Sangheeta Roy, Partha Pratim Roy, Palaiahnakote Shivakumara, Georgios Louloudis, Chew Lim Tan, Umapada Pal
2013 2013 2nd IAPR Asian Conference on Pattern Recognition  
Recognition of curved text in natural scene image is a challenging task.  ...  The proposed approach has been tested on different natural scene benchmark as well as video databases, e.g. ICDAR-2003competition scene images, MSRA-TD500 and NUS.  ...  However, these methods are developed for scanned images but not for scene text in natural scene images. Therefore, these methods cannot be applied on scene text directly due to complex background.  ...
