Systems and methods for generating graphical bar codes (i.e., images that contain inconspicuous graphical modulations that encode embedded information) by halftoning with embedded graphical encoding are described. In one aspect, a graphical bar code is generated by halftoning regions of an original image. The original image regions incorporate errors diffused among regions of the original image and computed based at least in part upon modulations in the graphical bar code corresponding to a graphical encoding of a message. In another aspect, a graphical bar code is decoded by generating a base image having halftone regions representative of an original image. Regions of the base image are compared probabilistically to a set of graphical code words to obtain a sequence of graphical code words corresponding to a graphical encoding of a message. The sequence of graphical code words is decoded to produce a decoded message.
摘要:
A method including modifying at least a first pixel value in a first portion of a first image frame to create a first difference between the first pixel value in the first image and a first pixel value in a first portion of a second image frame that, at least in part, represents a first code and providing the first image frame and the second image frame to a display device for display at different times is provided.

The present disclosure includes a system and method for pull based advertisement insertion. In an example of pull based advertisement insertion according to the present disclosure, content (102) to be used in a publication is received, a target revenue value for a future sale of a number of advertisements (250, 252, 254) in the publication (216) is received, a group of advertisements (250, 252, 254) that have been bid on by a number of advertisers to select from for insertion in the publication (216) is received, and a layout (116) for the content (102) and for a number of advertisements (250, 252, 254) selected from the group of advertisements is created, wherein a layout quality is associated with at least one of a number of templates, a number of template parameters, a number of content allocations, an advertisement relevance, an aesthetic quality, and a number of advertisement allocations and wherein the layout quality is above a predetermined threshold layout quality based on the target revenue value (476).

A method for reducing view-dependent artifacts in a multi-projector system includes the steps of measuring, from multiple viewpoints, projection characteristics of an image projected by a multi-projector system, estimating view-dependent projection parameters that can reduce view-dependent artifacts, and computing rendering parameters for each projector so as to reduce the view-dependent artifacts.

Embodiments of the present invention are directed to automated methods and systems for generating mixed-content documents. In one embodiment, an automated method for generating a document layout includes receiving raw text, figures, references, and semantic information as input (901), and determining an allocation (1003) of text, figures, and references for each page of a document. The method also includes, for each page of the document, determining a template (1005) for displaying the allocation assigned to the page, and scaling template fields to exhibit the text, figures, and references assigned to the page. The method then renders (1007) the document with text, figures, and references allocated to each page within appropriate scaled template fields of the template selected for each page.
摘要:
A method for tone mapping a digital image comprised of a plurality of high bit depth intensity values in linear space is disclosed. First, a plurality of liner intensity values are mapped from the linear space to a non-linear space (402). Then a left and a right boundary interval value are determined in the linear space for each of the plurality of high bit depth intensity value (404). A dither pattern is then overlaid onto the plurality of high bit depth intensity values in linear space (406). For each one of the plurality of high bit depth intensity values in linear space, one of the boundary interval values is selected, based on the current high bit depth intensity value, the left and right boundary interval values for the current pixel, and the dither pattern value overlaid onto the current pixel (408). Each of the selected boundary interval values are mapped into a lower bit depth non-linear space (410). And then the mapped selected boundary interval values are stored onto a computer readable medium.
