Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail: as figure 1 Shown, be the method flow chart of the method flow chart that generates shaded subtitle based on the structure of word among the present invention, comprise the following steps:
[0016] Step 101, decompose the subtitle text and subtitle shadow into text blocks and shadow blocks according to the character structure.
[0017] Subtitle text can be decomposed into several text blocks according to its own structural characteristics; correspondingly, subtitle shadow can also be decomposed into several shadow blocks. For example, subtitles with a top-bottom structure can be decomposed into upper and lower parts; subtitles with a left-right structure can be decomposed into left and right parts. The subtitle shadow comes from the processing of the subtitle text, so similar decomposition can also be performed.

The embodiment of the invention discloses a method for generating shadow captions based on structures of characters, which comprises the following steps: according to the structures of the characters, decomposing caption characters into character blocks, and decomposing caption shadow into shadow blocks; placing the character blocks and the shadow blocks on different white board respectively in aunique corresponding mode of texture coordinates; and superposing the white board for placing the character blocks and the white board for placing the shadow blocks to generate the shadow captions. The method for generating shadow caption based on the structures of the characters is characterized in that after the white board for placing the character blocks and the white board for placing the shadow blocks are superposed, the method also comprises the step of realizing the stunt of the shadow caption by the movement of the white board for placing the character blocks and the white board for placing the shadow block. The method for generating shadow caption based on the structures of the characters achieves the effect of rapidly generating the shadow captions which have various modes.
Description
technical field [0001] The invention relates to the field of multimedia technology, in particular to a method for generating shaded subtitles based on character structures. Background technique [0002] In the currently commonly used video subtitle generation software, users can add shadows to the text in the subtitles. After adding the shadows, the subtitle texts produce a floating effect, which enhances the three-dimensional and layered sense of the picture. At the same time, the addition of shadows also makes the lines of the subtitle text more prominent, which is conducive to presenting the subtitles more strikingly in front of the audience. [0003] In Premiere's subtitle editor, special tool options are provided for shadow design. Users can generate various color shadows for subtitles according to their needs, and can also set the shadow position through the work area in the lower left corner of the editor. Shadows in Premiere come in three styles: Single, Solid, and ...
