\udArc-form-text is an artistic-text which is quite common in several documents such as certificates, advertisements and history documents. OCRs fail to read such arc-form-text and it is necessary to transform the same to linear-form-text at preprocessing stage. In this paper, we present a modification to an existing transformation model for better readability by OCRs.The method takes the segment arcform-text as input.Initially two concentric ellipes are approximated to enclosed the arc-from-text and later the modified transformation model transforms the text in arc-form to linear-form. The proposed method is implemented on several upper semi-circular arc-form-text inputs and the readability of the transformed text is analyzed with an OCR
