A simple method of identifying the characters of ancient Tamil inscription. This method is most specifically proposed for the Vattezhuthu type of Tamil characters. This type of characters were used from 8th to 15th century is not similar to modern Tamil and cannot be understood easily. These inscriptions contain some of the important information such as life of kings, their contributions to the society and also information related to medical field. Hence in an effort to retrieve information from these inscriptions and also from the written scripts this paper has been developed. This method translates the ancient character to modern Tamil which can be understood by todays’ generation using non-subsampled contour-let transform (NSCT) and probabilistic neural network (PNN). Median filter is used for removing noise in the image.
