Claim 11:
12. The system of claim 11, wherein:
the normalization module,
determines whether the text row/column image I is a horizontal or vertical text according to the width and height of the text row/column image I output from the external text detection module, and sets a horizontal/vertical flag according to the determination result; and
when the height of the text row/column image I is larger than γ times of the width of the text row/column image I, sets the horizontal/vertical flag to 0 which is corresponding to vertical text, and when the height of the text row/column image I is equal to or smaller than γ times of the width of the text row/column image I, sets the horizontal/vertical flag to 1 which is corresponding to horizontal text, and sets γ to a constant number of 1.5;
sets the image normalization width WI to 256, and sets the height HI to 64 in the case of the horizontal text; and
sets the image normalization width WI to 64, and setting the height HI to 256 in the case of the vertical text; and
a bilinear interpolation method is used for the image normalization.
