Paper Abstract

In the note, several wavelet-based image processing algorithms are presented. Denoising algorithm is derived from the Donoho's thresholding. Rescaling algorithm reuses sub-division scheme of the Sweldens' lifting and a sensor linearization procedure exploiting system identification algorithms developed for nonlinear dynamic systems. Proposed autofocus algorithm is a passive one, works in wavelet domain and relies on properties of lens transfer function. The common advantage of the algorithms is that they can easily be implemented within the JPEG2000 image compression standard encoder, offering simplification of the final circuitry (or the software package) and the reduction of the power consumption (program size, respectively) when compared to solutions based on separate components.
