Abstract
A picture obtaining method and apparatus and a picture processing method and apparatus are provided. The method includes: obtaining a grayscale image corresponding to a first picture and a first image, where a size of the first picture is equal to a size of the first image, the first image includes N parallel lines, a spacing between two adjacent lines does not exceed a spacing threshold, and N is an integer greater than 1; translating a pixel included in each line in the first image based on the grayscale image, to obtain a second image, where the second image includes a contour of an image in the first picture; and set a pixel value of each pixel included in each line in the second image, to obtain a second picture.
