In-Air Hand-Drawn Number and Shape Dataset

<div><div>This dataset contains in-air hand-written numbers and shapes data used in the paper:</div><div>B. Alwaely and C. Abhayaratne, "Graph Spectral Domain Feature Learning With Application to in-Air Hand-Drawn Number and Shape Recognition," in IEEE Access, vol. 7, pp. 159661-159673, 2019, doi: 10.1109/ACCESS.2019.2950643.</div><div><br></div><div>The dataset contains the following:</div><div>-Readme.txt</div><div>- InAirNumberShapeDataset.zip containing</div><div>-Number Folder (With 2 sub folders for Matlab and Excel)</div><div>-Shapes Folder (With 2 sub folders for Matlab and Excel)</div><div><br></div><div>The datasets include the in-air drawn number and shape hand movement path captured by a Kinect sensor. The number sub dataset includes 500 instances per each number 0 to 9, resulting in a total of 5000 number data instances. Similarly, the shape sub dataset also includes 500 instances per each shape for 10 different arbitrary 2D shapes, resulting in a total of 5000 shape instances. The dataset provides X, Y, Z coordinates of the hand movement path data in Matlab (M-file) and Excel formats and their corresponding labels.</div><div><br></div><div>This dataset creation has received The University of Sheffield ethics approval under application #023005 granted on 19/10/2018.</div></div><div><br></div>
