Fig. 1 is a schematic diagram of one application scenario of a method for forming a two-dimensional code image matrix according to some embodiments of the present disclosure.
As shown in fig. 1, in the application scenario of fig. 1, the server 101 may perform a first matrix operation on the target deformation matrix 102 and the original two-dimensional code image matrix 103, to generate a first special-shaped two-dimensional code image matrix 104. The server 101 may convert the target deformation matrix 102 into a data stream 105. Here, the step of generating the first irregular two-dimensional code image matrix 104 and the step of converting the target deformation matrix 102 into the data stream 105 may be performed simultaneously, regardless of the order. Finally, the server 101 generates a second special-shaped two-dimensional code image matrix 106 according to the first special-shaped two-dimensional code image matrix 104 and the data stream 105.
It is understood that the method for forming the two-dimensional code image matrix may be performed by a terminal device, or may be performed by a server (e.g., the server 101 shown in fig. 1), or may be performed by various software programs. The terminal device may be, among other things, various electronic devices with information processing capabilities including, but not limited to, smartphones, tablet computers, electronic book readers, laptop and desktop computers, and the like. Further, when the execution subject is software, it may be installed in the above-listed electronic device. It may be implemented as a plurality of software or software modules, for example, for providing distributed services, or as a single software or software module. The present invention is not particularly limited herein.
It should be understood that the number of servers in fig. 1 is merely illustrative. There may be any number of servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of some embodiments of a method of generating a two-dimensional code image matrix according to the present disclosure is shown. The method for generating the two-dimensional code image matrix comprises the following steps of:
and step 201, performing a first matrix operation by using a target deformation matrix corresponding to the target shape and an original two-dimensional code image matrix, and generating a first special-shaped two-dimensional code image matrix.
In some embodiments, the execution subject of the method for generating a two-dimensional code image matrix (e.g., the server 101 shown in fig. 1; e.g., the aforementioned terminal device; e.g., software installed in the server and the terminal device) may perform a first matrix operation with the original two-dimensional code image matrix by using the target deformation matrix, so as to generate a first special-shaped two-dimensional code image matrix. Herein, the image matrix generally refers to data used by a computer to express an image. The image is a presentation result seen by the user. In some cases, the image matrix and the image may be considered as essentially identical objects. After the image is converted into a matrix form, the digital image can be analyzed and processed by adopting matrix theory and matrix algorithm.
The target shape described above may generally be a shape or shape profile that is provided or specified by a user. The target deformation matrix generally refers to a matrix form of an image formed by the target shape or a matrix form of an image formed by an outline of the target shape, for example, a matrix obtained by processing such as binarization.
The first matrix operation generally refers to matrix mathematical operation performed on the target deformation matrix and the original two-dimensional code image matrix; in some embodiments, to ensure that matrix mathematical operations (e.g., multiplication operations) are performed, larger matrices may be partitioned or transformed.
In some optional implementations of some embodiments, the original two-dimensional code image matrix is obtained by encoding target information. Conventional two-dimensional code generation methods, such as encoding information into square two-dimensional code images, are well known to those skilled in the art and will not be described herein. The target information is information that needs to be encoded to generate a two-dimensional code image matrix, for example, information such as text and picture.
Step 202, converting the target deformation matrix into a data stream.
In some embodiments, the execution body may convert the target deformation matrix into a data stream (data stream). Wherein the data stream can be restored to the target deformation matrix. The data stream is generally referred to herein as a set of ordered data sequences having bytes with a start point and an end point. Here, the above data stream generally refers to a one-dimensional data stream. The execution body may transform the target deformation matrix into a data stream in a data transformation manner.
In some optional implementations of some embodiments, the execution body may convert the target deformation matrix into an initial data stream. And error correction encoding (e.g., turbo code, etc.) is performed on the initial data stream to generate the data stream. Here, a data stream more resistant to noise and loss of information can be obtained after error correction encoding.
It should be noted that there is no sequence between the step 201 and the step 202; step 201 may be performed before or after step 202, or step 201 may be performed concurrently with step 202.
And 203, generating a second special-shaped two-dimensional code image matrix according to the data stream and the first special-shaped two-dimensional code image matrix.
In some embodiments, the executing body may generate the second irregular two-dimensional code image matrix according to the data stream and the first irregular two-dimensional code image matrix. The outline shape of the second special-shaped two-dimensional code image matrix when being displayed matches the target shape, and the second special-shaped two-dimensional code image matrix comprises the data stream. As an example, the execution subject may append the data stream to the first irregular two-dimensional code image matrix to generate a second irregular two-dimensional code image matrix.
In some embodiments, the visual effects of the first irregular two-dimensional code image matrix and the second irregular two-dimensional code image matrix may be similar when displayed. In some embodiments, the process of adding the data stream to the first shaped two-dimensional code image matrix is a data transformation of a frequency domain angle (for example, the data stream is used to replace partial data of a middle-high frequency region of the first shaped two-dimensional code image matrix when the first shaped two-dimensional code image matrix is changed into the frequency domain matrix), so that the influence on the visual effect is less.
In some optional implementations of some embodiments, the executing body may add the data stream to a color component of the first irregular two-dimensional code image matrix to obtain the second irregular two-dimensional code image matrix.
Here, the execution body may further append a data stream to the color component of the first irregular two-dimensional code image matrix by a discrete cosine transform (DCT, discrete Cosine Transform), a wavelet transform (WT, wavelet transform), or the like. Discrete cosine transform generally refers to a transform related to fourier transform, which is similar to discrete fourier transform (DFT, discrete Fourier Transform).
The color components described above generally refer to gray-scale color components (for example, a numerical range of 0 to 255) in a gray-scale image when the gray-scale image is represented by a two-dimensional array, or three color components of RGB when a color RGB image is represented by a three-dimensional array. The range of values is also 0 to 255 for each color component. The above gray scale image generally refers to an image having only one sampling color per pixel. Such images are typically displayed in gray scale from darkest black to brightest white. When the gradation is expressed by one bit, it is displayed as black and white.
In some optional implementations of some embodiments, the executing body may convert the first irregular two-dimensional code image matrix from a grayscale image matrix to a color image matrix. And then the data stream can be added into the color components of the color image matrix to generate the second special-shaped two-dimensional code image matrix.
As an example, the execution subject may convert the first special-shaped two-dimensional code image matrix into a color image matrix by a "gray level-color conversion method".
In some optional implementations of some embodiments, the execution body may further display a shape selection interface; in response to detecting a user selection operation for at least one target shape on the shape selection interface, a deformation matrix corresponding to the selected target shape is acquired as the target deformation matrix.
Here, the shape selection interface may be an interface composed of at least one shape or shape profile selection schematic. The user selection operation generally refers to a user selection operation of one shape or shape profile among at least one shape or shape profile in the interface. The deformation matrix corresponding to the shape may be a matrix generated in advance according to the shape, or may be a matrix generated in response to a user selection operation.
In some optional implementations of some embodiments, the execution body may further obtain the target shape provided by the user. And generating a corresponding deformation matrix as a target deformation matrix according to the target shape.
As an example, the user-provided target shape may be a regular or irregular shape drawn by the user. The execution body may convert the above-described regular or irregular shaped image into a matrix to obtain a target deformation matrix.
In some optional implementations of some embodiments, the executing entity may further obtain an area specified by the user in the first target image matrix. And determining the target shape according to the specified area.
Here, the first target image matrix refers to a matrix form of an image selected by the user, and may be, for example, a matrix form of a background picture or poster to which the user needs to add the second special-shaped two-dimensional code image. The designated area may be at least one area selected from a plurality of selectable areas in the first target image matrix, or may be manually defined by a user by operating the first target image matrix. As an example, the user may manually define an area directly by an operation and then determine the target shape by analyzing the contour boundary in the area.
In some optional implementations of some embodiments, the executing body may further add the second irregular two-dimensional code image matrix to a first target image matrix, to obtain a second target image matrix including the second irregular two-dimensional code image matrix. The second target image represented by the second target image matrix contains an area matched with the target shape, and the area contains a second special-shaped two-dimensional code image represented by the second special-shaped two-dimensional code image matrix. Here, the second target image generally refers to an image to which a second irregular two-dimensional code image is added. For example, a poster, a background picture, or the like to which the second special-shaped two-dimensional code image is added.
According to the method for generating the two-dimensional code image matrix disclosed by some embodiments of the present disclosure, a target deformation matrix and an original two-dimensional code image matrix are utilized to generate a first special-shaped two-dimensional code image matrix, the target deformation matrix is converted into a data stream, and finally a second special-shaped two-dimensional code image matrix is generated. Thus, the method and the device can generate the customized two-dimensional code image matrix for the user based on the requirement of the user. And the abrupt sense of the two-dimensional code in the integrated background is reduced. Because the second special-shaped two-dimensional code image matrix is matched with the target shape, the two-dimensional code image generated based on different target shapes can be more personalized, and the more personalized two-dimensional code image can be automatically generated by the device based on the target shape determined by the user without manual independent manufacturing. The two-dimensional code image display method is enriched.
With further reference to FIG. 3, a flow 300 of some embodiments of a method of transforming a two-dimensional code image matrix is shown. The process 300 of the method for transforming the two-dimensional code image matrix comprises the following steps:
step 301, extracting a data stream from the color components of the second irregular two-dimensional code image matrix.
In some embodiments, the execution body of the method of transforming the two-dimensional code image matrix (e.g. the server shown in fig. 1; e.g. the aforementioned terminal device; e.g. the software installed in the server and the terminal device) may extract the data stream from the color components of the second special-shaped two-dimensional code image matrix. The extraction of the data stream may be performed by extracting the data stream from the color component using a discrete cosine transform, a wavelet transform, or a related transform thereof.
And 302, matrixing the data stream to obtain a target deformation matrix.
In some embodiments, the execution body may matrix the data stream extracted in step 301 to obtain the target deformation matrix.
In some alternative implementations of some embodiments, the execution body may decode the data stream to obtain an initial data stream. The execution body may then matrix the initial data stream to obtain a target deformation matrix. The initial data stream generally refers to a decoded data stream. The matrixing process generally refers to a process that an executing body processes a data stream in a data transformation manner to obtain a target deformation matrix.
And 303, extracting gray components of the second special-shaped two-dimensional code image matrix to obtain a first special-shaped two-dimensional code image matrix.

In some embodiments, the execution body may perform a second matrix operation on the target deformation matrix and the first irregular two-dimensional code image matrix to obtain an original two-dimensional code image matrix. Here, the second matrix operation may be an inverse operation of the first matrix operation.
In some optional implementations of some embodiments, the executing body may further parse the original two-dimensional code image matrix to obtain target information.
In some optional implementations of some embodiments, the second irregular two-dimensional code image matrix may be obtained by scanning a second target image by the execution subject; the second special-shaped two-dimensional code image matrix provided by the execution subject and obtained after the other subjects scan the second target image can also be obtained by the execution subject.
