    Cursor snapping is a standard method for providing precise pointing in direct manipulation graphical interfaces. In this paper, we introduce image snapping, a variant of cursor snapping that works in image-based programs such as paint systems. Image snapping moves the cursor location to nearby features in the image, such as edges. It is implemented by using gradient descent on blurred versions of feature maps made from the images. Interaction techniques using cursor snapping for image segmentation and curve tracing are presented
