Task-guided segmentation and its application in real-time IR ship recognition

In this paper, existing segmentation approaches are summarized. The Otsu method is found to fit for real-time implementation but sensitive to target size. If target is too small compared with the background, it always cannot be segmented. To solve such problem, a task-guided segmentation is proposed. In such model, with the idea of attention, image segmentation is processed under the guidance of tasks at hand. A model of task-guided segmentation is proposed and is applied in real-time IR ship recognition. Experimental results demonstrated the effectiveness of the approach proposed.
