In the present specification, a pattern encoding method is provided, and the present specification simultaneously relates to a pattern encoding apparatus, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.
Fig. 1 shows a flowchart of a pattern encoding method provided in an embodiment of the present specification, which specifically includes the following steps:
step 102: and acquiring a pattern to be coded.
The pattern to be coded may be an icon of an application or a pattern of an object desired to be shared.
Step 104: the method comprises the steps of disassembling a pattern to be coded into a plurality of preset basic patterns, and determining pattern attributes corresponding to the basic patterns contained in the pattern to be coded and first drawing parameters of the pattern attributes.
The pattern is disassembled based on a preset basic pattern, and the basic pattern can be points, line segments, arcs, circles, ellipses and the like.
The graphic attributes corresponding to the basic graphics may include attribute information of each basic graphic and a relative relationship between any two basic graphics, and determining the graphic attributes corresponding to the basic graphics included in the pattern to be encoded may include: and determining the attribute information of each basic graph and the relative relationship between any two basic graphs.
Because the relative relation between the attribute information of each basic graph and the basic graph is easy to determine and has fixed parameters, the method for determining the graph attribute is simplified, and the accuracy is improved.
The attribute information of the basic figures can be length, width, curvature, radius, etc., and the relative relationship between the basic figures can be expressed as distance, included angle, etc. between the basic figures. The first drawing parameter of the graph attribute is a numerical value corresponding to the attribute information and the relative relationship of the basic graph, and is used as a baseline drawing parameter.
Step 106: and adjusting the first drawing parameter of the graphic attribute to construct at least one second drawing parameter of the graphic attribute.
Adjusting the baseline rendering parameters of the graphic attributes to construct at least one second rendering parameter of the graphic attributes comprises:
and modifying the first drawing parameter of the graphic attribute within a predetermined range to form at least one second drawing parameter of the graphic attribute.
The modification within the predetermined range may be, for example, a ratio of a difference between the modified rendering parameter and the baseline rendering parameter to the baseline rendering parameter within a predetermined range, for example, a modification range of the length parameter to the width parameter is within 15%, a modification range of the curvature parameter to the radius parameter is within 25%, a modification range of the distance parameter to the angle parameter is within 20%, the above parameter modification ranges are listed for illustrative purposes only, and are not to be construed as limiting the scope of the present specification.

The mapping table may have n rows (n is greater than or equal to 2), the first row records the mapping relationship between the graphic attribute and the baseline drawing parameter, and the 2 nd to n th rows record the mapping relationship between the graphic attribute and the first adjusted drawing parameter value, i.e., the n-1 th adjusted drawing parameter, and the arrangement of the mapping table is not limited to the above manner.
Fig. 2 is a schematic diagram illustrating an example of a pattern encoding method provided in an embodiment of the present specification.
As shown in part (a) of fig. 2, the pattern to be encoded is formed by combining two basic patterns of a circle and a line segment. After the pattern to be coded is disassembled, the corresponding graphic attributes of the basic graphic contained in the pattern to be coded are A, B, C, D and E, wherein A is the width parameter of the basic line frame; b is the distance between the circular edge and the base line frame; c is a length parameter of the line segment; d is an included angle parameter between the line segment and the horizontal line; and E is the distance between the intersection point of the two line segments and the center of the circle.
At least one of the drawing parameters of A, B, C, D and E is modified within a predetermined range, and the ratio of the difference between the modified drawing parameter and the baseline drawing parameter to the baseline drawing parameter is within the predetermined range, so that the finally formed pattern as shown in part (b) of FIG. 2 does not differ too much from the pattern shown in part (a) of FIG. 2, has visual consistency, and is able to be identified differently.
As shown in part (b) of fig. 2, in the example of the present embodiment, the drawing parameters of the graphic attributes C and E are modified, and the remaining parameters are not changed.
The graphics attributes A, B, C, D and E are mapped with each of the baseline rendering parameters and the modified rendering parameters, respectively, to generate a mapping table.
TABLE 1 mapping table
| Code | A-B-C-D-E |
| 000 | 60-10-15-105-08 |
| 001 | 60-10-13-105-06 |
| 002 | 60-10-14-105-07 |
| … | … |
B. C, D and E are drawn with A as a proportional base line and drawing parameters of other attributes are drawn as the proportion of the drawing parameters of the attribute A, so that the pattern stretching/cutting can be realized with high recognition degree and high anti-interference performance.
The pattern encoding method provided in this embodiment generates a plurality of patterns having a slight difference from one pattern based on the graphic attributes and the drawing parameters of the patterns, and achieves the same effect as the watermark. The pattern coding method provided by the embodiment has no requirement on the pixels of the image, so that the method does not depend on the image resolution, the graphic attribute and the drawing parameter are not changed during screenshot or photographing, the method can be applied to the dynamically changed image, and the parameters are changed in proportion under the condition of pattern stretching/cutting, so that the anti-interference performance is high.

The association request may be a service association request or a user association request, where the service association request carries different service identifiers and the user association request carries different user identifiers.
After the mapping table shown in table 1 is generated, in response to receiving user association requests of different users, user identifications of the different users are associated with the conversion codes to form a user association table. The user identifications of different users correspond to the graphic attributes and different drawing parameters in the mapping table, so that patterns drawn by the different drawing parameters can be distributed to different users.
Or, in response to receiving the different service association request, associating the different service identifier with the conversion code to form a service association table. The service identifications of different users correspond to the graphic attributes and different drawing parameters in the mapping table, so that patterns drawn by the different drawing parameters can be distributed to different services.

The modified pattern drawn with the corresponding drawing parameter 60-10-13-105-06, i.e., the pattern in (b) of fig. 2, is associated with the service as the display pattern of the application icon corresponding to the service.
By applying the coding method provided by the embodiment of the application, the effect of distributing the personalized icon to each service can be realized.
The pattern encoding method according to the present embodiment is further described below by taking a pattern application scenario in which a pattern to be encoded is an object desired to be shared as an example.
