采用行均值相减法抑制温度场的非线性影响，增强目标点，利用形态学方法抑制背景并保留高亮区，搜索局部极大值，利用阈值分离出目标，实现红外点目标的检测
English Description：
The nonlinear influence of the temperature field is suppressed by using the line mean subtraction method, and the target points are enhanced. The background is suppressed and the highlight area is retained by using the morphological method, and the local maximum is searched. The target is separated by using the threshold value, and the infrared point target is detected
