A Novel Text Detection Approach Based on Multi-Structure Element of Morphology

摘要

A novel text detection method based on multi-structure elements of morphology is presented to extract text lines in this paper. Firstly, a multi-structure elements of morphology-based scheme is executed to extract contrast edges from color images. Then connected component analysis and a cascade classification scheme are adopted to obtain candidate text lines. Finally, a projection based method is applied to extract character characteristics to filter out impossible text lines. Experimental results indicate that the proposed method can effectively detect text lines in different font-size, language and background complexity.
