|20150249779||SMOOTHING OF GHOST MAPS IN A GHOST ARTIFACT DETECTION METHOD FOR HDR IMAGE CREATION - An improved ghost-artifact detection and removal method for high-dynamic range (HDR) image creation and related apparatus are described. A binary ghost map is first generated for each image of the multiple input images by a ghost-artifact detection process, where one of the binary values indicate ghost pixels and the other indicates non-ghost pixels. Each binary ghost map is smoothed to generate a continuous-tone ghost map, by changing the pixel value of each non-ghost pixel of the binary map to a ghost value between the two binary values. The ghost value is calculated using a monotonous function of the distance between the non-ghost pixel of the binary map and the nearest ghost pixel. Ghost pixels in the binary ghost map are kept as fully ghost pixel in the continuous-tone ghost map. This method helps to reduce visibility of artifacts at ghost boundaries without losing small detected ghost regions.||09-03-2015|
|20150249774||GHOST ARTIFACT DETECTION AND REMOVAL IN HDR IMAGE CREATION USING GRAPH BASED SELECTION OF LOCAL REFERENCE - In high dynamic range (HDR) image creation, a ghost artifact detection method divides the images (brackets) into multiple tiles, and selects one bracket for each tile as the local reference bracket. The local reference brackets are selected via optimization of an objective function which includes both a component that measures exposure quality of individual tiles and a component that measures correlation between neighboring tiles. The minimization can be realized by constructing a graph for the objective function and calculating a minimum cut of the graph using a graph cut algorithm. Graph examples for three and four image sets are given. Ghost artifact detection is then performed on a tile-by-tile basis by using the local reference bracket for each tile. Ghost maps are generated this way and used for HDR image creation. This method minimizes artifacts due to inconsistencies in local reference bracket selection in areas involved in ghost-inducing objects.||09-03-2015|
|20150249771||METHOD AND SYSTEM FOR IMPROVING PRINTING EFFICIENCY IN THE PRODUCTION PRINTING ENVIRONMENT - A method and system for improving printing efficiency in a production printing environment, which includes a plurality of printers is disclosed, the method including: monitoring the plurality of printers via at least one server, wherein each of the plurality of printers are configured to provide a print job status to the at least one server; receiving an error message from at least one of the plurality of printers; selecting an operator from a list of operators assigned to the at least one of the plurality printers, wherein each operator on the list of operators is capable of fixing an error associated with the error message on the at least one of the plurality of printers; and notifying the selected operator to investigate the error message via a client device.||09-03-2015|
|20150248560||METHOD FOR SPECIFYING USER ACCESS RIGHTS FOR A DIGITAL DOCUMENT USING EXISTING RIGHTS MANAGEMENT POLICIES WITH MODIFICATIONS - A digital rights management (DRM or RMS) method allows the operator of a scanner, connected to an RMS server, to associate a digital document with user access rights that are different from the rights defined by any of the existing DRM policies on the server. The method allows the operator to choose one of the existing policies on the server, and modify the user access rights by granting rights to additional users and/or removing rights of some users that would be granted by that policy, to generate modified user access rights for a document without changing any existing policies or adding new policies. The server stores the document ID, polity ID and the user access rights (modified or unmodified) in a rights association table on the server. The method is also applicable when importing documents into the DRM system from sources other than scanners.||09-03-2015|
|20150248378||READABILITY ON MOBILE DEVICES - A method involves operating a mobile device including a screen. The method includes detecting, by the mobile device, an acceleration of the mobile device; receiving, by the mobile device and after detecting the acceleration, a request to access a document including multiple default settings; and modifying, in response to detecting the acceleration and receiving the request, a display of the document on the screen.||09-03-2015|
|20150248195||USER INTERFACE METHOD FOR MODIFYING A SELECTION LIST OF ITEMS TO ADD OR REMOVE ITEMS WHILE INDICATING ORIGINAL SELECTION - A user interface display method implemented on a computer-controlled device to allow an operator to define a list of selected items among a plurality of items available for selection. The operator starts by selecting a pre-existing list containing a number of selected items. A modified list is generated which initially contains the same items as the pre-existing list. The device displays all of the items available for selection, as well as first and second indications associated with each item initially in the modified list. Then, in response to operator inputs to add items to (or remove items from) the modified list, second indications are displayed (or removed from display) in association with the items to be added (or removed), without changing the display of any of the first indications and any of the plurality of items. The modified list is saved without changing the pre-existing list.||09-03-2015|
|20150242650||DOCUMENT CONTROL BASED ON COPYRIGHT PERMISSION WHEN PRINTING COMPILATION OF WORKS - A method for controlling copyright permissions when assembling multiple copyrighted works into a compiled file. The copyright permission level of each file is analyzed, either based on the copyright permission information present in metadata associated with the file or based on the digital file format of the file which reflects the permission level. The compiled file is assigned a permission level which is the same as or more restrictive than all of the permission level of the files in the compilation, and is generated in a format that enforces the assigned permission level. A notification may be displayed to the user to notify the use of the permission level assigned to the compiled file.||08-27-2015|
