Automatic text location in color images
Zhang Dong-ping · Journal of Zhejiang University(Engineering Science) · 2005
This work proposed a novel text location method that is suitable for World Wide Web search, color image indexing and video indexing. Image was first segmented into several blocks using multi-scale segmentation approach; then, texts in blocks were localized using connected component algorithm. A multi-color image decomposition method was utilized to extract connected components with uniform color. The location and range of text were obtained by clustering the adjacency connected components. The algorithm was applied to a test image database and showed promising results.
