Problems solved by technology

This method uses the offset channel to constrain the spatial position distribution of the texture around the text, but this requires the style picture to be a word art picture and the corresponding original text picture as a guide
Strict restrictions on the input limit the application scenarios of the method
At the same time, this kind of method is only for the artistic word itself, without considering the combination of the text and the background image, and cannot be used to automatically generate posters

Embodiment Construction

[0040] The detailed method flow of the present invention is further described below:

[0041] figure 1 It is a demonstration diagram of the poster generation method combining graphics and text of the present invention, figure 2 The flow chart of the method. As shown in the two figures, the method of the present invention includes the following steps:

[0042] Step 1: Calculate the placement position of the target text in the background image to obtain the text placement area, which specifically includes:

[0043] a) For the input background image I, style image S, and target text image T, calculate the variance of the pixel value in the x neighborhood of each pixel in the background image I as a variance penalty:

[0044] U v (x)=var(Ψ(x)) (1)

[0045] Among them, Ψ(x) is the image block centered at x, and var(·) is the variance operation.

[0046] b) Use the saliency detection method to calculate the saliency at each pixel x in the background image I as a saliency penalty:

[0047] U ...

Abstract

The invention discloses a poster generation method and system which combine picture and text. The method comprises the following steps: given a target text, a style picture and a background picture, firstly, automatically determining the position of the target text in the background picture; then the background of the style image is segmented. Then the contour of the target text is adjusted according to the contour of the foreground of the style picture. Finally, under the guidance of the adjusted structure of the target text and the pixel constraint of the background picture, the image blockof the style picture is filled into the target text in the placement area of the background picture, so that the art character with the style of the style picture is embedded into the background picture, the picture and the text are combined, and an artistic poster is automatically generated. The invention automatically determines the optimal position of the text in the background picture by considering a plurality of factors. Considering the contour adjustment and the pixel constraint of the text structure and background image, the generated posters have better subjective visual quality.

Description

Technical field [0001] The invention belongs to the technical field of image texture synthesis, and specifically relates to a poster generation method and system combining graphics and text. Background technique [0002] Graphic design is widely used in daily life, posters, magazine covers, print advertising design and other such media that combine pictures and text, can better convey information, but the manual production process of combining pictures and texts is tedious and requires certain skills. The automatic poster generation method has great commercial value. [0003] The key technology of poster generation is texture synthesis, which adds texture information representing style to the target text. Although texture synthesis is widely used, there are fewer ways to use texture synthesis to generate WordArt. A method of artistic character generation is based on a multi-channel artistic character generation method. This method uses an offset channel to constrain the spatial ...
