title = "Text detection from natural scene images using scale space model",
abstract = "A scale space based approach is proposed to detect text from natural scene images with complicated background. An edge map containing the edge information of four directions is obtained by Sobel operators. Character areas are detected by connected components analysis and are merged into candidate text regions. We construct a N-level scale space model and compute spatial responses to the Laplacian-of- Gaussian operator at these scale levels. The distribution of some strongest responses obtained from scale space model is employed to verify whether a candidate is a true text region or not. The experimental results demonstrate that the proposed method is able to effectively filter the nontext regions and locate text regions in natural scene images with complicated background.",
