Aircraft Group Recognition Based On Archimedes Spiral

摘要

Although the recognition of dense population has already been very mature, the methods and strategies of sparse target groups recognition are still few. In this paper, a sparse group target recognition method based on Archimedes spiral is proposed, which has rotation invariance and scale invariance, so the recognition accuracy is greatly improved. At the same time, a similarity measure method based on probability density function and loss function is presented. In terms of identifying aircraft groups, accuracy is greatly improved compared to other methods.
