A Combined Edge and Connected Component Based Approach for Kannada Text Detection in Images
Shahzia Siddiqua, C. Naveena, Sunilkumar S. Manvi · 2017
This paper presents an approach for Kannada text detection from scene images. The sturdiness of our system comes from three facets. Initially, we used a morphological edge detection method. In this a threshold level is determined resulting in an edge image. Secondly a text feature filtering method is applied which removes maximum non-letter components. Also, the method results in majority of letter components that are within the range of mean height of the residual bounding boxes. Finally a text region binarization method is applied using a threshold from the residual bounding boxes. The performance of the proposed method was tested on our own collection of 200 kannada images and the results are satisfactory.
