Mouse Trajectory Recognition Technology Based on BP Neural Network
Lei Zhou · Computer Knowledge and Technology · 2013
Trajectory recognition is a classification problem,in this work,the BP neural network technology is adopted to achieve the recognition of the trajectory of the mouse.For artificially generated training samples is time-consuming and ineffi cient,this paper proposed a novel method to expand the training set using transformed version of the original input patterns(ex tract angle feature,and then add noise to the original trajectory).Finally,training 11 types of trajectories,and test the performance of the BP neural network,the experimental results show that the recognition rate of 92.9%.
