The dataset was captured by a Kinect device. There are 12
dynamic American Sign Language (ASL) gestures, and 10 people. Each person
performs each gesture 2-3 times. There are 336 files in total, each corresponding
to a depth sequence. The hand portion (above the wrist) has been segmented. The
file name has the format sub_depth_m_n where m is the person index. n ranges from 1 to 36. Note that for some (m,n), the file sub_depth_m_n does not exist. For example,
there is no "sub_depth_02_03". The reason is that some of the bad
sequences are excluded from the dataset. The mapping from n to gesture type is
Each file is a MAT file which can be loaded with 64bit MATLAB. Below is a sample MATLAB code to load a file:
width = size(x.depth_part,1);
height = size(x.depth_part,2);
nFrames = size(x.depth_part,3);
depthval = x.depth_part(i,j,k);
The following two papers reported experiment results on this dataset:
 Alexey Kurakin, Zhengyou Zhang, Zicheng Liu, A Real-Time System for Dynamic Hand Gesture Recognition with a Depth Sensor, EUSIPCO, 2012.
 Jiang Wang, Zicheng Liu, Jan Chorowski, Zhuoyuan Chen, Ying Wu, Robust 3D Action Recognition with Random Occupancy Patterns, ECCV, 2012.
The dataset was captured by using a Kinect device. There
are 16 activities: drink, eat, read book, call cellphone, write on a paper, use
laptop, use vacuum cleaner, cheer up, sit still, toss paper, play game, lie
down on sofa, walk, play guitar, stand up, sit down. There are 10 subjects.
Each subject performs each activity twice, once in standing position, and once
in sitting position. There is a sofa in the scene. Three channels are recorded:
depth maps (.bin), skeleton joint positions (.txt), and RGB video (.avi). There
are 16*10*2=320 files for each channel. In total, there are 320*3=960 files.
Note that the RGB channel anddepth channel are recorded independently, so they
are not strictly synchronized.
The format of the skeleton file is as follows. The first integer is the number of frames. The second integer is the number of joints which is always 20. For each frame, the first integer is the number of rows. This integer is 40 when there is exactly one skeleton being detected in this frame. It is zero when no skeleton is detected. It is 80 when two skeletons are detected (in that case which is rare, we simply use the first skeleton in our experiments). For most of the frames, the number of rows is 40. Each joint corresponds to two rows. The first row is its real world coordinates (x,y,z) and the second row is its screen coordinates plus depth (u, v, depth) where u and v are normalized to be within [0,1]. For each row, the integer at the end is supposed to be the confidence value, but it is not useful.
Activity recognition experiment with this dataset is reported in the following paper:

action 2 or 3 times. There are 567 depth map sequences in total. The resolution
is 640x240. The data was recorded with a depth sensor similar to the Kinect
device. The dataset is described in the following paper.

Note that there is an error in the paper on the number of samples being used for the experiment. The number 402 in the paper is not correct. The correct number is 557. Out of the original 567 sequences in MSR Action3D Dataset, 10 sequences are not used in this paper's experiment because the skeletons are either missing or too erroneous.

Skeleton Data in screen coordinates (MSRAction3DSkeleton (20joints).rar) (Thanks to Yi Wen Wan, University of North Texas, for data cleaning and conversion). There is a skeleton sequence file for each depth sequence in the Action3D dataset. A skeleton has 20 joint positions (see the image for illustrations of the joint positions). Four real numbers are stored for each joint: u, v, d, c where (u,v) are screen coordinates, d is the depth value, and c is the confidence score. If a depth sequence has n frames, then the number of real numbers stored in the corresponding skeleton file is equal to: n*20*4.

This diagram shows the correpondence between the 20 points in the skeleton data and the joints (Thanks to Yu Zhong from AIT, BAE Systems for providing this diagram).

Human activity understanding from RGB-D data has attracted increasing attention since the first work reported in 2010. Over this period, many benchmark datasets have been created to facilitate the development and evaluation of new algorithms. However, the existing datasets are mostly captured in laboratory environment with small number of actions and small variations, which impede the development of higher level algorithms for real world applications. Thus, this paper proposes a large scale dataset along with a set of evaluation protocols. The large dataset is created by combining nine existing publicly available datasets and can be expanded easily by adding more datasets. The large dataset has 94 actions and is suitable for testing algorithms from different perspectives using the proposed evaluation protocols. Four state-of-the-art algorithms are evaluated on the large combined dataset and the results have verified the limitations of current algorithms and the effectiveness of the large dataset.
