In order to solve the problem of low precision in existing natural scene text detection algorithm
a text detection algorithm based on improved convolutional neural network and the feature of text lines was proposed. Firstly
the enhanced maximally stable extreme region (MSER) was used to extract connected components of the image and isolated connected regions were obtained by pruning method. Secondly
an improved convolutional neural network (CNN) was used to eliminate non-character regions and obtain candidate character regions. Thirdly
an algorithm based on the feature of text lines for constructing multi-oriented candidate text lines was proposed to detect arbitrary oriented and curved scene text. Finally
C4.5 decision tree algorithm was applied to classify candidate text lines. Experiments were carried out on ICDAR2013
ICDAR2015 and MSRA-TD500 datasets. Experimental results show that the algorithm can significantly improve the precision and recall of text detection in natural scenes
and is suitable for text in any direction
language and font.
