  • Patent number: 8049930
    Abstract: A method is performed to hide a watermark in two halftone images or in a single halftone image. The halftone image contains information of the hidden watermark, and each pixel value of the halftone image is associated with a corresponding offset value. The offset value is determined according to a corresponding pixel value of the watermark and a corresponding pixel value of another halftone image. The offset value is used to compensate a corresponding input value and a corresponding original error value of the halftone image.

  • Publication number: 20100153091
    Abstract: Architecture that enables a user to perform manual word-breaking by phrase input. Phrase input is where the user inserts a phrase-key (or separator) as a delimiter that indicates to an editor application such as an IME (input method editor) the composition of a specific phrase when entering characters (e.g., Asian). The word-breaking is controlled by the user. The conversion quality is improved as the user knows the desired input and ambiguous cases are reduced. A phrase can be specified while the user is composing the characters. By selecting a phrase-key separator, the user can specify the composing characters before the characters are presented as a phrase. Moreover, the architecture includes a phrase prioritization mechanism wherein each phrase can be treated as a single entity and assigned a character identifier (ID), which is related to the sequence of a candidate list.
