Fast sparse fractal image compression. [PDF]
PLoS One, 2017 As a structure-based image compression technology, fractal image compression (FIC) has been applied not only in image coding but also in many important image processing algorithms. However, two main bottlenecks restrained the develop and application of FIC for a long time. First, the encoding phase of FIC is time-consuming.

Fractal-wavelet image denoising revisited [PDF]
IEEE Transactions on Image Processing, 2006 The essence of fractal image denoising is to predict the fractal code of a noiseless image from its noisy observation. From the predicted fractal code, one can generate an estimate of the original image. We show how well fractal-wavelet denoising predicts parent wavelet subtress of the noiseless image.

An Improved Robust Fractal Image Compression Based on M-Estimator
Applied Sciences, 2022 In this paper, a robust fractal image compression method based on M-estimator is presented. The proposed method applies the M-estimator to the parameter estimation in the fractal encoding procedure using Huber and Tukey’s robust statistics.
