An image processing apparatus includes a separation unit which determines the attribute of data contained in input document image data and separates the document image data into areas by attributes, an extraction unit which extracts, from the separated areas, an area of a graphics image as a target of vectorization processing, a determination unit which determines whether the attribute of the area of the graphics image is a clipart area or a line drawing area including a line drawing, and a vector conversion unit which performs vectorization processing corresponding to the attribute of the graphics image based on the determination result of the determination unit.
摘要:
An image processing apparatus determines the attribute of a pixel block, which is composed of a prescribed number of pixels extracted from image data, and the attribute of an area in which each pixel of the pixel block belongs. Then, based upon the determined attribute of the image block and the determined attribute of the area in which each pixel belongs, the apparatus subjects the image data to processing, pixel by pixel.

摘要:
Illumination information indicating the center of illumination and lightness change direction is acquired from an image, and the image is divided into regions for respective colors based on the acquired illumination information and color information of respective pixels included in the image. Especially, thresholds in clustering are set step by step in accordance with the lightness change direction from the center of the illumination information, and the image is clustered to the regions for respective colors according to the thresholds which are set step by step.
摘要:
An image processing apparatus determines an attribute of a block image based on the attribute of the block image determined based on a color distribution characteristic amount of the block image and the attribute of the block image determined based on an edge characteristic amount of the block image.
摘要:
An image processing apparatus comprises an attribute determination unit that divides image data into a plurality of blocks each having a predetermined number of pixels and determines an attribute of each of the divided blocks that indicates whether or not the block includes a character; a connected area extraction unit that extracts a connected area in which pixels having the same pixel characteristic are connected sequentially, from each of the divided blocks; and a foreground/background determination unit that selects a foreground/background determination method to be used for a processing target block, based on the attribute of the processing target block, the attribute of a first adjacent block that is adjacent to the processing target block, and the extracted connected areas, and determines whether a connected area of the processing target block among the extracted connected areas is the foreground or the background, using the selected foreground/background determination method.
摘要:
An image processing apparatus includes a block background/foreground determination unit which determines, based on a block attribute and quantized color information, whether each connected area is a foreground or a background, a block background/foreground attribute determination unit which determines, based on the block attribute, the attribute of a connected area determined to be the foreground of the block and the attribute of a connected area determined to be the background of the block, and a block background/foreground attribute information recording unit which records and holds information of the attribute of the block and the attribute of each connected area.
