In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
FIG. 3 is a flowchart illustrating a method for generating a cloud representation of character words according to an embodiment of the present invention.
As shown in fig. 3, in step S31, the input picture is processed by the color-lead method to obtain a color-lead effect picture.
As shown in fig. 3, in step S32, the input text is processed using a preset lexicon, which includes a plurality of words, to generate a sorted document of words.
As shown in fig. 3, in step S33, words are filled in the colored-plumb effect picture according to the sorted documents of the words, so as to obtain a character word cloud image.
The method comprises the steps of carrying out colored-leaded processing on an input picture to enable the picture to become a colored-leaded effect picture, filling vocabularies into the colored-leaded effect picture according to the sequencing documents of the vocabularies, and finally obtaining the character word cloud portrait with high accuracy and high generation speed.
In the embodiment of the present invention, before processing the input picture, the method further includes:
judging whether the format of the input picture meets the preset format requirement, if so, continuing to step S31, namely processing the input picture in a colored lead mode; if the format of the input picture does not meet the preset format requirement, a new picture is input again, wherein the preset format requirement comprises, but is not limited to, bitmaps such as PNG (portable network generator), JPG (Java Web page) and the like, and the preset format requirement on the picture can be changed according to the requirement in the actual use process.
In the embodiment of the present invention, fig. 4 shows a flowchart of step S31 in the embodiment of the present invention, that is, the step S31 of processing the input picture in the color-lead manner includes the following steps:
as shown in fig. 4, in step S41, the input picture is converted into a black and white picture, the input picture is as shown in fig. 1, and fig. 5 shows an effect of converting the picture shown in fig. 1 into a black and white picture in the embodiment of the present invention.
As shown in fig. 4, in step S42, a color-lead effect picture is obtained by performing a color-lead process on the black-and-white picture, and fig. 6 shows an effect picture after the color-lead process is performed on the black-and-white picture shown in fig. 5 in the embodiment of the present invention.
After the black-and-white processing in step S41, the black-and-white contrast becomes more obvious after the processing into a black-and-white picture, and then the color-rendering processing in step S42, it should be noted that in step S42, only the regions other than white are color-rendered, and the white regions remain white.
In the embodiment of the present invention, fig. 7 shows a flowchart of step S32 in the embodiment of the present invention, that is, step S32 processes the input text with a preset lexicon, and generating a ranked document of vocabularies includes the following steps:
as shown in fig. 7, in step S71, stop words including punctuation, emoticons, prepositions, and conjunctions are removed from the input text. The input text is derived from files containing words in a preset lexicon, the content of the files is generally related description of characters in the pictures, and the source of the files is not limited and can comprise articles screened from a network or introductory articles in enterprises and the like. The preset word bank is generally formed by adding key words meeting requirements, such as industry common words, on the basis of mass words according to requirements, so that the words in the preset word bank are richer than the mass words, the industry characteristics can be better embodied, and the description of characters in the pictures is more appropriate.
As shown in fig. 7, in step S72, the word frequency and the weight of each vocabulary in the preset lexicon are calculated by using the preset lexicon. The word frequency of a vocabulary is used for representing the number of times of the occurrence of the vocabulary, and the weight of the vocabulary is used for representing the weight of the vocabulary in the file dimension, specifically, the weight calculation of the vocabulary can adopt the following method:
firstly, counting the number of files containing vocabularies; secondly, the weight of the vocabulary is calculated according to the number of the files containing the vocabulary and the number of the total files, the number of the total files can be divided by the number of the files containing the vocabulary, the obtained quotient is subjected to logarithm taking, and the obtained numerical value is the weight of the vocabulary.
As shown in fig. 7, in step S73, a ranking reference value of the vocabulary is calculated according to the word frequency and the weight of the vocabulary, and specifically, the ranking reference value of the vocabulary may be the product of the word frequency and the weight of the vocabulary.
As shown in fig. 7, in step S74, the vocabulary is sorted according to the sorting reference value of the vocabulary to obtain the sorted documents of the vocabulary, and fig. 8 is a schematic diagram of the sorted documents of the vocabulary in the embodiment of the present invention, wherein the number behind the vocabulary is the sorting reference value of the vocabulary.
In the embodiment of the present invention, step S33 is to fill the vocabulary into the colored-plumbum effect picture according to the sorted documents of the vocabulary, and determine the font size of the filled vocabulary according to the size of the sorted reference value of the vocabulary.
In the prior art, the word frequency is often used as the basis of the font size in the process of filling words into a picture to generate an image, and the product of the word frequency and the word weight is used as the basis of the font size in the embodiment of the invention, so that the association degree of the words and the task in the picture can be embodied from multiple dimensions, and the accuracy of the obtained character word cloud image is higher.
Fig. 9 shows an effect diagram of a person word cloud image finally obtained in the embodiment of the present invention. As can be seen from fig. 9, since the black change and the color-lead treatment are performed on the picture, the white area is not filled when the words are filled into the color-lead effect picture, and thus the obtained character word cloud picture is beautiful and rich in color.
In summary, in the method for generating the character word cloud image provided in the embodiment of the present invention, the input picture is processed in a color-lead manner, and the white area is not filled, so that the obtained character word cloud image is beautiful and rich in color. The input text is processed by utilizing the preset word bank, so that the inserted words are more appropriate to the description of the characters in the picture, the association degree is higher, and the accuracy of the portrait can be ensured. The automatic filling process is fast, the period of generating the portrait word cloud portrait is shortened, the portrait word cloud portrait can be rapidly given according to the changes of the input text and the input picture, and the change of data can be rapidly reflected in real time.
