Abstract Aiming at the problem of extracting text from images with complex background, a method based on conditional random field is proposed. The proposed method integrates various features and takes context information into account, thus it can extract text information effectively from images. The text extraction performance in different color spaces and with different features is compared. Experimental results demonstrate the validity of the proposed method.
