In the Quadtree Partition, Images need to be encoded. IFS provides this issue a unique way. According to it, we construct the IFS model based on quadtree segmentation and find the model’s Hutchinson operator and IFS attractor. Based on the above, we re-establish WEMSDNM, during which traits of the field of business domain stand out. Comparing with the traditional algorithms by experiment, the result indicates that its performance has been improved to a certain extent.
