Problems solved by technology

However, the inventor found in practice that due to the limitations of the drawing software itself, after importing pictures in common formats, such as pictures in formats such as JPG, GIF, TIF, BMP, and PDF, although it is convenient for users to view them in various environments, the The content of the picture cannot be edited, and the user must complete the sketch of the outline one stroke at a time based on the imported picture, which makes the sketching process too cumbersome for the user

Embodiment 2

[0081] Figure 4 It is a flowchart of a picture format conversion method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the first embodiment above. Specifically, refer to Figure 4 The image format conversion method provided in this embodiment specifically includes the following steps:

[0082] S201. Obtain the gradient modulus of each pixel in the bitmap image by using the HOG algorithm.

[0083] For obtaining the gradient modulus value of each pixel in the bitmap image using the HOG algorithm, reference may be made to the relevant description of S110 in the embodiment, and details are not repeated here.

[0084] S202. Obtain an absolute value for the gradient modulus value of each pixel.

[0085] Specifically, during the HOG feature extraction process of the bitmap image, since the pixel points of the bitmap image may be unevenly distributed, when the HOG algorithm is used for calculation, the gradient modulus may have posi...

Abstract

The invention discloses a picture format conversion method, a device, a device and a storage medium, which relate to the technical field of picture processing. The method comprises the following stepsof: acquiring the gradient modulus values of each pixel point in a bitmap picture; Searching contour points of each color region in the bitmap picture, wherein the contour points are determined according to the gradient modulus value of each pixel point; An editable graphic is generated, and the editable graphic is determined according to the outline points of each color region. The scheme solvesthe technical problem that pictures can not be edited after being imported into drawing software in the prior art, realizes the generation of editable vector format pictures based on the pictures innon-editable bitmap format, and facilitates the user to perform secondary operation on the pictures, thereby improving the user experience.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of picture processing, and in particular, to a picture format conversion method, device, device, and storage medium. Background technique [0002] When using drawing software, users often need to sketch pictures in the software, such as cartoon characters. In order to ensure the accuracy of the sketch, the user usually imports a picture for sketch reference into the software, and then sketches. However, the inventor found in practice that due to the limitations of the drawing software itself, after importing pictures in common formats, such as pictures in formats such as JPG, GIF, TIF, BMP, and PDF, although it is convenient for users to view them in various environments, the The content of the picture cannot be edited, and the user must complete the sketch of the outline stroke by stroke based on the imported picture, which makes the sketch process too cumbersome for the user. Conte...
