Abstract [en]

Time-warped polynomials provide a way of generating bases that is optimized to the characteristics of a particular signal. In this master thesis, the time-warped polynomial transform and its possible applications in the field of video compression is analyzed. It was found that the optimal warped transform suggested by W. Philips does not work well for image data, but that a modification gives much better results. The main weaknesses of the transform in the context of video compression is the need for computing power and the difficulties to apply the transform on two-dimensional data.
