CONCLUSIONS

The experience of researching image compression techniques has been very enlightening. Most image compression techniques are simple to understand but more difficult to implement. Moreover while the techniques can help compression by transforming information into another domain, it is clear that good quantization techniques are key. DCT is a faster code that has good compression possibilities. The Haar wavelet, though it is not the most effective wavelet to use for compression, achieves admirable compression in conjunction with adaptive or statistical quantization.
