Problems solved by technology

[0002] In the process of image processing, when the image is rotated or matrix transformation is used to operate the image, since the image is transformed to form a certain angle with the background, the edges of the previewed image will have obvious jagged edges; although the existing Technology uses the performance of the graphics card or multi-layer images to solve the aliasing problem, but the efficiency is relatively low

Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Such as figure 1 Shown, a kind of method for eliminating image edge jaggedness of the present invention, it comprises the following steps:

[0025] 10. Obtain the original image to be rotated or matrix operated;

[0026] 20. The outermost edge of the original image is processed to reduce transparency to obtain a processed image;

[0027] 30. Perform a rotation operation or a matrix operation on the processed image to obtain a result image.

[0028] In this embodiment, the transparency reduction process in step 20 is mainly to uniformly set the...

Abstract

The invention discloses a method for eliminating edge sawteeth of images. The method has the advantages that the transparency of the outermost peripheral edges of the original images is reduced to obtain processed images, then rotation operation or matrix operation is carried out on the processed images, accordingly, obtained result images can be in natural transition to backgrounds, previewed sawteeth are not obvious or can be prevented, and good visual effects can be realized; algorithms of the method are simple, the method is high in processing speed, and operation is simple and convenient.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for eliminating jagged edges of an image. Background technique [0002] In the process of image processing, when the image is rotated or matrix transformation is used to operate the image, since the image is transformed to form a certain angle with the background, the edges of the previewed image will have obvious jagged edges; although the existing Technology uses the performance of the graphics card or multi-layer images to solve the aliasing problem, but the efficiency is relatively low. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for eliminating jagged edges of an image, which is easy to operate and has good effect. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A method for eliminating jagged edges of an image, comprising the following ste...
