an image at a primary sampling point and images at secondary sampling points corresponding to this primary sampling point. Secondary image gradients form components of primary image gradients at primary sampling points. Primary image gradients are concatenated to obtain a descriptor vector for input image.
