摘要： The present disclosure relates generally to signal processing such as data encoding and data hiding for product packaging and other printed objects. One embodiment embeds an information signal in a spot color for product packaging. The spot color is screened, and overprinted with process color tint. The tint is modulated prior to overprinting with optimized signal tweaks. The optimization can include consideration of a detector spectral dependency (e.g., red and/or green illumination). Other embodiments and combinations are described in the subject patent document.

摘要： A figure pattern (113, 711) expressing information to be embedded (112, 713), or a position of an area in which the information to be embedded exists, is embedded in an area other than the background of image data (111, 601, 712, 1801), thereby generating image data embedded with a watermark (114, 602, 715, 1802) . Then, the figure pattern is detected from the generated image data embedded with the watermark, and embedded information expressed by the detected figure pattern or embedded information existing in an area at a position expressed by the detected figure pattern is detected.

摘要： To lighten the processing load of embedding a digital watermark in content data, a preliminary process (embedding strength map generating process) run by a preprocessing section and the main process (digital watermark embedding process) run by a man processing section are run mutually independently. Specifically, the preliminary process of the preprocessing section is run each time new content data is stored to the content data database, and the main process of the main processing section is run when a content delivery request is received from a receiving terminal (client).

摘要： Methods, devices and systems for embedding and detecting a watermark in a data stream, such as a video stream. A texture criterion is evaluated for each block of the data stream. The texture criterion measures a variation of selected characteristics associated with each element of the data stream, such as luminance and chrominance. Only those blocks that are determined to have at least a predetermined degree of variation in the selected characteristic are selected for embedding of a watermark. By providing the watermark detector with a block selector that evaluates the same texture criterion as was employed in the watermark embedder, the detector attempts detection of the watermark only in those blocks having been determined to have the predetermined degree of variation of the selected characteristic, or greater. By attempting detection only in such blocks, the number of detection computations is decreased and the watermark signal to data stream noise ratio is increased, thereby facilitating detection of even weak watermarks.

摘要： A method of printing an image having a graphic security element included therein includes receiving (42) main image data representing a main image, receiving (40) graphic security element data representing a graphic security element to be included in the main image, receiving (44) a request to print the main image, responsive to receiving the request to print the main image, determining (48) particular pixels of the main image data that are to be shifted based on the graphic security element data, and causing (50) a plurality of ink deposits to be deposited on the print medium based on the main image data including causing (52) the position of each of the ink deposits on the print medium that is determined to correspond to shifted pixels to be shifted relative to a normal position that would normally result from the main image data. Also, a system that implements the method is provided.

摘要： An image processing apparatus includes a generating unit (451) and a superimposing unit (453). The generating unit (451) generates an image carrier representing a machine-readable image pattern by using information to be embedded into a first image. The superimposing unit (453) makes a second image translucent, the second image being an image of the image carrier, and superimposes the second image onto the first image in such a manner that the second image can be mechanically read and the first image can be read by a user.
