Discrete wavelet transform (DWT) can be used in various applications, such as image compression and coding. In this paper we examine how DWT can be used in image interpolation. Afterwards proposed method is compared with two other traditional interpolation methods. For the case of magnified image achieved by interpolation, original image is unknown and there is no perfect way to judge the magnification quality. Common approach is to start with an original image, generate a lower resolutiondoaj:2104aec0589b422498ab1e0a6ac79d06 fatcat:tuqvw5x7tzgdhar4tqk25pf2zm
