| Abstract: | Independent Component Analysis(ICA)is applied to video frame sequence processing.A novel scheme for the detection and location of the text in video based on ICA algorithm is proposed.The new algorithm uses wavelet transformation to extract independent components.The simulation results prove that compared with the conditional algorithm,the algorithm can eliminate the background information and improve the precision of the caption location.Thus the algorithm is stronger robustness. |
| Keywords: | text in video caption detection caption location independent component analysis |
