I apologize for my previous rudeness, but I do have some issues that I would like to discuss rationally with you. as follows. First, I think the code in the paper that is open sourced for others to study should at least be available or error-free, not just use github as our own code repository.

There are a lot of code writing errors in this project. 1.Where is the definition or introduction of the function get_mask_from_bbox() in line 83 of the tracker.py file in the deep_sort folder? 2.What’s the meaning of the parameter “tn=self.tn” of the function update() in line 95? 3.Where is the definition or call of the function compute_mean_depth_from_mask() in line 434? 4.Where is the definition of the variable only_extrapolate in line 161 of the tracker_mask.py file? 5.Does the function project() require a parameter called temporal_noise in line 301 of the kalman_filter.py file? 6.and so on Please double check and update the code carefully when you have time. Also, I have a question, are the results stated in the paper based on this project??

Second, the project is not coding standard. 1.There are a lot of unused imports in the project, such as “import ast” in detection.py, cv2 in kalman_filter.py, and so on. 2.In addition, in the kalman_filter.py file, the type of tn was originally int, later in the line 92 tn became a dict? Shouldn't the correct way to write line 80 be “if not tn”?

Finally,I previous said that the necessary comments are missing in the code, like 1.what exactly is the meaning of tn mentioned above? Whether it is a glyph or a dict with specific meaning is not given in the code. 2.In line 132 of Kalman_filter.py, the function project() requires 5 parameters. Why are there no corresponding annotations for the other 3 parameters except the mean and covariance parameters that were originally in the deep_sort project? There are many such cases, please check carefully when you have time, and add this part of the note if you can.

Detecting Invisible People is a funny stuff, I wanted to peruse the code for this project, but it was kind of bad, and reading it made me so irritable, hence i raise yesterday's issue. I think not only we must learn to be a rational person, also we should be rational and rigorous with our own research and works. The above are some of the questions I have raised. I am looking forward to your reply.

I think this is something that only the author can understand, or not.Why is there no manual?and there are no comments in the your code, Reading this makes me cranky!!!!!!

Thanks for your great work, is there any code available to visualize the tracks in 3D as shown in the website? https://www.cs.cmu.edu/~tkhurana/imgs/teaser.gif
