Wei Han · Computer Technology and Development · 2012
The integrated use of algorithms of image preprocessing,image segmentation,template matching,a ray-film character recognition technology is proposed based on connected domain characteristic and achieved in MATLAB.First,the image preprocessing is conducted,including image filtering,binarization and segmentation,get the character area to be identified.Then used connected domain processing method in the region for the characters to be identified,and analyzed connected domain characteristics of the character after the split in relation to the character templates.Finally,the template is matched and achieve character recognition using maximum likelihood method.The results show that the technique can effectively extract information out of the film characters,and has better robustness.
