Problems solved by technology

[0002] In the field of image processing, due to various reasons, the border of an image may be too hard, resulting in aliasing
The traditional image anti-aliasing method requires a lot of interactive operations to achieve. Obviously, this method needs to consume a lot of manpower and time when batch processing image border aliasing, which is unacceptable.
Other existing anti-aliasing technologies are mainly designed for specific types of images or specific application fields, and are not universal

Embodiment Construction

[0055] The core idea of ​​the present invention is: first find the jagged boundary in the image through interactive means, then fit the boundary, and then perform repair operation on the pixels on both sides of the fitted boundary path to repair its gray value, and finally Calculate the fusion degree of each pixel (excessive pixel) on the path according to the boundary path to fuse the gray value of each pixel on the path, so as to achieve the ultimate purpose of anti-aliasing, and ensure that the width of the excessive pixel is one pixel width . Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] like figure 1 As shown, the image anti-aliasing system in this embodiment includes a boundary determination device 11 , a patching device 12 and a fusion device 13 .

[0057]The boundary determination device 11 is used to determine the boundary in the image that needs to be anti-aliased, and to fit ...

Abstract

The invention discloses an image sawtooth removing method. The removing method comprises following steps: firstly confirming a boundary of sawtooth which needs removing in an image, conducting fitting for the boundary, according to relation among pixel points in the range set by two sides of a route of the boundary and the closest boundary, and image transparency obtained by dismantling of the image, mending the pixel points of two sides of the route of the boundary, and finally calculating degree of fusion of the pixel points of the route of the boundary, and according to the degree of the fusion, conducting fusion for the pixel points of the route of the boundary. The invention further discloses an image sawtooth removing system. The image sawtooth removing method and the method achieve sawtooth removing of the image through small interactive modes and greatly improve efficiency of removing of the sawtooth of the image. By checking, processing effect of the image sawtooth removing method is not poorer than a manual mode of removing of the sawtooth.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image jagged elimination method and system. Background technique [0002] In the field of image processing, due to various reasons, the boundary of an image may be too hard, resulting in aliasing. The traditional image anti-aliasing method requires a lot of interactive operations. Obviously, this method needs to consume a lot of labor and time costs when batch processing image border aliasing, which is unacceptable. Other existing anti-aliasing technologies are mainly designed for specific types of images or specific application fields, and are not universal. For example, "Method and device for anti-aliasing of two-dimensional graphics" (Patent No. 200810224353) mainly solves the aliasing phenomenon in printed documents; sawtooth generated later. Contents of the invention [0003] In view of the defects existing in the prior art, the technical problem...
