Automatic text location in complex color images using local color quantization
Pyeoung-Kee Kim · 2003
An efficient text location method in complex color images is proposed. To deal with characters on complex background colors, local color quantization is done separately for each color instead of all colors. A candidate text line is extracted merging connected components and confirmed using heuristics based on color profile. I tested the proposed method on complex book cover images and it is shown to be successful in extracting texts in complex color images.
