Abstract 

 Our dataset has a total of 8 actions, 7 people(P1-P7), and 3 experimental environments(Room-A,Room-B,Room-C). There are a total of 3 directions in each environment, with 5 samples of each action taken for each person in each direction, so the number of samples is 360(samples/person)*7 = 2520.

    We use two environments(Room-A and Room-B) and 5 people(p1-p5) as training and validation, 150(samples/action)*8(actions) = 1200,the Classes in front of  the symbol (_), followed by the serial number, The 1-75 samples are taken from the training set and the 76-150 samples are taken from the val set. i. e,the images of action Bow are named 0_1~0_75(train_bow),0_76~0_150(val_bow).

    We take the last environment(Room-C) and 2 people(P6 and P7) as a test, 30(samples/action)*8(actions) = 240.Image name naming rules: the symbol (_) in front of the category, followed by the serial number, where the test set of 30 samples per action, each category is sorted according to 1-30, i. e,the images of action Bow are named 0_1~0_30(test_bow).

Each action is classified as follows:

0 is bow

1 is boxing

2 is falldown

3 is handup

4 is stand

5 is squat

6 is sit

7 is walk

 

Instructions: 

Our dataset has a total of 8 actions, 7 people(P1-P7), and 3 experimental environments(Room-A,Room-B,Room-C). There are a total of 3 directions in each environment, with 5 samples of each action taken for each person in each direction, so the number of samples is 360(samples/person)*7 = 2520.

We use two environments(Room-A and Room-B) and 5 people(p1-p5) as training and validation, 150(samples/action)*8(actions) = 1200,the Classes in front of  the symbol (_), followed by the serial number, The 1-75 samples are taken from the training set and the 76-150 samples are taken from the val set. i. e,the images of action Bow are named 0_1~0_75(train_bow),0_76~0_150(val_bow).The environment(Room-C) and 2 people(P6 and P7) are used as a test, 30(samples/action)*8(actions) = 240.

 

Image name naming rules: 

the symbol (_) in front of the category, followed by the serial number, where the test set of 30 samples per action, each category is sorted according to 1-30, i. e,the images of action Bow are named 0_1~0_30(test_bow).

 

Each action is classified as follows:

0 is bow

1 is boxing

2 is falldown

3 is handup

4 is stand

5 is squat

6 is sit

7 is walk
