Natural Scene Text Detection Based on Adaptive Color Clustering and Context Information
Natural scene text detection is an important task for image analysis and understanding.In this paper
a natural scene text detection method is proposed
using adaptive color clustering and context information analysis.Firstly
combining hierarchical clustering with self-learning strategy
we design an adaptive color clustering method
which learns clustering weights automatically and generates high character recall.Then
considering text in images usually containing several characters
we propose a character verification strategy based on image context information
which can guarantee high character recall and remove non-text components at the same time.Finally
characters are merged to text lines
and further post-processing is applied to generate final text detection results.Experiments on the ICDAR2013 publicly available dataset show that we obtain recall of 74.17%
precision of 83.40% and F-score of 78.52%.Compared with other text detection methods
our method obtains better text detection performance
