A robust arbitrary text detection system for natural scene images

•We explore the property that pattern in both Sobel and Canny share the same feature.•New invariant symmetric features to classify text and non-text pixels correctly.•We exploit SIFT features to eliminate non-text components.•Ellipse growing to extract curved text lines using text representatives.•N...
