How to calculate the Compression ratio of Wavelet transformed image?? - Yeasin Razib - Sep 7 7:36:43 2007

  I'm working with image compression with wavelet transform using different
types of wavelets in MATLAB.I did multi-resolution decomposition and
reconstructed the image.I've calculated the PSNR and MOS. I didn't encode the
image into file.Is it possible to calculate the compression ratio without
encoding (like in DCT) ? If, then whats the procedure?
  If anyone has any idea plz share it with me and ur cooperation will be highly
  Thanking u,
  Razib, Siam
