[Full Text]



Suvi V, Vismi V



Key words: Discrete wavelet transform (DWT), bicubic interpolation, unsharpmasking (UM), Mother wavelet.



Abstract: The paper "Resolution Enhancement with Wavelet Unsharp Masking of Satellite Image" makes use of both wavelet and unsharp masking techniques. It is performed by using satellite image. By implementing this paper, increasing the resolution and removal of noisy content is achieved at the same time. Proposing an effective resolution enhancement techniques and then sharpening the image for removing the noisy content in that image. First DWT is applied to the input image, it decomposes the image into different frequency subbands apply bicubic interpolation to these subbands and inorder to remove the noisy contents in the image here it uses unsharp masking technique. Thus a resolution enhanced denoised image is obtained using wavelet transform.
