The above-described implementations are described in detail below with reference to specific embodiments and the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a picture adding method, where the picture adding method may be applied to a picture adding apparatus, and the picture adding method may include: S101-S104:
s101, under the condition that a first input of a user is received, the picture adding device responds to the first input, determines keywords of an edited text, and determines M pictures to be added corresponding to the keywords.
Wherein M is an integer greater than 0.
When a user wants to add a cover picture to an edited text, the user may perform a first input to the picture adding apparatus, for example, click and input a first control in a first page of the picture adding apparatus, and after receiving the first input, the picture adding apparatus may respond to the first input by determining a keyword of the edited text first, and then determining M pictures to be added corresponding to the keyword according to the determined keyword.
Optionally, the picture adding apparatus determines that the keywords of the edited text may include at least one of: receiving a keyword input by a user; and determining high-frequency words in the edited text, and determining a first number of high-frequency words as the key words according to the frequency of occurrence.
Specifically, one way is: the image adding device may display a keyword input page in response to the first input after receiving the first input, and the user may input a keyword to be added in the keyword input page, so that the image adding device determines the keyword of the edited text; the other mode is as follows: the picture adding device may determine, in response to the first input, high-frequency words in the edited text by traversing the edited text after receiving the first input, for example, a word whose occurrence number exceeds 5 times may be determined as a high-frequency word, so that the picture adding device determines keywords of the edited text; another way is: the image adding device can respond to the first input after receiving the first input, firstly receives keywords input by a user in a keyword input page, and can add new keywords automatically in a text traversing and editing mode if the number of the keywords input by the user is less than a preset number value.
Optionally, the image adding device may determine, in the preset image search system, M images to be added corresponding to the keyword according to the determined keyword. The preset picture search system may include at least one picture search engine.
It should be noted that the preset image search system needs to determine the user identity according to the predetermined signature information, and may perform the search operation when the signature information input by the user matches. Thus, the safety of the operation can be improved.
Optionally, the picture adding device may determine a time range of the picture searched in the preset picture searching system according to a text type of the edit text input by the user. For example, if the text type of the edited text is a current comment or a headline type, a picture of the latest month is acquired, that is, the start time beginTime is a time one month ago, the end time endTime is a current time, and the times are all in unix timestamp format. If the picture is not the current comment or the headline type, the picture within one year is acquired, beginTime is the time one year ago, endTime is the current time, and the format of unix timemap is also adopted.
S102, the picture adding device displays N pictures to be added in the M pictures to be added according to the relevance.
Optionally, after the image adding device determines M images to be added corresponding to the keyword, the size of M and a first threshold may also be determined, if M is greater than the first threshold, at least one high-frequency word is added as the keyword according to the frequency of occurrence until K images to be added smaller than or equal to the first threshold are obtained; then, displaying N pictures to be added in the K pictures to be added according to the relevance; wherein M is greater than or equal to K, K is greater than or equal to N, and K is an integer greater than 0. Thus, the picture range determined by the picture adding device can be further reduced, and the relevance of the pictures is improved.
The image adding device can enable the preset image searching system to return N images to be added with highest relevance and sorted according to the heat degree according to the interface setting, and after the interface returns the N images to be added, the image adding device can display the N images to be added in a list form. The N pictures to be added can be displayed in a list in a form of width limit 480 equal-ratio scaling, and after a user clicks and inputs any one picture, the picture adding device can restore the original size of the picture so as to facilitate the user to review.
S103, under the condition that second input of a user on a first picture in the N pictures to be added is received, the picture adding device responds to the second input and cuts the first picture according to preset size information to obtain a second picture.
Wherein N is an integer greater than 0, and M is greater than or equal to N.
Optionally, after the first picture is determined, the picture adding device may adjust the aspect ratio of the first picture to the aspect ratio corresponding to the preset size information, so as to obtain a third picture.
For example, the preset size information includes 1200 × 462, 365 × 259 and 800 × 309, i.e., the first picture needs to be adjusted to the three sizes respectively. The picture adding device may first save the first picture locally, determine the width and height of the first picture by using a picture address (gettimezise), compare the aspect ratio of the first picture with the aspect ratio of 1200 × 462, 365 × 259 and 800 × 309, respectively, scale the height of the first picture to a desired height if the aspect ratio of the first picture is large, and perform width adaptive processing, or scale the width of the first picture to a desired width if the aspect ratio of the first picture is small, and perform height adaptive processing, thereby obtaining a third picture.
Optionally, the picture adding device may perform clipping processing on the third picture according to pixel differences of pixel points in the third picture, so as to obtain a second picture with a preset size. The image adding device may perform a first operation on each pixel point in the third image, thereby obtaining color difference values of all the pixel points. The first operation may include: determining absolute color difference between a target pixel point and an adjacent pixel point according to the three primary colors of the pixels, and determining the color difference value of the target pixel point according to the absolute color difference, wherein the target pixel point is any one pixel point in the third picture; cutting continuous pixel points of which the color difference values are smaller than a second threshold value in the edge area of the third picture to obtain a fourth picture; determining a pixel average point of the fourth picture; and extending the pixel average point to the periphery to obtain a second picture with a preset size.
Specifically, the picture adding device may determine each pixel point in the third picture, obtain and store pixel information of the third picture through a picture path (macrocreatefrom jpeg), and then determine each pixel according to the pixel informationThe three primary colors of the pixels of the dot. And then, respectively carrying out first operation on the upper pixel point, the lower pixel point, the left pixel point and the right pixel point of the target pixel point to obtain four absolute color difference values of the target pixel point, and then carrying out second operation on the four absolute color difference values of the target pixel point to obtain a color difference value of the target pixel point, so that the color difference value of each pixel point in a third picture is obtained. Wherein the first operation is according to the formula
Determining four absolute color difference values, x, of a target pixel point1、y1And z1Three primary colors, x, of the target pixel point2、y2And z2Three primary colors of any one of the upper, lower, left and right pixels of the target pixel point are shown, and F is an absolute color difference value. The second operation is according to the formula
Determining the color difference value of the target pixel point, F1、F2、F3And F4The absolute color difference values of the upper, lower, left and right pixels of the target pixel point are respectively, and H is the color difference value. Further, the image adding device may perform clipping processing on continuous pixels of which the color difference value is smaller than a second threshold value in an edge region of the third image to obtain a fourth image, where the edge region is an annular region having a preset distance from an edge line of the third image. Then, the picture adding device can add the picture through a formula
Determining the average pixel point of the fourth picture, wherein n is the total number of pixel points and xiThe color difference value of the ith pixel point is obtained; after the pixel average point is obtained, the second picture can be extended to the periphery by taking the pixel average point as the center, and the second picture with the preset size can be obtained by cutting.
It should be noted that if the extension distance in one direction exceeds the edge line of the first picture, the remaining dimension may be extended in the opposite direction.
And S104, the picture adding device displays a second picture at a preset position.
The preset position is a position for displaying a cover picture.
In the embodiment of the invention, under the trigger of the first input of the user, M pictures to be added can be determined according to the determined key words, N pictures to be added with highest relevance in the M pictures to be added are displayed, the user can select one picture from the N pictures to be added according to personal desire, and the cutting operation of the picture is triggered, so that the picture with the preset size is obtained.
