ABSTRACT
Preprocessing is the first step used in all the document image analysis algorithms. A well organized preprocessing
could lead to better results of the analysis. This paper proposes a framework for preprocessing of document image
for analysis. The frame work uses four steps such as color image to grayscale conversion, enhancement of
grayscale image, binarizing the grayscale image and finally removal of clutter-noise. Horizontal and vertical
projections are used to detect possible locations of clutter noise in this work. Then foreground pixels are replaced
by background colored pixels based on the run length. The frame work provided better results for test images.
