The method for determining a target theme provided by this embodiment first determines a plurality of to-be-selected topics that are closer to the target wallpaper image according to the similarity between the selected theme and the target wallpaper image, and then, the user determines from the plurality of selected topics. Among the selected topics that are closer to the target wallpaper image, one candidate theme is selected as the target theme, and the final target theme satisfies the user's individual needs to a certain extent, and at the same time, the user's selection range is narrowed, and the user selection can be saved. The time spent on the target topic.

In the above embodiment, according to the element information of the target wallpaper picture and the element information of the candidate theme, The similarity between the target wallpaper image and the to-be-selected theme may include the following two application scenarios:

(1) The element information includes a scene of any one of the subject image type information, the attribute information, and the subject image content information of the picture;

If the prime information is the main image type information of the image, the similarity between the two image types is determined in advance, and the similarity between the main image type information of the target wallpaper image and the main image type information of the selected theme is directly queried as the target wallpaper. The similarity between the picture and the subject to be selected. For example, the subject image type of the target wallpaper image is a pet class, and the subject image type of the candidate theme is also a pet class, and the similarity between the subject image type information of the target wallpaper image and the subject image type information of the candidate theme is considered to be relatively high. .

If the prime information is attribute information (for example, time, place), it is assumed that the approximate time of the natural environment included in the subject image and the approximate time of the natural environment included in the target wallpaper image are calculated, and the time corresponding to the target wallpaper image and the candidate theme are calculated. The difference between the corresponding times, the larger the time difference, the smaller the similarity between the two, and the smaller the time difference, the greater the similarity between the two. For example, the time corresponding to the target wallpaper image is spring, and the time corresponding to the selected theme is autumn, the similarity between the two is relatively small.

Similarly, if the attribute information is a location, the geographic distance between the location coordinates of the location of the natural environment included in the target wallpaper image and the location coordinates of the location of the natural environment included in the theme to be selected is calculated. The smaller the similarity, the smaller the geographical distance and the greater the similarity between the two.

If the element information is the subject image content information, the similarity between the subject image content of the target wallpaper picture and the subject image content of the subject to be selected is calculated. The similarity can be expressed by the distance between images (for example, Euclidean distance, cosine distance), where the smaller the Euclidean distance, the greater the similarity between the two images; the larger the cosine distance, the two images The greater the similarity between the two.

(2) The element information includes a scene of any combination of the subject image type information of the picture, the attribute information, and the subject image content information;

S131. Acquire a weight coefficient corresponding to each element information.

In an embodiment of the present invention, the weight coefficient corresponding to the element information may be set according to the degree of influence of the element information on the similarity. For example, the factor that has the greatest influence on the similarity is the subject image content information of the picture, followed by the picture. The subject image type information is again the attribute information of the picture.

S132. Calculate a similarity between the target wallpaper image and the corresponding element information of the candidate theme.

For example, if the element information includes the subject image content information and the attribute information, the similarity between the subject image content information of the target wallpaper image and the subject image content information of the candidate theme is respectively calculated, and the attribute information and the object of the target wallpaper image are calculated. Select the similarity between the attribute information of the topic.

S133. Obtain a similarity between the target wallpaper image and the candidate theme according to a similarity between the target wallpaper image and the corresponding element information of the candidate theme, and a weight coefficient corresponding to the element information.

For example, the element information includes the subject image type information and the subject image content information, assuming that the similarity of the subject image type information between the target wallpaper image and the subject to be selected is d ₁ , the subject image content between the target wallpaper image and the subject to be selected The similarity of the information is d ₂ ; moreover, assuming that the weight coefficient corresponding to the subject image type information is 0.3 and the weight coefficient corresponding to the subject image content information is 0.7, the similarity d between the target wallpaper image and the candidate subject is as in Formula 1. Shown as follows:

d = 0.3 × d ₁ + 0.7 × d ₂ (Formula 1)

The method for obtaining the similarity between the candidate theme and the target wallpaper image provided by this embodiment takes into account that the degree of influence of the different element information on the similarity is different, and the degree of influence on the similarity is set according to different element information. The weight coefficient, according to the similarity between the target wallpaper image and the corresponding element information of the candidate theme, and the weight coefficient corresponding to the element information, finally obtain the similarity between the target wallpaper image and the candidate theme. The similarity between the target wallpaper image calculated by this method and the subject to be selected is more accurate, and further, the target theme determined according to the similarity between the target wallpaper image and the candidate theme is matched with the target wallpaper image. Higher degrees.

Referring to FIG. 4, a schematic flowchart of another method for replacing a theme of a smart terminal according to an embodiment of the present invention is shown. The method may further include the following steps on the basis of the embodiment shown in FIG. 1 :

After executing S150, executing S210, the smart terminal uploads the topic information of the target topic to the server, so that the server stores the topic information of the target topic.

The topic information may include information such as topic type, topic name, topic details, and the like.
