Abstract
In the document analysis system or the understanding system[1,2], the rotation of the document's image will cause optical character recognition error. Then the document must be scanned and recognized again. This phenomenon will degrade the performance of the automatic document input system. In this paper, we propose a method to estimate the unexpected rotational angle of the image. And we suggest using the pipelined CORDIC array processor architecture to rotate the image back quickly. Thus the performance of the automatic document input system will increase.
