[ detailed description ] A
In order to better understand the technical scheme of the invention, the following detailed description of the embodiments of the invention is made with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
An embodiment of the present invention provides an image processing method, which is applicable to any device or software carrier capable of processing an image, such as a mobile phone, a tablet computer or a browser, an application program, and the like, and as shown in fig. 1, the method includes:
101. and acquiring a user identifier.
The user identifier is various information for identifying the user identity, and may include a user name, a digital signature, a unique code assigned by the system, and the like.
102. And acquiring corresponding conversion information according to the user identification.
In order to facilitate subsequent selection of a specified target element in an image element, in the embodiment of the present invention, a conversion information uniquely corresponding to a user identifier is determined by the user identifier, and the conversion information may be a number sequence, an alphabet sequence, a symbol sequence, or a mixture sequence of the foregoing various sequences, or a preset conversion rule, and the embodiment of the present invention is not limited to this.
103. And acquiring an image to be processed.
In the embodiment of the invention, the image to be processed can be an image to be added with various identification information such as a watermark, and the corresponding image storage format can be JPG, PNG, BMP and the like.
104. And acquiring image elements which accord with a specific arrangement mode in the image to be processed.
The specific arrangement is to conform to a specific regular shape, such as a square, a line, a circle, etc.
105. And acquiring a target element from the image element according to the conversion information.
And acquiring a target element from the image elements according to the conversion information, wherein the position relation of the target element in all the image elements corresponds to the conversion information.
This step is implemented in a manner that the relative positional relationship between the image elements may embody a sequence relationship specified by various types of elements or rules carried in the conversion information. For example, if the conversion information is a digital sequence, the relative position relationship between the image elements may embody the information such as the size and sequence of the numbers carried by the digital sequence; if the conversion information is an alphabet sequence, the relative position relationship between the image elements can embody the position, the sequence and other information of the alphabet in the corresponding alphabet; if the conversion information is a symbol sequence, the relative positional relationship between the image elements may reflect information such as the appearance order of the symbols.
106. And labeling the target element.
In the embodiment of the present invention, the annotation is a display status distinguished from other image elements, and may be to adjust the size of the target element; and adjusting the color of the target element. Such as color deepening, color changing or resizing or simultaneous resizing and color, etc., are all alternative implementations.
The process of labeling the target element can be added in an SVG mode, so that the original SVG path of the image to be processed and the SVG path of the standard target element are integrated, and the image added with the user identification can be obtained.
The image processing method provided by the embodiment of the invention converts the identification information corresponding to the user into the image display mode uniquely corresponding to the identification information, and embodies the image display mode in the existing image elements on the image to be processed, which needs to be added with the watermark. Therefore, the identification information of the user is embodied in the image while the definition of the image is not influenced. Compared with the prior art that a larger or more obvious watermark is required, the technical scheme provided by the embodiment of the invention can reduce the influence of the watermark on the picture to a certain extent.
Meanwhile, once a user leaks to the network, the user identification information contained in the picture can be analyzed according to the leaked picture, and therefore the source user of information leakage can be found based on the identification information. The method avoids the discovery and erasure of the watermark for the information leakage to a certain extent because the added watermark is not obvious.
Since the content or format of the user id itself is not necessarily converted into image elements for subsequent annotation, the user id needs to be processed to determine appropriate conversion information. For example, if the user identifier is a true letter sequence, the user identifier satisfying the letter sequence needs to be converted into a number sequence for labeling the subsequent image element, and similarly, if the user identifier satisfying the letter sequence is a true number sequence, the user identifier satisfying the number sequence needs to be converted into a letter sequence for labeling the subsequent image element. Based on this purpose, the embodiment of the present invention provides a corresponding implementation procedure for the conversion of the user identifier, that is, provides a specific implementation procedure of step 102, as shown in fig. 2, including:
1021. and encrypting the user identification by using a specified rule to obtain the conversion information.
The implementation manner of the specified rule can be various and can be selected arbitrarily according to the requirement, such as inserting redundant bits, data confusion, conversion into binary numbers, ACSII code conversion, and the like. The embodiment of the invention has the advantages that the selection on the designated rule is open, different processing modes are allowed to be selected by different equipment or software applications, the flexibility is realized, the privacy is ensured, the selection on the designated rule has no difference between the advantages and the disadvantages in the function, only the original data can be accurately and uniquely represented, but the selection on the designated rule with lower complexity has higher efficiency for the equipment performance and the identification cost.
In order to label the image elements conveniently, the editing is performed based on the existing image elements in the image to be processed. For this purpose, an embodiment of the present invention provides a specific implementation manner related to step 104, as shown in fig. 3, including:
1041. and acquiring points in the image to be processed, which accord with a linear arrangement mode.
The points in line arrangement may include grid lines, mark lines, page lines, and other linear image elements that are formed according to points, circles, squares, and short line segments and arranged according to a certain rule, as shown in fig. 4.
Of course, other image elements with specific arrangement, such as dot matrix, field grid, etc., can be selected in the embodiments of the present invention.
It should be added that, not all the to-be-processed images may have points conforming to the linear arrangement manner, so in the implementation manner provided by the embodiment of the present invention, on the premise of not affecting the display effect of the original image, if there are points conforming to the linear arrangement manner in the to-be-processed image, the points are directly used as the basis for labeling the image elements; if the points in accordance with the linear arrangement mode do not exist in the image to be processed, the points in accordance with the preset linear arrangement mode can be added at the inconspicuous position of the image.
In conjunction with the foregoing, the description of the specific implementation manner of the method for completing the image element standard by using the number sequence in the embodiment of the present invention, that is, the specific implementation manner of step 105, is shown in fig. 5, and includes:
1051. and determining a sorting sequence and a first target element according to the conversion information.
The sorting sequence is a sequence for further improving the safety of the user identifier and facilitating the labeling of the image elements, and can be a sequence regenerated by reversing the front and back sequence of each element in the conversion information, disordering according to a specified sequence or alternatively or compositely using according to specified operation rules, digit-letter replacement, ACSII code conversion and the like.
The first target element is a reference image element in all image elements that may be labeled, and a first point or a random point may be selected from the points that conform to the linear arrangement manner, which is not limited in this embodiment of the present invention.
In addition, it should be added that, in order to facilitate the selection and the criteria of the target element, the above-mentioned sorting sequence is generally a numerical sequence. Of course, other possible forms of representation such as letters or symbols can be used, and the representation is selected according to actual situations.
1052. And determining an image element which is spaced from the first target element by the size of the first number according to the size of the first number in the sorting sequence to serve as a second target element.
1053. Determining an image element which is spaced from a second target element by the size of a second number according to the size of the second number in the sorting sequence to serve as a third target element; and so on to obtain all target elements.
In an embodiment of the present invention, the conversion information may include various expressions, such as a number sequence, a letter sequence, a symbol sequence, and the like. Therefore, the flow of determining the sorting sequence may have a certain difference according to the different expression modes of the conversion information. The determination method of the ranking sequence will be discussed below with reference to specific examples.
In the first case: the information is converted into a sequence of numbers.
At this time, the numbers in the number sequence are sorted according to a specified sorting mode to obtain the sorting sequence, or the numbers in the number sequence are adjusted according to specified multiples to obtain the sorting sequence, or the two are combined. This is beneficial to increase the security of the user identifier and also increases the difficulty of identifying the user identifier by other users.
For example, as shown in fig. 6, if the user id is ABCDE, the corresponding number sequence may be 12345, and the corresponding sorting sequence may be adjusted to 54321 by reverse order processing, or may be expanded by multiples of 2, 4, 6, 8, and 10. For convenience of the following description, the sorting sequence is temporarily set to 54321 here. At this time, if there are 40 points corresponding to the linear arrangement mode, then the 5 th point may be selected as the first target element, at this time, the position of the second target element is the 11 th (5 + 1) point, the position of the third target element is the 16 th (11 +4+ 1) point, the position of the fourth target element is the 20 th (16 +3+ 1) point, the position of the fifth target element is the 23 th (20 +2+ 1) point, and the position of the sixth target element is the 25 th (23 + 1) point. The marked grid lines show the effect as a dashed box shown in fig. 7.
In the second case: converting the information into a sequence of letters.
At this time, the sorting sequence is obtained according to the position relation of each letter in the letter sequence in the alphabet corresponding to the letter sequence.
For example, if the user id is 12345, the corresponding alphabetic sequence may be bcdef, and the corresponding sorting sequence may map bcdef to 23456 according to the alphabetic order of the english alphabet, or may map bcdef to 45678 by shifting the sequence number by a certain amount. For convenience of the subsequent description, the sorting sequence is temporarily set to 23456. At this time, if there are 40 points corresponding to the linear arrangement, then the 3 rd point can be selected as the first target element, at this time, the position of the second target element is the 6 th (3 +2+ 1) point, the position of the third target element is the 10 th (6 +3+ 1) point, the position of the fourth target element is the 15 th (10 +4+ 1) point, the position of the fifth target element is the 21 th (15 +5+ 1) point, and the position of the sixth target element is the 27 th (21 +5+ 1) point. The selection and example of the target element in this case is similar to the first case, and reference is also made to the principles shown in fig. 6 and 7.
In the third case: the information is converted into a sequence of symbols.
For example, if the user id is 12345, the corresponding symbol sequence may be "; < = is one time greater? ", the corresponding sorting sequence may be mapped to 59, 60, 61, 62, 63 by the ACSII code value, or the sequence number may be shifted by a certain offset to be"; < = is it? "map to 60, 61, 62, 63, 64. For convenience of the subsequent description, the sorting sequence is herein temporarily set to 60, 61, 62, 63, 64. At this time, if there are 80 points corresponding to the linear arrangement mode, then the 1 st point may be selected as the first target element, at this time, the position of the second target element is the 62 (60 + 1) th point, the position of the third target element is the 124 (62 +61+ 1) th point, the position of the fourth target element is the 187 (124 +62+ 1) th point, the position of the fifth target element is the 251 (187 +63+ 1) th point, and the position of the sixth target element is the 316 (251 +64+ 1) th point. The selection and example of the target element in this case is similar to the first case, and reference is also made to the principles shown in fig. 6 and 7.
It should be noted that the above generation results and generation manners of the number sequence, the letter sequence and the symbol sequence are merely examples, and may be freely configured and generated according to actual situations, and the embodiment of the present invention is not limited to this.
In addition, in order to solve the problem of how to recognize the user identifier in the image including the labeled image element, an embodiment of the present invention further provides an image processing method, as shown in fig. 8, including:
201. and acquiring an image to be processed.
The image to be processed is the image obtained after the step 106 is executed.
202. And acquiring image elements which accord with a specific arrangement mode in the image to be processed.
The image elements according to the specific arrangement mentioned herein correspond to the image elements mentioned in step 104, because the labeled image elements are represented in the image elements according to the specific arrangement in the image to be processed, it needs to be searched in the image to be processed.
203. And determining the marked target elements from the image elements which accord with the specific arrangement mode.
204. And determining the user identification according to the marked target element.
Corresponding to the foregoing step 1041, a specific implementation manner of the step 202 is to obtain points in the to-be-processed image, which conform to the linear arrangement manner.
Corresponding to the foregoing step 106, the specific implementation manner of step 203 requires that image elements with specific specification and/or specific color are determined as labeled target elements from image elements conforming to a specific arrangement manner.

The image processing device provided by the embodiment of the invention converts the identification information corresponding to the user into the image display mode uniquely corresponding to the identification information, and reflects the image display mode in the existing image elements on the image to be processed, which need to be added with the watermark. Therefore, the identification information of the user is embodied in the image while the definition of the image is not influenced. Compared with the prior art that a larger or more obvious watermark is required, the technical scheme provided by the embodiment of the invention can reduce the influence of the watermark on the picture to a certain extent.
