Abstract :
This paper proposes a rapid method to accomplish text images correction from slant ones. In the method, the well-known projection algorithm is presented as basic principle. In traditional projection algorithm, the huge calculation for rotation leads to a slow processing speed. This improved method mainly targets at solving computational speed problem arising from projection algorithm, and this could be achieved by avoiding rotation calculation. The advantage of this algorithm lies in its manifest improvement on processing speed and a decrease in the requirement of text image integrality. When processing a large quantity of slant text image, the advantage is more obvious. The method could be applied for the real-time slant correction effectively and efficiently, although its fundamental principle is simple.
