In this paper, the authors present a new skew detection and correction technique using FFT and median filtering. It is found that there are many techniques based on skew correction which have been proposed so far by different researchers. It has been found that the most of existing techniques introduce artifacts while doing the skew correction. So, to overcome this problem an integrated approach is presented in this paper. The proposed algorithm is planned and implemented in Matlab using image processing toolbox.
