The authors wish to make the following corrections to the article [1]. Parts of the Abstract, Introduction, Related Work, Methodology, Results and Conclusions sections were rephrased to reduce the overlap with our previous work [2]. In particular, we changed the following:
- In the Introduction, we better outlined our contributions with respect to our previous work, emphasizing that our main contribution concerns TTC estimation from aerial images.
- In the methodology Section 3.2, we shortened the last paragraph, removed Equation (1) and referred to our previous work [2], focusing on our novel contributions to TTC estimation from aerial images.
- Figure 3 was reproduced from [2] to facilitate the explanation of the novel methodologies. We added a sentence (figure reproduced from [2]) to the end of the caption.
- The results in Table 1 were reproduced from experiments published in our previous work [2] (see Table 10).
The authors state that the scientific conclusions are unaffected. The original publication has also been updated.
