摘要： An image processing method and image processing apparatus which can execute vector conversion processing by appropriately dividing a clipart image including gradation into regions are provided. To this end, a color document image including a clipart image having an area of gradation is input, the clipart image is selected, and outline information of the clipart image is extracted. The color document image is separated into an achromatic color area and a chromatic color area, which are respectively divided into a plurality of regions. Of the plurality of regions of each of the achromatic color area and the chromatic color area divided in the dividing of region step, regions which meet a set condition are integrated. After that, the clipart image is converted into vector data using a region group after integrating of region and the outline information.

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： A region separation unit separates an inputted color document image into a plurality of types of regions such as a character region, a clip art region and a photo image region, and a clip art region extraction unit identifies the clip art region from among the separated regions. A clip art region dividing unit divides the clip art region based on the color features of the clip art region, and a clip art background identify unit identifies the background portion of the clip art region from among the divided regions. A filling unit for filling portions other than the background of a clip art fills a portion of the clip art other than the background with the background color, and a JPEG compression unit compresses the result obtained from the process for filling a clip art portion.
