Abstract

Gurumukhi script is used for Punjabi language, which is a two dimensional composition of symbols with connected and disconnected diacritics. Handwritten Gurumukhi script has some complexities like connected, overlapped text lines, words and characters. It is one of the foremost issues for errors during the recognition process. Text segmentation is a challenging job in unconstrained writer independent handwritten document image processing. There is a huge need for research in the domain of Punjabi handwriting recognition to resolve these challenging problems. In this paper we have done a review on various methods for line, word and character segmentation in handwritten Punjabi document.

Keywords

Abstract

This paper proposes an overview of all the existing interpolation based image zooming techniques.There are various techniques ranging from traditional nearest neighbour, bilinear interpolation, cubic interpolation, spline interpolation to the fuzzy logic basedimage zooming techniques. Every interpolation techniqueshave its own advantages and disadvantages.In this paper, a comparison between various interpolation based image zoomingtechniques based on the PSNR is for various images.

Keywords
