I was looking the project on text detection up on GSOC this year. I'm immensely interested in the field of machine learning and computer vision. I recently completed a course on machine learning on coursera offered by the stanford university. I just wanted to know what the pre requisites are for this text detection project, i.e., what I should know before I can start reading the papers on Real-time scene text localization and recognition and also the one on stroke width transformation.
