Most of the text localization techniques are sensitive to text color, size, font and background clutter. They simply exploit the general segmentation rules or the prior knowledge about the text shape/size. As, inherently, a text consists of strokes of different sizes and orientations, so the concept of Stroke Filter is much more effective, particularly where text segmentation is taken into consideration. The problem with traditional stroke filter lies in its fixed width and is capable of segmenting strokes of predefined width. The proposed method uses adaptive stroke filter which can localize text regions, having varying stroke width, within camera captured images. The method is verified by experiment on a database containing 600 images.
