How to calculate the Compression ratio of Wavelet transformed image??

Started by Yeasin Razib September 7, 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 appreciated.

Thanking u,
