Problems solved by technology

[0004] The model-based non-photorealistic rendering generation method needs to model the scene and interact with people to generate it, and requires certain painting techniques to create a satisfactory painting, so it cannot meet the needs of various scenes and automatic processing , which is not universal in automatically generating watercolors
[0005] The image processing and rendering generation method based on real images meets the needs of various scenes. At present, it is generally generated by complex design of real images through image editing software such as Photoshop. This method needs to be completed on the PC side, and requires certain computer and art skills. Basic, time-consuming design, unable to meet the needs of automatic generation

Embodiment Construction

[0043] In one embodiment, such as figure 1 As shown, a method of generating a watercolor style image, including:

[0044] Step S102, acquiring an original image.

[0045] The original image is the image to which you want to add a watercolor-style artistic effect. In one embodiment, the photographing event of the smart terminal can be monitored, and when the photographing event of the smart terminal is captured, the photographed photo is automatically obtained as the original image.

[0046] Step S104, blurring the original image to generate a blurred image.

[0047] Blur the original image, that is, filter the original image through an image blur filter.

[0048] In one embodiment, a Gaussian blur can be performed on the original image to generate a blurred image.

[0049] In this embodiment, the original image may be filtered by using a separable Gaussian filter to perform threshold judgment and convolution on the original image.

[0050] The separable Gaussian filter is...

Abstract

The invention relates to a method for generating a watercolor style image. The method comprises that an original image is acquired; the original image is subjected to blurring processing, a blurred image is generated; edge detection is carried out on the blurred image, an edge image is generated; the edge image is subjected to inverse color processing, an inverse color image is generated; the blurred image and the inverse color image are subjected to Alpha mixing, and the watercolor style image is generated. In addition, the invention further provides a device for generating the watercolor style image. According to the method and the device for generating the watercolor style image, processing speed can be improved, and the generated watercolor style image shows abundant and flexible color effect and transparent and vacant visual feeling.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for generating watercolor style images. Background technique [0002] In daily life, in order to make the photos have a certain artistic style after taking pictures, people usually post-process the photos to stylize the photos to generate pictures with artistic effects, such as generating pictures with the style of watercolor paintings. [0003] At present, there are two methods for generating watercolor style images, one is the image processing and rendering generation method (IBR) based on real images, and the other is the non-photorealistic rendering generation method (NPR) based on the model. [0004] The model-based non-photorealistic rendering generation method needs to model the scene and interact with people to generate it, and requires certain painting techniques to create a satisfactory painting, so it cannot meet the needs of various scenes a...
