The invention discloses an MPS simulation method based on a partitioning strategy, and relates to the technical field of image processing. The MPS simulation method solves the technical problem of simulation of non-steady images. The method comprises the steps of firstly partitioning a non-steady training image into multiple steady training partitioned blocks, then selecting one training partitioned block from the training partitioned blocks to serve as a reference partitioned block, and referring to a target object in the reference partitioned block to conduct geometric transformation on theother training partitioned blocks respectively in a rotating and scaling mode; then traversing images of all the training partitioned blocks, and constituting a probability information base with probability information of the images of all the training partitioned blocks; then using the MPS simulation method and the probability information base to simulate or reconstruct a non-steady target image.The MPS simulation method based on the partitioning strategy can be widely applied to the fields like weather forecasting, environment prediction, agriculture and forestry, and exploration of marineresources.
