Referring to Fig. 1, the embodiment of the present disclosure provides a kind of method of anamorphose.The method of the anamorphose, including it is as follows
Step：
S101:Extract the key point in image.
The extraction of image key points is detected by characteristic point of the algorithm to image, and will have according to testing result
Representational feature point extraction, which comes out, is used as key point.Many algorithms, such as SURF can be used by extracting the key point in image
Algorithm is not defined the extraction algorithm of image key points herein.
S102：Mapping table is established based on the key point and deformation configuration parameter.
Deformation configuration parameter is configured according to the requirement to anamorphose.By providing visual parameter input
Interface can be configured deformation configuration parameter, then be obtained according to the deformation configuration parameter and key point parameter that are provided with
Before to crucial point deformation and deformed mapping relations.
As an example, visual input interface can be input frame, can be and inputs accordingly in input frame
Numerical value completes setting, is also possible to that pre-set parameter is selected to complete setting, or by the way that adjustable button is arranged,
It completes to be arranged by actuating button.
Before obtaining crucial point deformation and after deformed mapping relations, the pixel except key point can be according to it
With the positional relationship of key point, calculate deformation before and deformed mapping relations, thus before obtaining each pixel point deformation and
Deformed mapping relations deform preceding and deformed mapping table to establish.
S103：Deformation process is carried out to described image based on the mapping table.
In anamorphose, by the position in image before being deformed of image slices vegetarian refreshments after mapping table inquiry deformation,
Then the pixel value at pixel position before deforming in image is written to after deformation at image pixel point position, that is, is realized
The deformation of image.
As an application scenarios of the disclosure, face can be deformed.At this point, carrying out face characteristic on the image
Point extracts, and is equivalent to find corresponding position coordinate of each human face characteristic point in facial image, i.e. positioning feature point.This mistake
Journey needs to carry out based on the corresponding feature of characteristic point.Only obtain the characteristics of image for capableing of clear identification characteristics point, and foundation
This feature carries out appropriate search comparison in the picture, and precise positioning feature point position can be just achieved on the image.
According to another embodiment of the disclosure, step S102 is based on the key point and deformation configuration parameter establishes mapping relations
Table can also include the following steps：
S201：The parameter for obtaining the key point before deforming, obtains the first parameter.
Specifically, the coordinate of key point before anamorphose can be obtained in image coordinate by constructing image coordinate, this
When the first parameter can be the coordinate of key point before anamorphose.
S202：The parameter for obtaining the key point after deforming, obtains the second parameter.
Using the method similar with step S201, the coordinate of key point after obtaining deformation is obtained, and using the coordinate as change
Relevant second parameter of key point after property.
S203：It is calculated based on second parameter and first parameter, obtains mapping relations.
The mapping relations between the first parameter and the second parameter can be calculated using various ways.Fig. 3 gives a kind of meter
Calculate the illustrative methods of mapping relations.As shown in figure 3, input picture is the image before deforming, image, that is, deformed figure is exported
Picture, (x0, y0) indicate that the characteristic point coordinate (for example, first parameter) before mapping, (x, y) indicate that the characteristic point after mapping is sat
It marks (for example, second parameter), MAP (x, y) is mapping table.
The calculating of mapping relations can be carried out using different mapping methods.Divide from the direction of mapping, can use
Two kinds of basic mapping methods：Direct mapping and reverse Mapping.Direct mapping is the image before deformation, before deformation
Corresponding mapping point in image after each point searching deformation in image, and inverse mapping is exactly the opposite.In Direct mapping,
Multiple points in image before deformation may be mapped to the same point after deformation in image, cause to compute repeatedly；Moreover, such as
If fruit is not surjection from the mapping of image after the image to deformation before deformation, it is possible to make certain points after deformation in image
Less than correspondence, cavity is formed.Reverse Mapping does not have these problems, and the disclosure preferably takes reverse Mapping.
S204：Obtain the deformation configuration parameter.

Configuration parameter can be it is pre-set, at this point it is possible to directly read the configuration parameter pre-set.
Alternatively situation, deformation configuration parameter can be the personalization carried out in visualization input interface and set
It sets, reads personal settings parameter, the deformation configuration parameter can be obtained.
S205：Mapping table is established based on the mapping relations and the deformation configuration parameter.
The mapping relations that are obtained based on step 203 and deformation configuration parameter to before being deformed image and deformation after
The each pixel of image mapping table.Specifically, mapping table can be a deformation matrix, which can
To be used to characterize the mapping relations before deformed after image and denaturation between image.
According to another embodiment of the disclosure, which may include：Deformed region, deformation position, deformation class
Type or deformation extent.
These parameters can be inputted or be adjusted by visual mode.For example, can be on visualization interface
Parameter attribute window is set, includes the input dialogue frame of parameter in property window, can choose or input in input dialogue frame
Corresponding parameter, to complete the setting to deformed region, deformation position, deformation type or deformation extent parameter.Wherein deform
Type includes amplification, reduction operation, and deformation extent is the comparative quantity before characterizing anamorphose with change in shape size after deformation, such as
Nose is amplified, 1 times can be amplified, 10 times can also be amplified.
One in addition to deformed region, deformation position, deformation type or deformation extent parameter only deformation configuration parameter is shown
Example property citing, in addition to this it is possible to according to deformation need that other parameters are arranged.
In order to make deformed image seem eurythmy, deformation configuration parameter can be dynamically adjusted.According to the disclosure
Another embodiment, deformation configuration parameter can be according to the key point of target object on image (for example, nose on facial image)
Relative position configuration.
Specifically, the parameters such as region, position of deformation are set according to the relative position of key point, such as key point
Relative position is remote, then biggish range can be set in deformed region, and the relative position such as key point is close, then can be by deformed area
Lesser range is arranged in domain.
For example, for the nose on facial image, if nose is smaller, then the relative position of its key point is also relatively close,
And when as larger such as nose, the relative position of key point is then farther out.When setting deforms configuration parameter, if the parameter of deformed region
It is fixed, then lesser nose is all chosen, and biggish nose, a part is only selected, can seem change in this way
The image of shape not enough coordinates or proportion of deformation distortion.In order to all choose biggish nose, then need according to key point
The parameter of relative position adjustment deformed region.
