}The paper presents a method to detect table regions in document images by identifying the column and row lineseparators and their properties. In order to enhance dark thin line-like structures, the input image is first smoothed with a Gaussian filter followed by gray-scale morphological black-hat operation. This pre-processed image is adaptively-thresholded and a run-length approach is employed to extract horizontally and vertically-aligned lines. From each group of intersecting horizontal and… CONTINUE READING
