In-Air Hand-Drawn Number and Shape Dataset

This data set contains in-air hand-written numbers and shapes data used in the paper "Graph Spectral Features for In-Air Hand-Drawn Number and Shape Recognition" submitted to IEEE Trans. Multimedia submitted in November 2018.<br>This data set contains the following:-Readme.txt- InAirNumberShapeDataset.zip containing<br> -Number Folder (With 2 sub folders for Matlab and Excel) -Shapes Folder (With 2 sub folders for Matlab and Excel)<br>The data sets 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 data set provides X, Y, Z coordinates of the hand movement path data in Matlab (M-file) and Excel formats and their corresponding labels. <br>This dataset creation has received The University of Sheffield ethics approval under application #023005 granted on 19/10/2018.

本数据集包含2018年11月提交至《IEEE多媒体汇刊（IEEE Trans. Multimedia）》的论文《Graph Spectral Features for In-Air Hand-Drawn Number and Shape Recognition》中所使用的空中手写数字与图形数据。
本数据集包含以下内容：
- Readme.txt
- InAirNumberShapeDataset.zip压缩包，其中包含：
- 数字文件夹（下设Matlab与Excel两个子文件夹）
