2. The details of the main technical components of this work are not provided. As for false positive class, I don’t see how it is used in the re-id system.   \end{quote}  \textit{We thank the reviewer for pointing this out. If this matter is not clear, we shall endeavor to \textbf{make} it clear.}  \textit{In figure 2, we assume the Single-frame Classifier is a classifier that will classify input images as one of the persons available in the training set. Therefor, Therefore,  when a classifier that only has classes for people, receives an input image of a fire-extinguisher (figure 5) it always fails to correctly classify (there is no correct class!).} \textit{In Section 5.2.2 Single frame Re-Identification we cite [19] as the algorithm employed to enact classification. [19] describes a multi-class classifier, that does not, by default, contains an extra class for unclassifiable inputs. Therefore, when using the "FP Class module", we are in fact providing the re-identification classifier algorithm with extra training samples for it to train an extra class, a class of detection false positives.}  \textit{For this to be clearer we have edited the 5.4 Scenarios section thusly:} 

\begin{quote}  6. I don’t see the difference between the original precision/recall and the proposed precision/recall. I think the paper needs more specific description on them.  \end{quote}  \textit{Well pointed out. We did not mean to imply we had innovated in this aspect, therefor therefore  we edited the corresponding part of the abstract to} \textbf{\textit{In this paper, we apply precision and recall metrics to evaluate such integrated system}} 

3. I think the Window-based Classifier is exactly multi-shot. Some other multi-shot methods also do not require contiguous frames and in-camera trackers. The proposed Window-based Classifier is straightforward and reasonable. As an important contribution, it's better to compare it with other other multi-shot methods, such as reference [4].  \end{quote}  \textit{We thank the reviewer to point this out, as it makes clear that we must clarify in the text that multi-shot algorithms that we are aware of (such as [4]) require a way to specify which images belong to a single person (such as a tracker or manual selection) prior to being able to analyze those images in a multi-shot fashion. No multi-shot algorithm that we are aware of does some kind of unsupervised clustering first to try and discover which images belong to a same individual, to then be able to use such data in a multi-shot fashion without a tracker or human intervention.   Therefor, Therefore,  we have enhanced the clarifying paragraph thusly:} \textbf{\textit{Although this procedure is similar to multi-shot, it requires less information. In this work, window-based classification works with any single-shot re-identification algorithm, and does not require an in-camera tracker or manual selection of the images that belong to each individual, contrary to all of the works that do multi-shot re-identification known to the authors.}}
