Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.

FIG. 1 is a flow diagram illustrating a method of determining similar avatars, according to an exemplary embodiment. The method for determining the similar avatar can be applied to the terminal device or the personal computer, for example, implemented by an application program or software installed on the terminal device or the personal computer. The terminal equipment can be a smart phone, a tablet computer and the like. Referring to fig. 1, the method of determining similar avatar includes:

step 101, generating first head image comparison information of the current user according to the first head image of the current user.

In the present disclosure, the current user is a user about to join a group, or a user who has joined a group and needs to determine whether the same or similar avatar exists in the group. For example, for a user about to join a group, the method provided by the embodiment of the present disclosure is triggered when applying for joining the group. For another example, for a user who has joined a group and needs to determine whether the same or similar avatar exists in the group, a trigger button may be set at a group chat screen or a personal screen of the user in the group, and the user may trigger the method provided by the embodiment of the present disclosure by clicking the trigger button.

In the present disclosure, the first avatar comparison information is generated according to parameters of the first avatar, and is used for characterizing features of the first avatar and determining similarity between the first avatar and a second avatar in a subsequent embodiment. The first head image comparison information may be a first gray value vector of the first head image, or may be a first color value vector or a first luminance value vector of the first head image. The parameters in this embodiment may include a gray value, an RGB color value, and the like of the first avatar. By quantizing the parameters, a matrix corresponding to the first head image after quantization is obtained, and the matrix may be a first gray value vector, a first color value vector, a first luminance value vector, or the like. Namely, the first head image is quantized to obtain the first head image comparison information.

And 102, generating second avatar comparison information corresponding to the second avatar of the at least one other user according to the second avatar of the at least one other user in the group where the current user is located.

The group in the present disclosure is a group to which a current user is about to join, or a group that has already joined. It is understood that a group in the present disclosure generally includes a preset number of users, i.e., a current user and a plurality of other users. For example, a group may include 500 users, the current user and 499 other users. Of course, the group in this disclosure may also include 2 users, i.e., the current user and one other user. The second avatar comparison information in this embodiment is generated according to parameters of the second avatar, and is used to characterize features of the second avatar and to determine similarity between the second avatar and the first avatar in a subsequent embodiment. The parameters in this embodiment may include a gray value, an RGB color value, and the like of the second avatar. In one embodiment, the second avatar comparison information may be a second gray value vector, a second color value vector, or a second luminance value vector of a second avatar of each other user within the group.

It is understood that step 101 and step 102 may be interchanged or performed simultaneously in the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto.

Step 103, determining a similarity value between the first avatar of the current user and the second avatar of at least one other user in the group based on the first avatar comparison information and the second avatar comparison information.

In this embodiment, the first head image comparison information is a first gray value vector or a first color value vector; the second avatar comparison information is a second gray value vector or a second color value vector. In this case, the first avatar comparison information and each of the second avatar comparison information may determine a similarity value, such that at least one similarity value may be determined when there is at least one other user in the group.

Certainly, the first avatar comparison information is a first gray value vector and a first color value vector, the second avatar comparison information is a second gray value vector and a second color value vector, before determining the similarity value, it needs to first determine whether the first avatar comparison information and the second avatar comparison information belong to the same type of vector, for example, if the first avatar comparison information is the first gray value vector, the second avatar comparison information is the second gray value vector, otherwise, the similarity value calculation cannot be performed. It is to be understood that the similarity value is used in this disclosure to characterize the degree of similarity between the first avatar comparison information and the second avatar comparison information.

And 104, if the similarity value greater than or equal to a preset threshold value exists in the similarity values, determining the second head portrait of the other user corresponding to the similarity value greater than or equal to the preset threshold value as the head portrait similar to the first head portrait of the current user.

In this embodiment, the preset threshold is used to represent that the current user and other users in the group can determine that the two avatars are similar or the same. For example, when the similarity value is greater than or equal to the preset threshold, it may be determined that the two avatars are the same when the current user and the other users in the group look at each other, and when the similarity value is less than the preset threshold, it may be determined that the two avatars are different when the current user and the other users in the group look at each other. Therefore, the preset threshold in this embodiment may be set according to a specific scenario, and the embodiment of the present disclosure is not limited.

Therefore, the head portrait similar to the first head portrait of the current user in the group can be found, the same or similar head portrait can be conveniently found by the user, the situation that which user cannot be determined to speak during group chat is avoided, and therefore the experience of the user during group chat is improved.

FIG. 2 is a flow diagram illustrating a method of determining similar avatars, according to another exemplary embodiment. Referring to fig. 2, the method for determining similar head portraits includes:

step 201, generating first head image comparison information of the current user according to the first head image of the current user.

The specific method and principle of step 201 and step 101 are the same, please refer to fig. 1 and related contents of step 101 for detailed description, which is not repeated herein.

Step 202, graying the first head portrait to obtain a first gray image of the first head portrait.

In this embodiment, the first head portrait is grayed to obtain a first grayscale image of the first head portrait. For example, the first head image is grayed, and each pixel in the first head image can be changed to a gray value of 0 to 255, so that a first gray image of the first head image can be obtained.

In an embodiment of the present disclosure, assuming that the first head image includes 9 pixels, graying the first head image to obtain a first grayscale image is:

step 203, converting the first gray image into the first gray value vector, i.e. the first portrait comparison information of the current user.

In this embodiment, the first gray image is converted into a first gray value vector, for example, each row of pixels of the first gray image is sequentially embedded in the gray value vector, and the length of the gray value vector is the product of the length and the width of the first gray image.

Continuing with the example in step 202, converting the first grayscale image in this disclosure to a first grayscale vector is:

A＝[1，231，132；4，22,100；255,200,189]。

in the embodiment of the present disclosure, step 202 and step 203 may be combined, and a process of obtaining the first grayscale image is omitted, that is, the first head portrait is grayed to directly obtain the first grayscale image of the first head portrait. Therefore, the calculation steps can be simplified, and the calculation efficiency can be improved.

Step 204, for each second avatar: and graying the second head portrait to obtain a second gray image of the second head portrait.

In an embodiment of the present disclosure, assuming that each second head portrait includes 9 pixels, graying one of the second head portraits to obtain a second gray image is:

step 205, converting the second gray image into the second gray value vector, i.e. the second avatar comparison information of the user.

Continuing with the example in step 204, converting the second grayscale image in this disclosure to a second grayscale vector is:

B＝[5，204，125；41,88,90；208,155,178]。

in the embodiment of the present disclosure, step 204 and step 205 may be combined, and a process of obtaining the second gray scale image is omitted, that is, the second head portrait is grayed to directly obtain the second gray scale image of the second head portrait. Therefore, the calculation steps can be simplified, and the calculation efficiency can be improved.

It is understood that the combination of

steps

202 and 203 and the combination of

steps

204 and 205 in the embodiment of the present disclosure may be performed in an interchangeable order, or simultaneously.

Step 206, determining a similarity value between the first avatar of the current user and the second avatar of at least one other user in the group based on the first avatar comparison information and the second avatar comparison information.

In one embodiment, for each of the other users in the group, cosine values of the first avatar comparison information and the second avatar comparison information of the second avatar for that each user are determined. And determining a similarity value between the corresponding second head portrait of each user and the first head portrait of the current user based on the cosine value in the embodiment, so as to obtain at least one similarity value.

For example, one other user is selected from the group, and then the cosine values of the first avatar comparison information corresponding to the current user and the second avatar comparison information of the other user are calculated. Taking the first avatar comparison information a and the second avatar comparison information B illustrated in step 101 and step 102 as examples, the cosine values cos < a, B > are:

it can be understood that, as the cosine value cos < a, B > increases, the closer the first avatar comparison information and the second avatar comparison information are, i.e., the more similar the first avatar of the current user and the second avatar of the other user.

Step 207, if there is a similarity value greater than or equal to a preset threshold in the similarity values, determining the second avatar of the user corresponding to the similarity value greater than or equal to the preset threshold as an avatar similar to the first avatar of the current user.

In practical applications, if the similarity value of two avatars exceeds a certain threshold, the user may feel that the two avatars are the same, i.e., the avatars are easily confused. In an embodiment of the present disclosure, a preset threshold is used to determine whether two avatars are similar. Correspondingly, when the similarity value which is greater than or equal to the preset threshold value exists in the at least one similarity value, the second head portrait of the user corresponding to the similarity value which is greater than or equal to the preset threshold value is determined as the head portrait which is similar to the head portrait of the current user. In practical applications, the preset threshold may be set according to specific scenes, for example, when the number of people is large, the preset threshold may be set to be smaller, for example, 0.8, so as to prevent a plurality of similar head portraits from appearing. Or the number of people in the group is small, the preset threshold value can be set to be larger, such as 0.9, so that the user can distinguish the head portrait similarity value from the time scale even if the head portrait similarity value is below 0.9. The present embodiment is not limited thereto, and those skilled in the art can make modifications.

Therefore, according to the embodiment of the disclosure, the first head portrait and the second head portrait are respectively converted into the gray value vectors, and the similarity between the first head portrait and the second head portrait is calculated by using the gray value vectors, so that not only can the calculation amount be reduced, but also the calculation accuracy can be improved, and the head portrait similar to the first head portrait of the current user in the group can be found, so that the user can find the same or similar head portraits conveniently, and the situation that which user can not be determined to speak during group chat is avoided, thereby improving the experience of the user during group chat.

in general, the first head portrait is a color image, each pixel includes three colors of red R, green G and blue B, in this embodiment, the same color in each pixel, for example, red R, green G or blue B, may be provided from the first head portrait, so that a first color image of the same color in one frame may be obtained. Therefore, when the first head portrait can be represented by the first color image, the subsequent calculation amount is reduced, and the calculation efficiency is improved.

The quantized numerical values of the respective colors in this embodiment can be realized by the acquisition method in the related art, and will not be described in detail here.

Step 303, converting the first color image into the first color value vector, i.e. the first portrait comparison information of the current user.

And converting the first color image into the first color value vector, namely the first portrait comparison information of the current user. It can be understood that, the process of converting each pixel in the first color image into the first color value vector may refer to step 203, and will not be described herein again.

In the embodiment of the present disclosure, step 302 and step 303 may be combined, and the process of acquiring the first color image is omitted, that is, the first color image of the first avatar is directly obtained according to the data of the same color of the first avatar. Therefore, the calculation steps can be simplified, and the calculation efficiency can be improved.

Step 304, for each second avatar: extracting the same color in each pixel from the second head portrait to obtain a second color image of the second head portrait; the color extracted from the second avatar is the same as the color extracted from the first avatar.

In an embodiment of the present disclosure, for each second avatar, reference may be made to step 204 for a process of obtaining a second color image of the second avatar according to the second avatar, which is not described herein again.

Step 305, converting the second color image into the second color value vector, i.e. the second avatar comparison information of the other user.

In an embodiment of the present disclosure, step 205 may be referred to in a process of converting the second color image into the second color value vector according to the embodiment, and details are not repeated here.

In the embodiment of the present disclosure, step 304 and step 305 may be combined, and the process of acquiring the second color image is omitted, that is, the second color image of the second avatar is directly obtained according to the data of the same color of the second avatar. Therefore, the calculation steps can be simplified, and the calculation efficiency can be improved.

It is understood that the combination of

steps

302 and 303 and the combination of

steps

304 and 305 in the disclosed embodiment can be performed in an interchangeable order, or simultaneously without limitation.

Step 603, determining a similarity value between the first avatar of the current user and the second avatar of at least one other user in the group based on the first avatar comparison information and the second avatar comparison information.

The specific method and principle of step 603 and step 103 are the same, and please refer to fig. 1 and related contents of step 103 for detailed description, which is not described herein again.

Step 604, if there is a similarity value greater than or equal to a preset threshold in the similarity values, determining the second avatar of the other user corresponding to the similarity value greater than or equal to the preset threshold as an avatar similar to the first avatar of the current user.

The specific method and principle of step 604 and step 104 are the same, and please refer to fig. 1 and the related contents of step 104 for detailed description, which is not repeated herein.

Step 605, responding to a first instruction of a current user, displaying at least one frame of head portrait in a designated gallery; wherein the designated gallery comprises a preset gallery or a historical gallery; the preset image library comprises a plurality of frames of pre-selected head portraits, and the historical image library comprises the head portraits used by the current user.

And 606, responding to a second instruction of the current user on the interactive interface of the designated gallery, and replacing the head portrait of the current user with the head portrait corresponding to the second instruction.

In an application scenario of the present disclosure, as shown in fig. 7(a) -7 (e) (5 figures in total), after a current user joins the group XX-Team, if the current user needs to confirm whether there are other users with the same or similar head portraits within the group XX-Team, the "add" button 701 shown in fig. 7(a) is triggered to obtain the interface shown in fig. 7(b), and then the "add" button 701 becomes the "close" button, and a "head portraits similarity determination" button 702 appears at the bottom of the "close" button 701 (below in fig. 7 (b)). After the "avatar similarity determination" button 702 is triggered, the steps of the method shown in fig. 1 are performed, and when it is determined that an avatar similar to the current user's avatar is similar to the current user's avatar, a bullet box 703 is displayed, which bullet box 703 includes text (e.g., a user who finds a similar or identical avatar, whether to replace the avatar) and a button (e.g., button "yes" and/or button "no"). Then, according to the triggering operation of the current user, whether the head portrait of the current user is replaced is determined, which comprises the following steps:

when the button "no" is triggered, it is not more like an avatar. Alternatively, when the button "yes" is triggered (corresponding to the first instruction), at least one frame of avatar in the designated gallery is displayed in response to the trigger operation, and fig. 7(e) shows a multi-frame image. When the current user selects to trigger one frame of avatar, such as avatar 705 in the middle of fig. 7(e), button yes and/or button no appears in the interactive interface of the designated image, and finally, after the current user selects trigger button yes, the avatar of the current user is replaced with the selected avatar 705. If the current user selects the trigger button "no", the current user may reselect the avatar until the avatar is determined, and after the current user selects the trigger button "yes", the avatar of the current user is replaced with the selected avatar 705.

In this embodiment, the current user can actively replace the head portrait, thereby avoiding the situation that the head portraits are similar or the same, and improving the group chat experience of the user. In practical application, because the hobbies of each user are different, the current user is guided to actively change the head portrait, the participation sense of the current user can be improved, and the group chat experience is improved.
