Forward-looking infrared image segmentation based on region growing

XIA Jing,SUN Ji-yin(The Second Artillery Engineering Institute,Xi′an 710025,China)  
Infrared imaging guidance technology has been the main trend in the development of precision guidance technology today by reason of its predominant capability.Accurate infrared image segmentation is the basis for realizing target recognition.Aiming at the features of forward-looking infrared image and the purpose of image segmentation in imaging guidance technology,a novel segmentation algorithm based on region growing is proposed.Firstly the seed region is selected based on global threshold segmentation and partial gray scale statistics criterion and strategy is defined to choose the seeds in the region.Then regarding the area of target template as the reference,the growing threshold is adjusted automatically for region growing through the estimation of segmentation effect.Finally,the segmented image is obtained.Experimental results show that the target information gained by the proposed algorithm is complete and exact and the result greatly facilitates the target matching recognition based on edge feature.
