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

Figure 3

Density peak search: (a) column shows the missed detection of unprocessed DPS on some IR images; (b) column shows the ρ–δ feature space of unprocessed images with density peaks indicated by blue dots and target points marked by red circles; (c) column shows the candidate target detection after preprocessing; and (d) column shows the ρ–δ feature space of the preprocessed image, with density peaks indicated by blue dots and target points marked by red circles.
