Border removal

Border removal process aims at enhancing the document images by automatically detecting and cutting out noisy black borders as well as noisy text regions appearing from neighbouring pages. It is based on projection profiles combined with a connected component labeling process and signal cross-correlation in order to verify the detected text areas. We present the output of this process (BordRem_1_Output.tif, BordRem_2_Output.tif, BordRem_3_Output.tif) when starting from already binarized images (BordRem_1_Input.tif, BordRem_2_Input.tif, BordRem_3_Input.tif).
