In this these, we propose a text image stitching method based on OpenCV image processing library. The target of the research is to obtain a clear text image by stitching several partial text images which may be in different sizes or different skewed angles. We propose an algorithm to extract the text region for each text image, deskew the picture, and then stitch all images to get a single clear text image. We hope that the proposed method can be applied to build a convenient smartphone application to scan clear text images.
