The Open-Closed Depth Hand Dataset (OCDH) is composed of samples of a pair of classes representing open or closed hand poses. Each sample is given as a depth (scalar) image and a binarized image. A large and diversified hand pose image dataset composed by 160,000 samples was collected from 20 individuals (15 men and 5 women). From each subject, depth images of the whole body were collected using a Kinect v1 sensor at 640 × 480 resolution. To improve diversity, individuals were asked to vary its global body pose as much as possible, and capture was performed in environments with different backgrounds. From the depth images, a cropped hand was extracted and stored in the dataset. As the distance from the hand to the sensor is variable, the cropped image resolution varies greatly. The database was originally collected to evaluate the methodology presented in the paper "Bruno Lima, Givanildo L. N. Júnior, Lucas Amaral, Thales Vieira, Bruno Ferreira and Tiago Vieira, 'Real-time hand pose tracking and classification for natural human-robot control', In International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, VISAPP 2019."
