Abstract

The invention discloses an infrared small target detection tracking and identification method. Two different tree building methods of Max-tree and Min-tree are used for respectively detecting targetswith different brightness, the Max-tree mainly aims at a target of which the gray value is brighter than that of a background, and the Min-tree is mainly used for a target of which the gray value is darker than that of the background; two most significant features of the infrared small target, namely size information of the infrared small target and contrast information between the small target and the background, are extracted by using two attributes of an area attribute and a height attribute; and finally, tracking of the small target is realized through Mean-shift. The method has the following advantages: in the Max-tree and Min-tree, discontinuous pruning strategies are respectively used for two attributes, and results obtained by different pruning values under the same attribute and results obtained by different attributes are fused through different fusion strategies.
