This paper presents a novel procedure for localizing text on scene photos. It takes advantage of the fact that text should present some contrast in comparison with the background, in order to be distinguished by the human eye. A procedure of binarization is applied in order to create appropriate images for the text detection. The connected components of the image are extracted and some heuristic rules...
In this paper, two techniques are presented, appropriate to detect the text main body size in a document image. One measures it directly, while the other estimates the baselines first. Both are segmentation free. Experimental results are presented over a collection of handwritten text, as well as for a small collection of 10 printed document images, in order to give more objective results.
