Binarization, Text detection, Ground truth


For each image, a manually binarized and verified image is provided on which the text pixels are marked in black while the rest of pixels are marked in white. An automatic binarization method for ground truthing was used prior to the manual verification of the binary images in order to speed up the process. The automatic binarization method will be described in a paper (to be submitted to ICDAR’13).
