Summary: In order to get an interpolated image with a better visual result and higher SNR, and to overcome the shortcomings of blur effects when interpolating with the scalar wavelet transform, a novel adaptive image interpolation algorithm is proposed. By transforming the images into the multiwavelet domain and using the fractal dimensions of high frequency bands, with the low-resolution image and the high frequency bands of one level multiwavelet transform for the image, every band of the two level multiwavelet transform for high-resolution images is obtained adaptively. Through the two level inverse multiwavelet transform, a more distinct interpolated image can be obtained.
