Embodiment 1

[0053] see figure 1 , the present embodiment provides a bitmap-based hand-painted material generation method, including the following steps:

[0054] S1, enhancing the bitmap image, to highlight the trend of pixel value variation of the bitmap image;

[0055] S2. According to the variation trend of the pixel value, the image outline is generated by connecting lines;

[0056] S3. Denoising the image contour to generate a denoised image contour;

[0057] S4. Embedding the bitmap image into the outline of the denoised image to generate a hand-painted material.

Embodiment 2

[0059] see figure 2 Correspondingly, this embodiment provides a device for generating hand-painted materials based on bitmaps, including:

[0060]The enhancement module 1 is used to enhance the bitmap image, so as to highlight the variation trend of the pixel value of the bitmap image;

[0061] The connection module 2 is used to generate an image outline by connecting a line according to the variation trend of the pixel value;

[0062] Denoising module 3, for denoising the image contour, to generate denoising image contour;

[0063] The embedding module 4 is used to embed the bitmap image into the outline of the denoised image to generate hand-painted material.

[0064] It should be noted that the bitmap-based hand-painted material generation method or device highlights the change trend of the pixel values ​​of the bitmap image by enhancing the bitmap image, and then generates an image outline by connecting the change trend of pixel values, and denoising generates a denoisi...

Embodiment 3

[0067] see image 3 , the present embodiment provides a method for denoising an image contour to generate a denoised image contour, comprising the following steps:

[0068] S30. Deduplicating the image contour to generate a deduplicated image contour;

[0069] S31. Group deduplicated image contours to generate grouped image contours;

[0070] S32. Sorting grouped image contours to generate denoised image contours.

Abstract

The invention belongs to the technical field of hand drawing animation, and provides a bitmap-based hand drawing material generation method, which comprises the steps of enhancing a bitmap image, highlighting a pixel value change trend of the bitmap image, generating an image contour through a connection pixel value change trend, denoising to generate a denoised image contour, and then embedding the bitmap image into the de-noised image contour to generate a hand drawing material, so that the bitmap has a contour path and becomes a displayable hand drawing material. The bitmap image can be vividly and efficiently restored by drawing along the contour path of the bitmap when a user performs hand drawing, thereby greatly reducing the drawing loss, accelerating the rapid generation of the image. and improving the user experience. In addition, the threshold and the cost for the user to prepare the hand drawing animation material are reduced, and the hand drawing animation effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of hand-painted animation, and in particular relates to a bitmap-based hand-painted material generation method, device, electronic equipment and storage medium. Background technique [0002] In hand-drawn animation, hand-drawn materials need to be obtained first. At present, the production of hand-painted materials usually needs to be drawn with professional tools, and the professional requirements and production costs for production personnel are relatively high. [0003] Bitmap is currently a more common image format on the Internet. It can be obtained from various picture websites. The output files taken by devices such as cameras and mobile phones are also bitmaps, but the bitmap itself is composed of pixels and has no path information. Unable to complete the hand-drawn animation display. [0004] Therefore, how to use bitmaps to generate hand-painted materials is an urgent problem to be solved. Cont...
