Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] The inventor found in the research that the reasons for the "glitch" (sawtooth shape) include: since the composition unit of the computer screen can be regarded as a matrix composed of some pixels, different pixels are "painted" with different colors, so it can be Represents a series of different images. Among them, the pixels can only be painted or not painted, and the painting can only paint the whole of it, not a fraction of it. Therefore, when the edge line of the area t...

Abstract

The invention provides an image burr removing method and a related device, wherein the method comprises the steps: respectively setting a preset number of auxiliary points for each pixel point involved in a to-be-colored region of a to-be-loaded image of QT software, wherein the number is not less than 2; determining the number of auxiliary points contained in each target pixel point, wherein thetarget pixel points comprise pixel points located in the to-be-colored area and a pixel area located in the to-be-colored area in the pixel points penetrated by the edge line of the to-be-colored area; determining the transparency of each target pixel point according to the ratio of the number of the auxiliary points contained in the target pixel points to the preset number, wherein the smaller the ratio corresponding to the target pixel point is, the larger the transparency value is. The less the auxiliary points included in the target pixel points at the edge of the to-be-colored area are, the greater the transparency value is, and the lighter the color of the target pixel points is, so that the burrs can be visually eliminated.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method and a related device for removing burrs from an image. Background technique [0002] When drawing in the Qt Company (Qt) software, the visualization operation of loading images, for example, the visualization operation of loading maps, some jagged shapes will appear on the lane lines of some roads in the loaded map, that is, "burrs", which are sensory and data There is a certain impact on testing. In order to visualize the "glitch" in the image, figure 1 An example of a "glitch" is given, from figure 1 It can be seen that there are many "burrs" on the edge of the lane line of the road, which affects the visual effect. [0003] Therefore, removing the "burr" is a problem to be solved. Contents of the invention [0004] The present application provides an image burr removal method and a related device, aiming at removing burrs in an image loaded by QT. ...
