I have implemented Haar wavelet transform in 2D using vectors from complex base numeral systems - making regions fractals: https://github.com/JarekDuda/FractalWavelets

Here are examples of obtained block structures ( values -> Haar coefficients, then trim high frequencies: set them to zero, then coefficients -> values. The rest of the picture has remained unchanged ):

What do you think of such transform for lossy image compression?
Have you heard of similar approaches?
