Abstract
The slant is one of the main sources of handwritten text variability. The slant is the clockwise angle between the vertical direction and the vertical text strokes. A well formalised and fast method to estimate the slant angle is presented. The method is based on the observation that the columns distribution of the vertical projection profile presents a maximum variance for the non slanted text. A comparative with Sobel operators convolution method and the Idiap slant method is provided.
