It in the embodiment of the present application, can be every prefixed time interval, such as every 2 seconds, i.e., within this 2 seconds
The written handwriting formed carries out the detection of breakpoint, is handled by this kind, can realize and detect lettering pen in real time as far as possible
Breakpoint in mark, to carry out subsequent breakpoint filling so that written handwriting keeps coherent, promotes user experience.
In this step, reference writing is determined according in preset condition written handwriting shown on touch control face plates first
Breakpoint, it will be appreciated by persons skilled in the art that written handwriting described herein can be above-mentioned described, when current
The written handwriting formed in first 2 seconds carved.
In an optional realization method, the connection number of each pixel on written handwriting can be calculated, specifically,
The connection number of pixel can be calculated by following formula (one)：
In above-mentioned formula (one), NCRepresent the connection number of pixel, f (xk) represent pixel xkPixel value, k represent 8

In the embodiment of the present application, if being 1 by the connection number that above-mentioned formula (one) is calculated, the picture can be determined
Vegetarian refreshments is breakpoint.But in view of in practical applications, it is originally just incoherent that user may also draw some on touch control face plates
Written handwriting for example, as shown in figure 4, another example of the written handwriting shown for touch control face plates, has dotted line in the Fig. 4
Frame as described above, connects number by calculating, then can the endpoint of phantom line segments in dotted line frame be also detected as breakpoint, such as Fig. 4
In the part elected of border circular areas institute frame, and this part of breakpoint is not due to CPU and does not receive location information, and
The person's handwriting breakpoint gone out shown by display, but person's handwriting end point, based on this, in the embodiment of the present application, only walk this
Reference writing breakpoint is regarded as according to the breakpoint that preset condition is determined in rapid 201, subsequently, also needs to carry out reference writing breakpoint
Further detection, that is, perform step 202.
Step 202：Determine whether occur to represent that touch-control body leaves at the touch location corresponding to reference writing breakpoint
The touch control operation of touch control face plates.
By foregoing description it is found that user can touch by touch-control body, such as when finger, stylus touch touch control face plates
It touches and written handwriting is generated on position, then each pixel all corresponds to a touch location on written handwriting.
In the embodiment of the present application, it during user carries out writing operation by touch control face plates, can detect in real time
Whether occur at touch location for representing that touch-control body leaves the touch control operation of touch control face plates, if being detected at a certain touch location
To the touch control operation, then the mark for representing to occur at the touch location touch control operation can be set for the touch location.
It subsequently, then can be by determining whether the corresponding touch location of reference writing breakpoint is corresponding with the mark, to determine that this refers to pen
Whether occur to represent that touch-control body leaves the touch control operation of touch control face plates at the corresponding touch location of mark breakpoint.
Specifically, if the corresponding touch location of reference writing breakpoint is corresponding with above-mentioned mark, the touch position can be determined
It puts place and above-mentioned touch control operation occurs, if the corresponding touch location of reference writing breakpoint is not corresponding with above-mentioned mark, can determine
Above-mentioned touch control operation does not occur at the touch location.
Step 203：If the touch control operation does not occur at the touch location corresponding to reference writing breakpoint, this is referred into pen
Mark breakpoint is determined as true person's handwriting breakpoint.
In the embodiment of the present application, the practical application scene of writing operation, user are carried out by touch control face plates with reference to user
When drawing coherent written handwriting, touch-control body will not leave touch control face plates, when touch-control body leaves touch control face plates, then it represents that
Writing stops (or termination), and the breakpoint formed at this time is also just person's handwriting end point, not person's handwriting breakpoint.Based on this, in this step
In rapid, however, it is determined that do not occur to represent that touch-control body leaves touching for touch control face plates at the touch location corresponding to reference writing breakpoint
The reference writing breakpoint, then can be determined as true person's handwriting breakpoint by control operation, correspondingly, if it is determined that reference writing breakpoint institute is right
Occur at the touch location answered for representing that touch-control body leaves the touch control operation of touch control face plates, then it can be by the reference writing breakpoint
It is determined as person's handwriting end point.
Step 204：The true person's handwriting breakpoint is filled using preset algorithm.
By performing above-mentioned steps 201 to step 203, multiple true pens may be detected during a breaking point detection
Mark breakpoint, then, in the step 204, can breakpoint filling be carried out to written handwriting according to multiple true person's handwriting breakpoint.
In an optional realization method, ant group algorithm may be used and carry out breakpoint filling, specifically, by multiple true
The set that person's handwriting breakpoint is formed arbitrarily selects a breakpoint as the first breakpoint as breakpoint set in the breakpoint set,
Later, using ant group algorithm, the path between another breakpoint in first breakpoint and the breakpoint set is determined, then, according to pre-
If writing parameter the path is filled, and first breakpoint and another breakpoint are deleted in breakpoint set.
Subsequently, the above process is continued to execute for updated breakpoint set, until break point set is combined into empty set.
In the foregoing description, writing parameter can include the information such as color, thickness, the type of paintbrush, also, the writing is joined
Number can be that touch control face plates are set as write mode in user, be recorded before carrying out writing operation, so that filling part
Divide and be consistent with other written handwritings, avoid bringing visual difference sense to user, promote user experience.
It is as follows, ant group algorithm is briefly described：
The basic principle of ant group algorithm is that ant discharges a kind of chemistry for being called pheromones during search of food
Substance, if there is more ant selects same paths, then the pheromones on the path can be built up, these pheromones meetings
Follow-up ant is made a kind of positive feedback mechanism to be formed, with this path of larger probability selection so as to quickly find optimal solution.
Based on the basic principle of above-mentioned described ant group algorithm, in the embodiment of the present application, for above-mentioned first breakpoint,
M ant is placed on the breakpoint, wherein m is the quantity of other breakpoints in addition to the first breakpoint in breakpoint set, wherein, every
Ant selects path according to following formula (two) and formula (three)：
In above-mentioned formula (two) and formula (three), τjFor the pheromone concentration at pixel j, ηijFor pixel i and pixel j it
Between heuristic guidance function, α and β are respectively to find in path process, the pheromones accumulated and heuristic guiding letter
Several impact factors to Path selection, N8For the feasible path of ant, i.e. pixel Xi8 neighborhoods, q is uniformly divided in [0,1] section
The random function of cloth, q0It is a parameter (0≤q0≤ 1), the size of q0 is determined using between priori and exploration path
Relative importance.
With the movement of ant, the pheromone concentration of each pixel number will change, specifically, in one cycle,
The pheromone concentration of pixel j is adjusted according to equation below (four)：
τj(new)=τj(old)(1-ρ)+ΔτjFormula (four)
In above-mentioned formula four, ρ be the attenuation coefficient of pheromone concentration at any time, Δ τjRepresent pixel j in this cycle
Pheromone concentration incrementss.
For a wherein ant, the next pixel walked according to above-mentioned formula (two) to formula (four) calculating ant
Point, and retain the walking path of ant stops walking rule (refer to described below, be not described further first herein) when meeting ant
When, which stops walking, obtains a paths, so as to based on this process, obtain another in the first breakpoint to breakpoint set
The path of one breakpoint.
Later, it in all effective paths (refer to described below, be not described further first herein), selects comprising pixel
Point number is minimum namely shortest path, as the optimal path that current iteration generates, and is compared with former optimal path,
If the optimal path that current iteration generates is more excellent, optimal path is updated, otherwise, the amount of fresh information element, by the process,
Shortest path can then be obtained.
The above-mentioned ant being previously mentioned stops walking rule and includes：
(1) setting longest path limits.If the path length that ant during path finding, is passed by is more than setting value
Lifespan, then ant stops walking, and identifies CI_FAIL for this path setting searched out, that is, finds failure, the path
In vain.
(2) when a breakpoint being set as the first breakpoint, by the edge that the edge labelling where it is breakpoint itself, work as ant
When walking to the pixel at these edges, ant also stops walking, and the path setting mark CI_FAIL searched out for this,
Failure is found, the path is invalid.
(3) when ant goes to former marginal point (other edges for removing breakpoint own edges), then ant stops walking, and is
This path searched out setting mark CI_INSIDE, the i.e. path are connected to inside edge, and the path is effective.
(4) when ant goes to another breakpoint, then ant stops walking, and the path setting mark searched out for this
CI_END, is attached to another breakpoint, that is, finds successfully, and the path is effective.
Correspondingly, above-mentioned described " effective path " includes being identified with the path of CI_INSIDE and CI_END.
Foregoing description only briefly describes the application of ant group algorithm in the embodiment of the present application, as not to the utmost it is detailed it
Place, those skilled in the art may refer to description of the prior art.
