             abstract = "The skew correction of scanned document images is an important 
                         step toward an automatic recognition system. Several techniques 
                         have been developed to estimate the skew angle of a scanned 
                         document. However, most of these techniques have the problem of 
                         expensive computational costs. A variation of a fast method based 
                         on parallelograms covering is presented in this article. The 
                         objective is to obtain lower computation time and provide a way to 
                         work well over noisy images and also over different layouts 
                         containing non-text areas with no decrease in performance. 
                         Experimental study with different databases achieved results that 
                         overcome previous techniques.",
