摘要:According to the characteristics of cloud-drift area in an infrared sky-sea line image, we put forward a new shadow extraction method by using a layered reactive agent. The layered reactive agent includes a lower cloud search agent and higher management agent. The lower distributed layer search agent can sense local information of the image and retrieve the local cloud area in the image by locating operating point, enlarging scope, moving, marking, perishing, and so on. The higher management agent can sense the information of the whole and restrict and guide search action to the lower distributed search agent. The result of the simulation test shows the efficiency of this method is high, and this method extracts effectively and removes cloud in the infrared sky-sea image.
