Abstract
A non-conventional text character extraction technique, called Horizontal-Vertical Projection (HVP), has been used for feature extraction of numerous alpha-numeric symbols. In an earlier paper, a classification process using 1-D Fourier Transformation was used. This limited the success of the HVP character rcognition ratio, however. In this paper, a 2-D feature extraction technique is presented showing the improvements of the HVP character-recognition ratio over the previous approach.
