What is skew in image processing?

Skew detection is one the first operations to be applied to scanned documents when converting data to a digital format.

Its aim is to align an image before processing because text segmentation and recognition methods require properly aligned next lines.

The skew angle is obtained by searching for a peak in the histogram of the gradient orientation of the input grey- level image. The skewness of the document is corrected by a rotation at such an angle. The slant of characters can also be detected using the same technique, and can be corrected by a shear operation.
