摘要： An image processing apparatus can generate a vector sequence representing each color region of a color image. The image processing apparatus divides the image into plural regions based on attribute information of the image, and extracts region boundary information relating to a boundary line between different regions. The image processing apparatus generates inter-edge point vector data for each boundary connecting a first edge point to a second edge point corresponding to intersections of boundaries between neighboring regions, based on the extracted region boundary information. The image processing apparatus identifies one or more inter-edge point vector data representing a boundary of each divided region based on the generated inter-edge point vector data, and generates individual region vector data.

摘要： Disclosed is an image processing apparatus in which vector data from which noise has been removed and amount of data reduced can be generated in ideal fashion with regard to an illustration area selected from a document image. The document image is input to the apparatus and is segmented into a plurality of areas. A clip-art image is selected from these areas and a plurality of clusters are generated with regard to this image area. When a small area included in the plurality of clusters is determined as a noise, the noise is eliminated by combining the small area with a adjacent cluster. After noise is removed, the cluster group eventually obtained is converted to vector data.

摘要： An image processing apparatus, image processing method, and program which enable generation of vector data capable of replicating a clipart region of a raw image as faithfully as possible are provided. To accomplish this, a raw image is segmented into region images according to attributes. From the segmented region images, a region image having a predetermined attribute is cut out from the raw image. At least one representative color which configures the predetermined region image is decided based on an appearance color of the cut out predetermined region image. A color image having the decided representative color is extracted from the predetermined region image. A contour line of the extracted color image is extracted. An edge image within the predetermined region image is extracted. The extracted contour line is corrected based on the extracted edge image. Using the corrected contour line, vector data of the predetermined region image is generated.
