Text Detection and Pose Estimation for a Reading Robot
Marius Bulacu, Nobuo Ezaki, Lambert Schomaker · InTech eBooks · 2008
One very important advantage of using CoCos for text detection is that they naturally allow the analysis to take place across scales. In this approach, scale does not represent such a problematic issue because the CoCo extraction process is scale independent. CoCos give a prompt, but rather imperfect, hold to the structures present in the image and CoCo selection
