It has been observed that the frequency response of Gabor ﬁlter is similar to human visual system. The response of Gabor ﬁlter to an image is determined by the 2-D convolution operation. In general, the ﬁlter will convolve with the input image signal and a Gabor space is generated. If I(x, y) is an image and G(x, y, f, ϕ) is the response of a Gabor ﬁlter with frequency f and orientation ϕ to an image on the (x, y) spatial coordinate of the image plane [19, 22].

Finally, a Line-level dataset of total 782 document images with a distribution of 100 Bangla, 100 Devnagari, 102 Kannada, 100 Malayalam, 100 Oriya, 90 Roman, 90 Telugu, and 100 Urdu images are prepared (sample shown in Fig. 5). Document digitization was done using HP flatbed scanner and stored initially at 300 dpi. Binarization was done using existing two-stage-based algorithm that was discussed already. Finally, experimentation was carried out on the prepared dataset (sample shown in Fig. 5). Md.
