Text Detection in Images Based on Grayscale Decomposition and Stroke Extraction
Wei Fan, Jun Sun, Yutaka Katsuyama, Yoshinobu Hotta, Satoshi Naoi · 2009
A method of detecting text regions in images which combines grayscale decomposition and stroke extraction is proposed. By checking the consistency of the two text features, text-like connected components are grouped together to generate text line regions in the processed image. It shows good performance on efficiently detecting image text rendered in relatively complex backgrounds.
