Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for inserting a watermark into an image.
SOLUTION: In an image watermark insertion technique, the watermark is inserted into an adjusted digital source image which is set in boundary by a predefined "bounding rectangle". If the source image is larger (or smaller) than the rectangle, its downsizing (or enlargement) to a maximum size adjusted image completely fit into the rectangle is performed using a common factor. The watermark is inserted into the adjusted image, and at least one larger or smaller derived image is created. Then, regardless of the size of an image derived from the adjusted image containing the watermark, the detection of the inserted watermark is dramatically facilitated by the enlargement or downsizing of the image for making it fit into the rectangle again. The size of the bounding rectangle may be intrinsic in terms of a source image, or otherwise a bounding rectangle common to each group of the source images may be used.

Abstract: A method for enlarging a binary image by an arbitrary factor includes the steps of storing the image in bit sequence; rotating the image in a first direction by ninety degrees; inserting one or more rows of expansion bits along the origional horizontal axis of the image to convert i rows of bits to j rows of bits where i

Abstract: The method involves providing a digital original image, then providing a digital watermark image and, producing a watermarked image by superimposing the watermark image on the original image without changing the chromaticity parameters of pixels of the original image as watermarked. E.g. for each pixel in the watermark image that is not "transparent", it requires modifying the corresp pixel of the original image by changing the brightness but not the colour. A scanner (100) captures image data from a physical source (such as a painting or photograph) (102) and sends it to a digital computer (104). The latter includes a working storage (106) e.g. RAM an image storage system (108) (which can be, for example, a conventional hard disk drive. An image archive (110) can be, for example, a tape or disc storage.

Abstract: SOFT COPY DISPLAY OF FACSIMILE IMAGES Digital data defining images are stored in a multiplane buffer. The buffer may store plural images by restricting data corresponding to an image or image portion to less than half the bit planes of the buffer. An image is displayed by reading data from the buffer and selectively passing only a portion of the data read to a display. The data defining the images may be converted from facsimile (single bit per pixel) to grey scale format (multiple bits per pel) before being written to the buffer. The conversion relies on a table storing data definitive of the effect, on the image, of a facsimile transition (1/0 or 0/1) as a function of the location or the transition. Conversion from facsimile to grey scale is effected by examining the facsimile data for data transition and summing the effect of each of the transitions to convert a segment of facsimile data to grey scale data. A system is also disclosed for rapidly converting an image in run-end form to a reduced-resolution gray-tone image.

Abstract: A binary image is reduced in size by a method including the steps of: storing the image in bit sequence; dividing the image into transposable blocks; transposing by look up table, for each block having any nonzero data, each group of 6 bits along a first axis to a group of 5 bits; transposing by look up table, for each block having any nonzero data, each group of 6 bits along a second axis to a group of 5 bits; storing said transposed blocks.

Abstract: A method for rotating an image by 90 degrees includes the steps of: storing the image in a raster format arranged in r rows by c columns, image information in each row being stored in a number of bytes, each byte having b bits, there being c/b bytes in each row of the raster format; moving a block of the image into a temporary storage, there being n rows by m columns in the block; separating each image block into groups of bytes of rotatable size; determining for each group if all bits are the same value; rotating each group that does not have all bits the same value; storing each rotated group in an output area of the raster storage; repeating the above steps for all remaining blocks of the image.
