Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only
It is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of method of filter processing, as shown in Figure 1, which comprises
S11, the track for obtaining user's input.
User freely draws a track, such as the curve of an arbitrary shape, can by the touch screen of user equipment into
Row operation, the track that user equipment is got is the set of one group of point.
S12, expansion process is carried out to track.
Assuming that the pixel value of the track got is 1 (i.e. white), track is added to the back that pixel value is 0 (i.e. black)
Jing Tu, the size of Background is identical as the size of color image to be processed, has thus obtained the trajectory diagram of a black and white format.
Using morphologic expansive working, the track in trajectory diagram is handled, it is therefore an objective to make " the line of this single pixel
Item " forms one " region " on the image.The basic principle is that: point to be processed in covering original image is removed with a setting template,
Effect in template is stayed on the diagram.
S14, the region formed after expansion process according to track carry out filter processing to color image to be processed.
By this three figures of grayscale image of trajectory diagram, color image to be processed and color image to be processed after expansion process
Piece is overlapped, so that it may obtain the image that different-effect is handled with previous filter.
In embodiments of the present invention, each pixel meets following relationship in the grayscale image of the color image to be processed
Formula:
Gray=R*0.299+G*0.587+B*0.114,
Wherein, Gray is the pixel value of each pixel in the grayscale image of the color image to be processed, and R, G, B are respectively
The pixel value of tri- Color Channels of RGB of corresponding pixel points in the color image to be processed.
Therefore, the method for filter processing provided in an embodiment of the present invention, the track that can be freely drawn according to user,
The region formed after the track expansion process carries out filter processing to color image to be processed, to be in respectively inside and outside region
Reveal different stylistic effects, the image for obtaining handling different-effect with previous filter can increase filter compared with prior art
The diversity and flexibility of mirror treatment effect, so as to improve user experience.The present invention, which is equivalent to, simultaneously provide the user one
To the approach that picture is created again, the comparison of effect inside and outside the region formed by track drafting wants table to highlight oneself
The information reached, increases the participation of user, and interactivity and interest are stronger.
Preferably for the region formed after the expansion process of track, since intersection is non-black i.e. white inside and outside the region
0-1 variation, it is exactly to switch in visual effect stiffly that such result, which is embodied in,.Smoothly mistake is realized in order to improve visual effect
It crosses, as shown in Fig. 2, the method also includes:
S13, emergence processing is carried out to the edge in the region that track is formed after expansion process.
The basic principle handled of sprouting wings is: using certain point as brightness center, its brightness of outside Uniform attenuation, until brightness value
It is 0, the maximum magnitude of radiation is known as Feather Radius.In embodiments of the present invention, Feather Radius 15.
After the region that the track that user draws is formed after expansion process is handled using emergence, forms one and had
The region at edge is crossed, brightness value is between 0 to 1, and for artwork master, the brightness value of each pixel is exactly the pixel
The pixel value of point.
Accordingly, step S14 at this time are as follows: color image to be processed is filtered in the region formed after being handled according to emergence
Mirror processing.By this three figures of grayscale image for treated the trajectory diagram, color image to be processed and color image to be processed of sprouting wings
Piece is overlapped, so that it may obtain the image that different-effect is handled with previous filter, each pixel meets following in the image
Relational expression:
R '=R*w+Gray* (1-w),
G '=G*w+Gray* (1-w),
B '=B*w+Gray* (1-w),
Wherein, R ', G ', B ' are respectively the pixel value of tri- Color Channels of RGB of each pixel in the effect image,
R, G, B are respectively the pixel value of tri- Color Channels of RGB of corresponding pixel points in the color image to be processed, and w is the rail
The pixel value of corresponding pixel points in mark figure, Gray are the pixel of corresponding pixel points in the grayscale image of the color image to be processed
Value.
