The dataset contains the navigation measurements obtained in the indoor experiment field. The volunteers move on the whole 4th floor of the Building D of Dong Jiu Teaching classes at Huazhong University of Science and Technology. Meanwhile, the experimental area consists of a total area of 717 m 2. These datasets were used and can be used to test and validate the radio map database updating-based localization positioning algorithm through the RSSI signals space.


The region-based segmentation approach has been a major research area for many medical image applications. A vision guided autonomous system has used region-based segmentation information to operate heavy machinery and locomotive machines intended for computer vision applications. The dataset contains raw images in .png format fro brain tumor in various portions of brain.The dataset can be used fro training and testing. Images are calssified into three main regions as frontal lobe(level -1, level-2), optus-lobe(level-1), medula_lobe(level-1,level-2,level-3).


Pen testing the method to evaluate the security of an application or network by safely exploiting any security vulnerabilities present in the system. These security flaws can be present in various areas such as system configuration settings, login methods, and even end-users risky behaviors.


Unit commitment and system data used in the following research paper:

G. Gutiérrez-Alcaraz, B. Díaz-López, J. M. Arroyo, and V. H. Hinojosa, “Large-scale preventive security-constrained unit commitment considering N-k line outages and transmission losses: System data.”


A practical alternative to the solution of the spectrum scarcity problem in wireless communication is the use of Cognitive Radio. The Primary users of which can be protected from secondary user interference by accurate prediction of TV White Spaces (TVWS) by using appropriate propagation modelling. In implementing any mobile communication system, the essential chore is to envisage the coverage of the projected system in a wide range. Also, the accurate determination of the propagation path loss leads to the development of efficient design and operation of quality networks.


Hardware tools used for drive test include:

1.Spectrum Analyzer (RF Explorer 3G combo model) 

2.Personal Computer (HP Laptop) 

3.Global Positioning System (GPS) receiver set

4.Mini-USB Cable 


6.Power Inverter 

7.vehicle for mobility purposes. 


The software tool used was the Touchstone-Pro software.



The dataset contains medical signs of the sign language including different modalities of color frames, depth frames, infrared frames, body index frames, mapped color body on depth scale, and 2D/3D skeleton information in color and depth scales and camera space. The language level of the signs is mostly Word and 55 signs are performed by 16 persons two times (55x16x2=1760 performance in total).



The signs are collected at Shahid Beheshti University, Tehran, and show local gestures. The SignCol software (code: , paper: ) is used for defining the signs and also connecting to Microsoft Kinect v2 for collecting the multimodal data, including frames and skeletons. Two demonstration videos of the signs are available at youtube: vomit: , asthma spray: . Demonstration videos of the SignCol are also available at and .

The dataset contains 13 zip files totally: One zipfile contains readme, sample codes and data (, the next zip file contains sample videos ( and other 11 zip files contain 5 signs in each (e.g. Signs(11-15).zip). For quick start, consider the

Each performed gesture is located in a directory named in Sign_X_Performer_Y_Z format which shows the Xth sign performed by the Yth person at the Znd iteration (X=[1,...,55], Y=[1,...,16], Z=[1,2]). The actual names of the signs are listed in the file: table_signs.csv.

Each directory includes 7 subdirectories:

1.      Times: time information of frames saved in CSV file.

2.      Color Frames: RGB frames saved in 8 bits *.jpg format with the size of 1920x1080.

3.      Infrared Frames: Infrared frames saved in 8 bits *.jpg format with the size of 512x424.

4.      Depth Frames: Depth frames saved in 8 bits *.jpg format with the size of 512x424.

5.      Body Index Frames: Body Index frames scaled in depth saved in 8 bits *.jpg format with the size of 512x424.

6.      Body Skels data: For each frame, there is a CSV file containing 25 rows according to 25 joints of body and columns for specifying the joint type, locations and space environments. Each joint location is saved in three spaces, 3D camera space, 2D depth space (image) and 2D color space (image). The 21 joints are visible in this dataset.

7.      Color Body Frames: frames of RGB Body scaled in depth frame saved in 8 bits *.jpg format with the size of 512x424.


Frames are saved as a set of numbered images and the MATLAB script PrReadFrames_AND_CreateVideo.m shows how to read frames and also how to create videos, if is required.

The 21 visible joints are Spine Base, Spine Mid, Neck, Head, Shoulder Left, Elbow Left, Wrist Left, Hand Left, Shoulder Right, Elbow Right, Wrist Right, Hand Right, Hip Left, Knee Left, Hip Right, Knee Right, Spine Shoulder, Hand TipLeft, Thumb Left, Hand Tip Right, Thumb Right. The MATLAB script PrReadSkels_AND_CreateVideo.m shows an example of reading joint’s informtaion, fliping them and drawing the skeleton on depth and color scale.
