The steps 701, 702-704 are the same as or substantially the same as the corresponding steps shown in FIG. 6, and therefore are not described herein again, and are included herein by reference.

Wherein, in step 705, the generating device 1 performs pre-processing on the hand-drawn graphics to obtain a pre-processed hand-drawn graphics. Specifically, in step 705, the generating device 1 performs preprocessing on the hand-drawn graphics acquired in step 701, such as graphics enhancement processing, denoising, graphics sharpening, etc., to obtain the pre-processed hand-drawn graphics.

Preferably, step 705 can also include sub-step 7051 (not shown), sub-step 7052 (not shown), and sub-step 7053 (not shown). In sub-step 7051, the generating device 1 implements enhancement processing of the hand-drawn graphics by graphical transformation; in sub-step 7052, the generating device 1 performs smoothing or filtering of the hand-drawn graphics by removing noise from the graphics, thereby contributing to improvement of image quality. And facilitating the extraction of the object feature; in sub-step 7053, the generating device 1 implements edge sharpening processing on the hand-drawn graphic by graphic sharpening. For example, when the hand-drawn graphic input by the user is a heart shape, if it is accidentally placed a dot next to the drawn heart shape, the figure The shape smoothing unit can remove the extra points, help to remove noise and repair the graphics; the graphic edge processing unit helps to accurately recognize the corners of the heart, and the high fidelity restores the user's hand-drawn graphics.

Here, after the generating device 1 acquires the hand-drawn graphics input by the user in step 701, the pre-processing of step 705 is performed first, and then the graphic feature recognition is performed on the pre-processed hand-drawn graphics, thereby improving the accuracy of the graphic feature recognition. The generated facial text is more closely matched with the hand-drawn graphics input by the user, further enhancing the user experience.

Figure 8 illustrates a flow chart of a method for generating face text in accordance with yet another preferred embodiment of the present invention. Specifically, in step 801, the generating device 1 acquires a hand-drawn graphic input by the user; in step 802, the generating device 1 recognizes the graphic feature of the hand-drawn graphic; in step 803, the generating device 1 determines that the graphic feature is Corresponding one or more filling elements; in step 806, the generating means 1 determines to fill the element density of the hand-drawn graphics with the filling elements; in step 804, the generating means 1 according to the graphic features, The element density is filled in the hand-drawn graphic with the one or more filling elements, and the corresponding facial characters are generated for the upper screen. The steps 801-803 are the same as or substantially the same as the corresponding steps in FIG. 6, and therefore are not described herein again, and are included herein by reference.

Wherein, in step 806, the generating means 1 determines to fill the element density of the hand-drawn graphic with the filling element. Specifically, in step 806, the manner in which the generating device 1 determines the density of the element includes, but is not limited to:

For example, in the graph where the contour contour curvature is large or the contour curvature suddenly changes, in order to smoothly represent the corner or the change of the pattern, in step 806, the generating device 1 automatically increases the element density of the filling element; for the gentle graphic At step 806, the generating device 1 adopts a uniform packing density; some users may not like the preset packing density, and may set the packing density according to their own senses; the element density determined by one method alone does not satisfy the user's demand. When combined, two methods can be combined to determine one Element density.

Here, the method for generating a face text further determines that the element density of the hand-drawn graphic input by the user is filled with the fill element, and the element fill is performed on the hand-drawn graphic in combination with the element density, thereby further improving the generated face text and the hand-drawn graphic input by the user. The matching degree improves the user experience.

Preferably, the method for generating a face text further includes a step 807 (not shown), in which the generating device 1 stores the face text for direct selection and use by the user when inputting the next time. Specifically, the user saves the created face text by clicking, long pressing the save button, etc., in step 807, the generating device 1 stores the face text, for example, stored in the local face font of the user device. Or stored in the network character library connected to the user equipment through the network, and may be directly called when the user uses the same face text next time; or, in step 807, the generating device 1 uses the face text as the self. The definition picture is transferred to the element library; or, in step 807, the generating device 1 uploads the face text to the network character library for use by other users.

Here, step 807 enables the generating device 1 to store, dump, or upload the user-generated facial characters to facilitate the use of the user or other network users, thereby further improving the user experience.
