Abstract
An image processing apparatus for generating a pattern of a recording material to be overlapped on an original image for forming an image of a target region extracted from the original image, includes an arithmetic unit calculating a feature amount of an image data included in a boundary region of the target region; a determination unit determining a degree of change of color in the boundary region based on the feature amount; and a pattern generation unit determining a gradation of the pattern of the recording material for the boundary region in accordance with the degree of change of color in the boundary region.
Claims11
An image processing apparatus for generating a pattern of a recording material to be overlapped on an original image for forming an image of a target region extracted from the original image, the image processing apparatus comprising:
- an arithmetic unit configured to calculate a feature amount of an image data included in a boundary region of the target region;
- a determination unit configured to determine a degree of change of color in the boundary region based on the feature amount;
- and
- a pattern generation unit configured to determine a gradation of the pattern of the recording material for the boundary region in accordance with the degree of change of color in the boundary region,
- wherein the determination unit is configured to determine a luminance gradient and a direction of the luminance gradient in the boundary region as the degree of change of color in the boundary region.
An image processing method for generating a pattern of a recording material for forming an image of a target region extracted from the original image, the image processing method comprising:
- calculating a feature amount of an image data included in a boundary region of the target region;
- determining a degree of change of color in the boundary region based on the feature amount;
- and
- determining a gradation of the pattern of the recording material for the boundary region in accordance with the degree of change of color in the boundary region,
- wherein determining the degree of change of color in the boundary region is determined based a luminance gradient and a direction of the luminance gradient.
A non-transitory recording medium storing a computer-readable program for generating a pattern of a recording material for forming an image of a target region extracted from the original image, the computer-readable program comprising:
- calculating a feature amount of an image data included in a boundary region of the target region;
- determining a degree of change of color in the boundary region based on the feature amount;
- and
- determining a gradation of the pattern of the recording material for the boundary region in accordance with the degree of change of color in the boundary region,
- wherein determining the degree of change of color in the boundary region is determined based a luminance gradient and a direction of the luminance gradient.
