I think this paper was part of it, which showed that the advantages of fractal image compression could equivalently be achieved with smooth wavelets and efficient representation of zerotrees, except with a lot more speed and flexibility (sorry no PDF): https://www.researchgate.net/publication/5585498_A_wavelet-based_analysis_of_fractal_image_compression https://www.researchgate.net/publication/5585498_A_wavelet-b...
