A1
Abstract:
An image annotation method and apparatus, and a computer system and a readable storage medium. The method comprises the following steps: receiving an image, and carrying out grayscale treatment on the image to generate a processing image; receiving a paintbrush trajectory, obtaining a starting point coordinate, an end point coordinate and sampling points of lines from the paintbrush trajectory, and storing the sampling points in a line stack; drawing a straight line from the starting point coordinate to the end point coordinate to generate a closed line according to the starting point coordinate, the end point coordinate, the sampling points of lines and the closing rule, extracting the straight line sampling points of the straight line, storing same in the line stack, and outputting the sampling points in the line stack to a client; or setting the line as a non-closed line according to the starting point coordinate, the end point coordinate, the sampling points of lines and the closing rule, and outputting the sampling points in the line stack to the client (2); and receiving line selection information and line movement information, and adjusting the position of the line.
