This paper proposes the IPN Hand dataset, a new benchmark video dataset with sufficient size, variation, and real-world elements able to train and evaluate deep neural networks for continuous Hand Gesture Recognition (HGR). With our dataset, the performance of three 3D-CNN models is evaluated on the tasks of isolated and continuous real-time HGR. Since IPN hand contains RGB videos only, we analyze the possibility of increasing the recognition accuracy by adding multiple modalities derived from RGB frames, i.e., optical flow and semantic segmentation, while keeping the real-time performance.
The subjects from the dataset were asked to record gestures using their own PC keeping the defined resolution and frame rate. Thus, only RGB videos were captured, and the distance between the camera and each subject varies. All videos were recorded in the resolution of 640x480 at 30 fps.
Each subject continuously performed 21 gestures with three random breaks in a single video. We defined 13 gestures to control the pointer and actions focused on the interaction with touchless screens.
Description and statics of each gesture are shown in the next table. Duration is measured in the number of frames (30 frames = 1 s).
| id | Label | Gesture | Instances | Mean duration (std) |
|---|---|---|---|---|
| 1 | D0X | Non-gesture | 1431 | 147 (133) |
| 2 | B0A | Pointing with one finger | 1010 | 219 (67) |
| 3 | B0B | Pointing with two fingers | 1007 | 224 (69) |
| 4 | G01 | Click with one finger | 200 | 56 (29) |
| 5 | G02 | Click with two fingers | 200 | 60 (43) |
| 6 | G03 | Throw up | 200 | 62 (25) |
| 7 | G04 | Throw down | 201 | 65 (28) |
| 8 | G05 | Throw left | 200 | 66 (27) |
| 9 | G06 | Throw right | 200 | 64 (28) |
| 10 | G07 | Open twice | 200 | 76 (31) |
| 11 | G08 | Double click with one finger | 200 | 68 (28) |
| 12 | G09 | Double click with two fingers | 200 | 70 (30) |
| 13 | G10 | Zoom in | 200 | 65 (29) |
| 14 | G11 | Zoom out | 200 | 64 (28) |
| All non-gestures: | 1431 | 147 (133) | ||
| All gestures: | 4218 | 140 (94) | ||
| Total: | 5649 | 142 (105) |
