Abstract: Knowledge automation techniques may include receiving a request for determining a representative image for a knowledge unit and determining a set of one or more images associated with the knowledge unit. The techniques may include providing the set of one or more images to a user on a client device and receiving user input indicative of a selection of a first image from the set of one or more images. Based on the first image, a thumbnail image for the knowledge unit can be generated. The techniques may further include associating the thumbnail image with the knowledge unit and displaying the thumbnail image to the user via the client device. In some embodiments, the techniques include generating a thumbnail image for a knowledge pack, wherein the knowledge pack comprises one or more knowledge units.

Abstract: A method for sketching and painting in a mobile terminal includes determining, when an image for sketching is selected, edges of the selected image, determining a type of a sketch mode and depicting a sketching process with the detected edges to correspond to the determined type of the sketch mode, and determining, upon a painting request for an image sketched through the sketching process, a painting mode and painting the sketched image to correspond to the determined painting mode.
