A Text Localization Algorithm in Color Image via New Projection Profile

Abstract

Text data in image present useful information for automatic annotation, indexing and structuring of images. In this paper, we propose an approach to automatically localize horizontally texts appearing in color and complex images. First, an edge detection method using a wavelet transform is used to finding text in image. Second, the image is binarized. Third, a new filter is applying for removing disperses pixels and non text area. After that, a new projection profile is applying for estimating text regions. The experimental results show that the proposed method achieves a much higher accuracy than existing methods. The advantage of this algorithm is low computation for finding text.
