Abstract

A new adaptive algorithm for image zooming with edge preservation is proposed. The 4-point interpolation scheme is introduced to resample the original low-resolution image. By using the wavelet transform and inverse wavelet transform, edges in original image are extracted and restored to the final high-resolution image automatically.
