Abstract:

In recent years, aerial infrared target tracking algorithms based on deep learning keep emerging. However, how to evaluate its performance has become an urgent problem to be solved. The complexity of the image is calculated by using the degree of the target being confused and the degree of the target being shielded of the single frame. The computing model of complexity of the sequence is designed based on the complexity of the image and the complexity of movement. Then, an infrared sequence sample database containing 420 sequences is constructed. A new algorithm evaluation method is proposed, in which the test results on the database are weighted through the complexity of the sequence. Experimental results show that it can comprehensively evaluate the performance of the algorithm in different states.

Key words: target tracking, complexity of image, complexity of movement, complexity of sequence, algorithm evaluation
