The invention discloses a method for automatically withdrawing draft-based network graphics primitives. The method consists of the following steps: firstly, receiving keywords and drafts of target-describing graphics primitives input by subscribers and then acquiring a set of corresponding pictures according to keywords; utilizing visual attention calculation to analyze the visual attention area of each picture; taking the visual attention area as the initial value and acquiring a set of initial graphics primitives by an image withdrawing method; finally ordering the acquired initial graphicsprimitives according to the matching degree of keywords and drafts and selecting a plurality of graphics primitives with high matching degree as the target graphics primitives. The invention also discloses a system for automatically withdrawing draft-based network graphics primitives. The invention can automatically acquire the graphics primitives expected by subscribers according to keywords anddrafts input by subscribers and utilize a picture search engine to withdraw graphics primitives in huge volumes of network pictures. In addition, the invention with simple input and less artificial interference reduces the cost and improves the efficiency.
