### WATSS: a Web Annotation Tool for Surveillance Scenarios ###
A web based annotation tool to create ground truth for datasets related to visual surveillance and behavior understanding.
Our tool can easily manage datasets with multiple cameras. It allows annotating a person location in the image, its identity, its body and
head gaze, as well as a potential occlusion or group membership.
- /css: style sheets
- /DB: scripts to generate and popolate the database
- /fonts: font files
- /frames: contains the frames to label with WATSS
- /gt-making: main page of WATSS
- /img/real_people: contains one representative image for each annotated people
- /php: contains api.php with functions to run queries and connection.ini where are stored the parameters for the connection with the database (it is automatically generated through /DB/config.py script)
- contributors.txt: peoples who have contributed to implement WATSS
- export.php: script to export the entire databse in CSV
- index.php: home page
- legend.html: contains the keyboard shortcuts
- Readme: The file you are reading now :)...
This file allows to set some parameters of WATSS. Before running the tool the user must modify this file. Each section of *config.conf* file is showed in the follow:
- [DBConnection]: contains the user/password/host/db parameters to connect WATSS with the database.
**Note: the database must be created manually from a mysql client, and the user specified in the db parameters must be granted privileges on this database. We also assume MySQL is listening on default port 3306**
- [camera]: cameras information: ids and potential calibration information.
- [user]: initial annotator usernames
- [poi]: definition of poi (point of interest):
- each poi is defined using [poi_POI NAME] and the cameras in which it appears. For each camera a location_x,location_y,width and height is defined.
QUICK START INSTRUCTIONS:
1. Put WATSS code on web server e.g. by cloning the repo.
**Note: ensure WATSS has write privileges for the folder /img/real_people**
2. Go to the */frames* folder (or create this folder if not exist)
3. Create a folder for each camera to use with WATSS, e.g. 1,2,...N in the *frames* folder.
**Note: you can use only numeric notation for folder names**
4. For each camera_id insert in the folder */frames/camera_id* all the relative images
**Note: the image will be ordered considering the name and the extension of the images**
5. Set the parameters in the configuration file *config.conf* (see Above)
6. Go to the folder DB and run: python DB/config.py
**Note: this python script generates the sql script insertData2DB.sql to insert the data in the database**
7. Import the *DB/createSchemaDB.sql* script in a MySQL client to create the schema of the database
8. Import the *DB/insertData2DB.sql* script in a MySQL client to insert the data in the database
You should be able to start annotating opening a Web browser at: http://localhost/watss/
