Abstract

The invention discloses a multifunctional image style migration method based on wavelet analysis. According to the technical scheme, the method comprises the steps of image wavelet decomposition, image wavelet coefficient processing and image wavelet coefficient reconstruction to generate a final effect image. The method has the beneficial effects that the style of the reference image can be efficiently migrated to the input image, and the texture information of the reference image can be fused into the input image, so that the effect of style migration and texture fusion is realized.

Description

technical field

[0001] The invention belongs to the technical field of computer image processing, and relates to a multifunctional image style transfer method based on wavelet analysis. Background technique

[0002] The existing image style transfer technology refers to the technology of using various algorithms to transfer the style (such as color) of the reference image to the input image. Image style transfer technology is to regenerate a new image according to the style of the reference image and the content of the input image. However, the image style editing system of the present invention can realize three functions at the same time, that is, the style of the reference image can be transferred to the input image; the texture information of the reference image can also be integrated into the input image, thereby realizing the effect of style transfer and texture fusion ; At the same time, it can also realize the sketch style editing effect of the input image.

Embodiment Construction

[0035] Below in conjunction with specific embodiment, the present invention is described in detail (principle diagram is as figure 1 shown).

[0036] 1. Wavelet decomposition of images;

[0037]

[0038] n and m are row subscripts and column subscripts, respectively.

[0039] {h k} k∈Z Is the low-pass filter coefficient, that is, let the low-frequency signal pass. h, g are standard filters, is the conjugate of h, c is the low-frequency coefficient, and k is the wavelet decomposition scale.

[0040] 2. Image wavelet coefficient processing

[0041]

[0042] called sequence for c k+1 The first-order two-dimensional wavelet transform of .

[0043] For an image of 1000*1000 pixels, the wavelet transform scale is 8. When the pixel size is larger or smaller, the wavelet transform scale is scaled up or down accordingly.

[0044] 3. Image wavelet coefficient reconstruction to generate the final effect image

[0045] Suppose the coefficient after wavelet decompositi...
