Infrared Small Target Detection Based on Density Peak Search and Local Features

Figure 6

Test results of the proposed algorithm: (a) shows the original image of the dataset; (b) shows the 3D image of the source image; (c) shows the image density peak search result; (d) shows the fused 3D image of the eight-directional gradient responses of the candidate target points; (e) shows the 3D image of the test result after threshold segmentation; and (f) shows the position of the final detected infrared small target.
