Comparative Study of Different Wavelet Based Interpolation Techniques

Images are used in many fields. One of the major issues of image is zooming. Zooming is used to increase the image resolution. Zooming is done through various interpolation methods. Interpolation is used for image scaling and zooming. Image zooming is process to extending an image to create a large image. There are several techniques of zooming. Wavelet transform is used due to the reason to obtain the image without distortion. This paper starts with the study of image zooming, their need and use of image zooming. This paper presents a review on different wavelet based interpolation techniques and their comparisons.
