  • Patent number: 8351728
    Abstract: Filter processing is performed on an image, in which a filter kernel having coefficients corresponding to positions of pixels is applied at a target pixel position and to sample pixels positioned in the neighborhood of the target pixel position. A bin is assigned to each unique coefficient of the filter kernel. A mask having respective positions corresponding to the positions of the filter kernel is created. Each respective position of the mask indexes to the bin for the coefficient corresponding to that position. The mask is positioned at the target pixel position, and the respective pixel value of each sample pixel is accumulated in the bin corresponding to the position of the sample pixel in the mask. The accumulated pixel values in each respective bin are multiplied by the coefficient corresponding to the bin. The resultant products are summed to determine a filtered pixel value at the target pixel position.

  • Patent number: 8351691
    Abstract: A method of text extraction in color compound documents is described. The method connects similarly colored pixels of an image of a color compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global color context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local color context statistics to thereby provide the extracted text in the text blocks. Also described is a method of locating graphics objects in a color compound document image.

  • Patent number: 8348401
    Abstract: A turning operation of a head set lever is completed, and a printing head can be detached from a carriage part. By the above-described turning operation of the head set lever, a supply port insertion and extraction part connected via a link slides, a needle pipe of the supply port insertion and extraction part is brought into a state of being the farthest from the printing head, and a needle insertion and extraction lever is brought into a state in which it moves under a case wall. Thereby, an operator cannot turn only the needle insertion and extraction lever when the head set lever is in an opened state. In this manner, when the head set lever is in the opened state, the operation of the needle insertion and extraction lever, which is used for connection of the supply port insertion and extraction part to ink supply port, is restricted.
