Figure BDA0000120983900000104
Namely According to
Figure BDA0000120983900000106
With
Figure BDA0000120983900000107
Value, extend out or inside contract the hair image with the liquefaction algorithm at regional area, make more natural that the figure of hair image and face mates.So far the Auto-matching process is completed.The basic functional principle of liquefaction algorithm is as follows:
In Figure 15, the shade annulus represents that a radius is r maxCircular constituency.Wherein, C is the center of circle in circular constituency, when C moves to M, causes the some U in image to transform to an X, and the inverse transformation formula of this coordinate transform is formula 1.Wherein
Figure BDA0000120983900000108
Be respectively a U, X, C, M be the position vector in coordinate system in the drawings.When providing a some X, can obtain the coordinate U (accurate floating-point coordinate) before its conversion, then draw near the pixel value of the pixel of image coordinate points U before changing.Find the solution by these pixel values are carried out bilinear interpolation, derive and namely draw the pixel value of an X.So each pixel in circular constituency is carried out evaluation, just can draw the image after conversion.
u r = x r = ( r max 2 - | x r - c r | 2 ( r max 2 - | x r - c r | 2 + | m r - c r | 2 ) ) 2 × ( m r - c r ) (formula 1)
(12) if mate not accurate enoughly, the operator also can adjust by manual operations size and the position of hair image, or extends out or inside contract the hair image with liquify tool at regional area, makes hair image and face image perfect matching.
(13) then the operator can also further process the image after synthetic with the image processing method of summary, and these methods mainly comprise: hair style pruning, hair style adjustment, hair style are had hair dyed, manually improve looks or light is played up.
The method that hair style in step (13) is pruned comprises following four kinds of methods:
1. straight snips: straight snips is the hair image to be pruned as template with border circular areas.When with template, the hair image being pruned, the hair image information of template overlay area can be wiped.The operator realizes the pruning work to the hair image, as shown in figure 10 by dragging the mode of mouse.
2. tooth is cut: it is the hair image to be pruned as template with jagged irregular area that tooth is cut, by the height of regulating sawtooth and the tooth cut-off-die plate that bottom width is set up different densities.When with template, the hair image being pruned, the hair image information of template overlay area can be wiped, and the hair that the sawtooth on template is encountered will be cut into jagged breach.Each jagged breach intersects and will form the thin silky effect that thins when dragging template fast with mouse, makes the hair image after pruning not lose naturality, has more stereovision.
3. profile is pruned: as shown in figure 11, the face mask line of face image is presented on composograph, and the operator can change the zone that the face mask line covers by point on the drag wheel profile, and the information of the hair image in capped zone can be wiped.The operator simply just can wipe unnecessary hair information by the mode that drags a little like this, realizes the function that hair style is pruned.
4. hair style is cloned: the operator first gets a point on the hair image by mouse, orientate source point as.Then mouse press drag in, near the hair information source point will by the complete zone that mouse drags that copies to, can realize lengthening the effect of hair like this.
Hair style adjustment in step (13): the operator can be simply by dragging the point of appointment on the hair image, and the hair image that stretches makes it more mate face image, as shown in figure 12.On the operator drags in the point of some marks, utilize the liquefaction algorithm to being carried out image deformation as the zone of the appointment radius in the center of circle and process to drag a little in the hair image, the basic functional principle of liquefaction algorithm is consistent with the principle of the middle introduction of embodiment (11).

1. choose and dye: the operator smears the hair image by pressing the mode of mouse drag, and specifying needs the zone of having hair dyed in the hair image, and then the color of object of hair dyeing is provided, and just can easily realize changing the colouring information of application area, realizes hair dyeing effect.The mode of color change is: kept the brightness attribute of former hair color, form and aspect, the saturation attributes of color are revised.And in the place that the regional area of the hair image that is modified color attribute is connected with the part that is not modified, the effect that color is revised is that gradual manner weakens gradually, makes the whole structure after dyeing more natural.
2. colour code hair dyeing: the operator provides the color of object of hair dyeing, just can change the integral color information of hair image, realizes whole hair dyeing effect.The mode of color change is: kept the brightness attribute of former hair color, form and aspect, the saturation attributes of color are revised, made the stereovision of the hair image after being colored well be kept.
3. multiple dimensioned hair dyeing: on the hair image, acquiescence superposeed multilayer and the onesize figure layer of hair image, these figure layers all possess respectively the information of certain regional area of hair image.The operator only need to provide and want the color of object of having hair dyed just can change the figure layer color that these possess local region information like this, realizes like a cork the hair dyeing of regional area.The mode of color change is the brightness attribute that keeps former hair color, and form and aspect, the saturation attributes of color are modified, and makes the stereovision of the hair image after being colored well be kept.Like this operator can be very easily to hair some specific zones dyeing, and during the hair image blend of these figure layers and the bottom, those edges of regions and bottoms that are changed color attribute are that gradual change is merged, and make the effect of dyeing more natural.
4. path hair dyeing: the operator need at a plurality of points of hair image pickup, connect into the path.Extend out a certain size radius take this paths as the axle center, form the regional area of an appointment in the hair image, the operator get a little describe after, select or own adjustment required color, just easily realizing route is had hair dyed.The mode of color change is: kept the brightness attribute of former hair color, form and aspect, the saturation attributes of color are modified.In the regional area that is modified color attribute hair image and the place that is not modified part and is connected, the effect that color is revised weakens gradually with gradual manner, makes the whole structure after dyeing more natural.
As shown in architecture Fig. 1, the manual beauty treatment in step (13) comprises following two kinds of methods:
1. grind the skin anti-acne: face area is combined with Gaussian Blur algorithm and skin detection algorithm, face image is carried out anti-acne process.
2. skin is cloned: the operator first gets a point by mouse face area on composograph, orientates source point as.Then mouse press drag in, near the facial information source point will be by the complete zone that mouse drags that copies to, and can cover with skin area information preferably the skin area information of other parts like this.
In step (13), light is played up: add the effect of light-illuminating to composograph, as shown in figure 14.
By above-mentioned steps, the operator can design brand-new, beautiful moulding like a cork on the basis of the face image of inputting.
(14) after designing moulding, the stylist can also be by the plane/video teaching that associates with every money hair image, corresponding moulding, the design cycle of study hair image.
