摘要： A contour-information extraction system which includes performing raster scanning of a document, detemining a position of an interpixel grid of image data in the document, detecting contour vectors for the interpixel grid in a main scanning direction, and detecting contour vectors for the interpixel grid in a sub-scanning direction. The contour vectors are detected based on a state of a group of pixels in a vicinity of the position of the interpixel grid. The system further includes determining a connection state of the detected contour vectors and extracting contour information for the interpixel grid based on the connection state of the contour vectors.

摘要： The contour vectors of an image are stored in a small storage capacity, and are enlarged/reduced in correspondence with a desired variable-magnification factor to be faithful to an input image. For this purpose, when a binary image is input from a binary image input unit (11), a contour vector extraction unit extracts contour vectors, and detects the positions of isolated points. The contour vectors are enlarged/reduced by a vector variable-magnification/smoothing unit (13), and a binary image is reproduced by a binary image reproduction unit (15). On the other hand, each of the isolated points is subjected to variable-magnification processing by an isolated point variable-magnification processing unit (14), so that its position is converted into a position corresponding to the variable-magnification factor, and points corresponding in number to the variable-magnification factor form the isolated point. Thus, the storage capacity of the isolated points can be reduced, and the isolated points are subjected to variable-magnification processing at an appropriate variable-magnification factor corresponding to the desired variable-magnification factor.

摘要： Contour vectors are extracted by an outline extraction unit from a binary image acquired by a binary image acquisition unit. An outline smoothing/zooming unit smoothes and zooms the image expressed by the contour vectors. The zoom ratio at this time is controlled by a zoom controller in such a manner that a zoom ratio obtained by combining this zoom ratio with the zoom ratio of a second zooming unit will become a desired zoom ratio. The smoothed and zoomed image data is converted to a binary image by a binary image reproducing unit. This binary image is zoomed by the second zooming unit. The zoom ratio here preferably is selected in such a manner that the zoom ratio of the smoothing zoom unit becomes unity or greater. As a result, zooming of image data expressed by vectors is no longer limited to enlargement, images can be reduced in size while still remaining faithful to the original image, and it is unnecessary to process extra data.

摘要： An edge vector extraction unit (122) extracts edge vectors from an input image, and a variable-magnification processing unit (123) performs smoothing/variable-magnification processing of the edge vectors. A vertex point adjustment unit (100) selects each of vertex points constituting an edge vector loop as a vertex point of interest, discriminates the directions of two vertex vectors, which sandwich the edge point of interest, and adjusts the coordinate position of the vertex point of interest sandwiched between the two edge vectors having a predetermined combination on the basis of the combination of the directions, thereby suppressing a deformation of an output image, which may be caused by the variable-magnification processing.

摘要： There are provided an image processing apparatus and method, which are excellent in speed, quality, and memory amount by appropriately switching a portion to be subjected to extraction of outline vector data and a portion not to be subjected to such extraction on the basis of an input binary image.For example, whether an input binary image is a character/line image region or a pseudo halftone image region is roughly discriminated in units of predetermined amounts. Only image data determined as character/line image regions is extracted, and outline vector data are extracted from the extracted image data. The extracted outline vector data are stored in a memory. The amount of data stored in the memory is monitored, and when it is determined that the amount of vector data is too large as compared to a given image amount, and the memory overflows, vector smoothing processing including variable magnification processing for a region of interest is suspended, and a binary image subjected to binary SPC processing is selected.

A binary image acquired by a binary image acquiring unit is supplied to an image area separating unit, in which the binary image is separated into a character/line draw area and a pseudo-halftone area. An image in the character/line draw area is supplied to an outline variable magnification unit, which performs extraction of outline vector data, smoothing processing thereof, and reproduction processing of a binary image. An image in the pseudo-halftone area is supplied to a pseudo-halftone image variable magnification unit, in which the image is subjected to multivalue conversion processing in units of pixels, variable magnification processing by thinning or interpolation of pixels, and binarization again. A synthesizing unit synthesizes binary images output from these variable magnification unit and outputs the synthesized image to a binary image output unit.

摘要： When an image including a composite figure made of a predefined figure and a free-form figure is scanned, the position and shape of the free-form figure and the predefined figure are appropriately adjusted. The composite figure is separated into a predefined figure and a free-form figure. With respect to the separated predefined figure, a representative point is set at a predetermined position according to the type of the predefined figure and a representative point is set for the free-form figure based on a criterion according to a type of the free-form figure. If the representative point of a predefined figure is in the vicinity of the representative point of the free-form figure, the free-form figure is corrected based on the position of the representative point of the free-form figure and the position of the representative point of the predefined figure.

摘要： An image in which at least one color component among a plurality of color components in an input color image has a resolution lower than that of the other color components is held as a base image. A rectangular region that includes an object image is extracted, a region of the object image and a region of a background image are specified in the rectangular region, and fill-up processing of the specified object image is executed in the base image. Fill-up processing executed at a boundary between the object image and the base image differs from fill-up processing executed at a boundary between the object image and the background image.

摘要： According to the present invention, the face of a subject person can be rapidly detected. An image input unit inputs an image to be processed. A photographing-position input unit inputs photographing-position information attached to the processed image. An angle-range information determination unit determines an angle range, where face detection should be performed to the processed image, on the basis of the information obtained by the photographing-position information input unit. On the basis of information indicating the determined angle range, under the control of a process control unit, a face detection unit performs face detection to the processed image input by the image input unit in predetermined angle increments. A face integration unit integrates all of face data detected by a basic-angle-range face detection unit into face information and then outputs the information.
