The embodiment of the invention discloses an image processing method for improving an image boundary effect and belongs to the technical field of images. The method comprises the following steps: 1, determining an interpolation type of an interpolation point newly added to the to-be-processed image; determining a plurality of adjacent pixel points of the interpolation point according to the interpolation type; and calculating the pixel value of the interpolation point according to the comparison result of the absolute value of the difference between the pixel values of the plurality of adjacent pixel points and a preset threshold, the pixel values of the plurality of adjacent pixel points and the distance between the interpolation point and the plurality of adjacent pixel points, and inserting the interpolation point into the to-be-processed image according to the pixel value of the interpolation point. The embodiment of the invention further discloses an image processing device for improving the image boundary effect, and the definition of the image boundary in the interpolated image can be improved.
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...
