Motion blur usually happens to image recording systems. Nowadays, this rich source of data is mostly dismissed in favor of image restoration. We introduce a novel approach for estimating kinematic quantities such as direction and speed of motion using the Discrete Cosine Transform (DCT). The mean relative error of our DCT PSeudo Cepstrum for speed estimation was 5.15%. The DCT frequency analysis is more accurate than all competitors evaluated.
