The authors wish to add one reference [1] to this paper [2].
On page 1, the original sentences are as follows: Progress toward new methods without cameras has been made through the use of accelerometer sensors mounted on the structure to capture floor vibration for human activities detection [13–15].
Correction to be: Progress toward new methods without cameras has been made through the use of accelerometer sensors mounted on the structure to capture floor vibration for human activities detection [13–16].
The sequential references originally in the paper (i.e., [16–47]) will shift by one (i.e., [17–48]).
The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
