  • Introduction to Wavelets in Image Compression

    Wavelet transform is especially useful for transforming images. For this, we apply it twice according to the JPEG-2000 standard: first on columns, second on rows. Upon this, we deinterleave the image matrix, and possibly recursively transform each subband individually further. We can now import the standard benchmark picture, sized 512x512:
