Two methods for hand-drawn shape recognition

TU Hong-lei (College of Information Technology and Software Engineering, Beijing Normal University, Zhuhai 519085, China)  
Hand-drawn shapes are widely used in human machine interactions. Their recognition algorithms is researched. For the online recognition, the algorithm of normalized Fourier transform descriptor is used. Via computing the continuous Fourier transform descriptor of the lines of the drawing trace, matching is based on the normalized FFT descriptors of the test samples and the training samples. For the off-line recognition, the principal component analysis method is applied. By extracting the principal orthogonal subspace of the training samples, the recognition is accomplished by computing the samples' projections onto the subspace and then comparing them. The recognition system is implemented in Java, which is a platform independent language. The lab results are presented and the comparison of the two algorithms is provided.
