Abstract

The embodiment of the present invention discloses an image processing method for improving the image boundary effect, which is applied in the field of image technology. The method includes: confirming the interpolation type of the interpolation point added to the image to be processed, and confirming the interpolation point according to the interpolation type Multiple adjacent pixel points, according to the comparison result between the absolute value of the pixel value difference between the multiple adjacent pixel points and the preset threshold, the pixel values ​​of the multiple adjacent pixel points, and the interpolation point and The distance between the plurality of adjacent pixel points is used to calculate the pixel value of the interpolation point, and the interpolation point is inserted into the image to be processed according to the pixel value of the interpolation point. The embodiment of the invention also discloses an image processing device for improving the image boundary effect, which can improve the clarity of the graphic boundary in the interpolated image.

Description

technical field [0001] The invention belongs to the field of image technology, and in particular relates to an image processing method and device for improving image boundary effects. Background technique [0002] In the information age, images, as the visual basis for human perception of the world, are an important means for human beings to obtain, express and transmit information. Digital image processing, that is, processing images with computers, is also developing day by day. When performing image enlargement processing, bilinear interpolation is usually used, that is, bilinear interpolation is performed horizontally and vertically to achieve the purpose of enlarging the image size. [0003] However, in the above-mentioned prior art, when the pixel values ​​of two original pixel points adjacent to the newly added interpolation point differ greatly (for example, pure black and pure white are adjacent), the pixel value of the newly added interpolation point is between th...
