Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also shown in Figure 1ly, system principle diagram of the present invention comprises: oil painting maker and the input block, output unit and the parameter control unit that link to each other with the oil painting maker respectively;
Input block is used for input color image and gives the oil painting maker;
The oil painting maker is used to create an oil painting figure layer, and the control module controlled variable that gets parms, so that image is carried out piecemeal, sublevel, statistical treatment; And the image rendering after will handling is on oil painting figure layer;
Parameter control unit is used to control oil painting maker controlled variable, comprising: paintbrush parameter and color range parameter;
The oil painting maker comprises: divide module unit, sublevel unit and statistic unit.
Output unit is used to preserve the image that is plotted on the oil painting figure layer.
See also shown in Figure 2ly, process flow diagram of the present invention may further comprise the steps:
Step 201: the input block input picture is to the oil painting maker;
Step 202: the oil painting maker carries out initialization process to input picture;
Initialization process comprises: create an oil painting figure layer, and the control module controlled variable that gets parms;
Step 203: image is carried out piecemeal, sublevel, statistical treatment;
A: piecemeal is handled
Each pixel for input color image, need be that a square is set up at the center all with this pixel, the oil painting pixel value of this pixel will be calculated by the pixel distribution in the square of place, the length of side of square is controlled by the paintbrush parameter, this parameter is equivalent to the paintbrush width that oil painting drafting person uses when drawing oil painting, paintbrush is wide more, and oil painting is just rough more, paintbrush is narrow more, and oil painting is just fine and smooth more.
The computing formula of the square length of side is:
w＝b*2+1
Wherein w is the length of side of square; B is the paintbrush size parameter; Be equivalent to when piecemeal with center pixel up and down, left and right four direction expands a paintbrush size unit.
B: sublevel is handled
A pixel is made up of R, G, three components of B, the span of each component is [0,255], three-component can be formed 16777216 rank colors, therefore the color of coloured image is very rich and varied, it is block that but the characteristics color of oil painting becomes, oil painting drafting person is when drawing oil painting, each pen all is a kind of color, so need to reduce the exponent number of color, the color range number is by the control of color range parameter, and what of color category that oil painting drafting person uses are this parameter be equivalent to, the color category that uses is many more, and oil painting is just bright-coloured more.Among the present invention, come color is carried out sublevel according to the monochrome information of color, the brightness span of color is [0,255], evenly divides according to the color range size parameter.
The computing formula that color range is divided is:
s＝(R*0.299+G*0.587+B*0.114)*n/256
Wherein s is the color range at pixel place; N is the color range size parameter; R, G, B are respectively red, green, blue three color components of pixel.
C: statistical treatment
After a pixel of coloured image carried out piecemeal, sublevel, just can add up the colouring information of this pixel place square, and then try to achieve the oil painting pixel value of this point.Statistic processes to each pixel in the square is as follows:
1) which color range calculating pixel belongs to
2) frequency with corresponding color range increases 1
3) this color of pixel value is added in three statistical values of R, G, B of corresponding color range
4) the three-component mean value of R, G, B of obtaining the maximum color range of frequency as the computing formula of oil painting pixel value oil painting pixel value is:
Wherein O is the oil painting pixel value of piecemeal central point; (i j) is the original pixel value of the capable j row point of i in the segmented areas to P; S gets 1 when the color range at the pixel place of the capable j of an i row point is the color range of frequency maximum, otherwise s gets 0; T is the maximum frequency value of color range.
Step 204～step 205: each treatment of picture result is plotted to oil painting figure layer, and preserves the oil painting image.
The present invention can be used for producing the oil painting scene, makes the oil painting film, and the oil painting cartoon is for digital oil painting technology merchant provides a kind of new method by digital picture revolution word oil painting.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
