In order to realize the infrared point targets detection and tracking under complicated sea-sky background,an algorithm that can detect and track targets synchronously is proposed based on a double matching mathematical mode.The model adopts a mark image sequences M to memorize the input image sequences match result,a mark image T to memorize the mark image sequences match result,a statistical image S to memorize the successful match times of each pixel in the image T,and matrixes T and Sto show moving targ...
