Embodiment Construction

[0026] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0027] This embodiment provides a multi-channel based WordArt generation method, taking the source text image and the target text image as a single channel, and the source WordArt image and the target WordArt image as R, G, and B three channels as an example, figure 1 as its flow chart, with figure 2 As an example, to demonstrate the process of using this method to generate the target wordArt "Shu" from the target word "Shu" based on the source word and its wordArt "Huo", the specific steps are as follows:

[0028] Step 1: For the input source text image T S , using the morphological skeleton extraction operation to extract its literal skeleton S S , calculate every pixel in Ts to skeleton S S distance, so as to obtain the offset image O of the source tex...

Abstract

The invention provides a multi-channel-based wordart generation method and system. The method includes the following steps that: the offset images of a source word image and a target word image are extracted; the source word image, the offset image of the source word image and a source wordart image are combined into a multi-channel source image cube according to channels; a target wordart image is initialized, and the initialized target wordart image, the target word image, and the offset image of the target word image are combined into a multi-channel target image cube according to channels;similar image blocks of each image block in the target image cube are iteratively searched in the source image cube, and the wordart image channels of the similar image blocks are adopted to update the corresponding channels of the target image cube until convergence occurs or the update degree of the target image cube is smaller than a set threshold; and the wordart image channels of the targetimage cube are extracted, and the target wordart image can be generated.

Description

technical field [0001] The invention relates to the technical field of image texture synthesis, in particular to a multi-channel-based artistic word generation method and system. Background technique [0002] With the development of multimedia technology and the improvement of people's aesthetic taste, more and more people begin to pay attention to the aesthetics of visual information. Among them, text is one of the most important parts of daily life, and it has become an important research hotspot to beautify it, generate artistic words, and improve its subjective visual quality. [0003] The key to wordart generation is to synthesize the texture of the text and add colorful texture information to the target text. One approach for texture synthesis is the sample-based texture replication technique. These techniques synthesize new textures in the target image by copying texels or texture blocks from the source texture map. However, these methods ignore the diversity and c...
