1. A method for projective correction of an image containing at least one text portion that is distorted by perspective, the method comprising the steps of: image binarization, wherein said image is binarized; connected component analysis, wherein pixel blobs are detected in said at least one text portion of said binarized image; horizontal vanishing point determination, comprising estimating text baselines by means of eigenpoints of said pixel blobs and determining a horizontal vanishing point of said at least one text portion by means of said text baselines; vertical vanishing point determination, wherein a vertical vanishing point is determined for said at least one text portion on the basis of vertical features thereof; and projective correction, wherein said perspective in said image is corrected on the basis of said horizontal and vertical vanishing points.
