摘要： Imaging systems, articles of manufacture, and imaging methods are described according to aspects of the disclosure. According to one embodiment, an imaging system includes processing circuitry configured to access image data of a plurality of pixels of an image, to provide a plurality of representations of the image data, to determine contrast difference between the representations of the image data for a respective one of the pixels, to identify the one of the pixels as being defective using the determined contrast difference, and to provide replacement image data for the one of the pixels identified as defective and which is different than the accessed image data for the one of the pixels identified as defective.

摘要： Provided are codes that may be applied to a sheet of paper or other surface, as well as techniques for decoding such codes. Using such codes and decoding techniques permits identification of the position of a pen (e.g., a digital pen) on the paper or other surface, by observing only a small field of the surface. Moreover, the position often can be identified even in the presence of arbitrary rotation and certain errors (e.g., due to dust or stray markings on the paper).

摘要： Systems and methods of face and skin sensitive image enhancement are disclosed. In one aspect, a face map that includes for each pixel of an input image a respective face probability value indicating a degree to which the pixel corresponds to a human face is calculated. A skin map that includes for each pixel of the input image a respective skin probability value indicating a degree to which the pixel corresponds to human skin is ascertained. The input image is enhanced with an enhancement level that varies pixel-by-pixel in accordance with the respective face probability values and the respective skin probability values. In another aspect, a facial content measurement value indicating a degree to which an input image contains human face content is ascertained. A tone-correction process is tuned in accordance with the facial content measurement value. The input image is enhanced in accordance with the tuned tone-correction process.

摘要： In a method of automatically replacing undesirable pixels in an image, a local neighborhood of pixels is identified around an undesirable pixel. In addition, secondary neighborhoods of pixels are identified and feature values of the pixels contained in the local neighborhood and each of the secondary neighborhoods are calculated. The secondary neighborhoods having feature values within a predetermined range of the local neighborhood feature value are classified as candidates for pixel value replacement. Moreover, a replacement pixel value from at least one of the secondary neighborhoods classified as a candidate for pixel value replacement is determined and the undesirable pixel value is replaced with the replacement pixel value.

摘要： Two different (d,k)-RLL codes can be used in systems such as erasable and writable dense optical disks. This is because it is typically possible to make readers capable of reading information written at a higher resolution (by a short wavelength authoring system) than the resolution that can be written by a consumer writer (using a laser of the same or longer wavelength as the reader). For one embodiment, two different decoders are used to decode the data. Alternately, we present an encoding scheme which operates with a single decoder. In one case, q1=q2 (and as a result p1

摘要： A method for compressing a digital image to be printed, the image consisting of pixels. It is determined, for blocks of pixels, whether a block contains a graphical structure that is to be maintained without loss because it is of a type that can be accurately perceived by a human observer. The block is encoded losslessly into a less voluminous format, if such a graphical structure has been found. Otherwise, the block is compressed lossily, if no such graphical structure has been found.
