Research on Burst Image Segmentation Based on Brightness Decrease Diffusion

Abstract

The image of a projectile explosion shows the characteristics of multi-regional and uneven brightness distribution. The image brightness decreases from the centre to the edge area and the image appears to be blurred at edge. This phenomenon would affect the burst segmentation and the gravity centre location. By analyzing the brightness distribution and decrease of the burst image, it could be deduced that the uneven brightness distribution can affect the shape and the location of burst gravity centre. This paper focuses on the affect of region growing criteria of the brightness decrease diffusion on the segmentation and positioning of the burst. Furthermore, it proposes the criteria of dynamic growth, which iterate based on the gravity centre position distance of the adjacent region growing segmentation to realize burst image location. The test results show that the method is effective and with higher stability and reliability.
