基于色彩聚类的自然场景文本检测
Text detection from natural scene images based on color clustering
摘要
Abstract
Considering that the natural scene images have complex background and the text in them is usually various, a text detection method based on color clustering was proposed. The procedures are as follows. Firstly,K-means was utilized to group pixels in color images into five different color layers and the bounding-boxes of connected-components in every color layer were obtained. Some non-text components were removed by analyzing geometrical properties of the bounding-boxes. Subsequently, the scattered components were connected to form candidate text blocks according to their bounding-boxes’ geometrical properties and locations. Finally, text verification was performed by geometrical and edge density identifications. The experimental results show that the proposed method is feasible and effective.关键词
