Abstract

The profilogram of FAE (fuel-air explosive) fuel explosion image is the important base to analyze the explosion process. In this article, the double peak method, the iteration method, the OTSU method, and the maximum entropy criterion method are respectively used to confirm the threshold, and extract and compare the profilograms of the FAE fuel explosion image, which could establish the base for the further experiment analysis.

Highlights

FAE first occurred in 1960s-1970s, and it is one the most important conventional weapons, with the name of “mini-nukes”
If the extraction of profilogram is not exact, the subsequent analysis would face large error, even false result, so the profilogram extraction method according with the explosion image should be found and researched
The profilogram is to connect the marginal points in the image according to certain strategy, and it is the very important base of many aspects such as the image segmentation, the target region identification, and the regional formation extraction in the image analysis domain

Summary

Introduction

FAE first occurred in 1960s-1970s, and it is one the most important conventional weapons, with the name of “mini-nukes”. Since it came out, the fuel, the warhead structure, and the ignition mode all have been developed largely (Kenneth S Brower, 1987, P.1405 & Bull C, 1982, P.7-22). To quicken the research and application of FAE weapons is very important to enhance the national defense strength of China, and strengthen the fighting capacity of the force. The throwing rule and the clouds formation of the FAE fuel explosion are the most important research content in the FAE studies, and many research institutions in China and foreign countries have developed the research about this aspect in succession. If the extraction of profilogram is not exact, the subsequent analysis would face large error, even false result, so the profilogram extraction method according with the explosion image should be found and researched
