Abstract :
A projective image registration algorithm, oriented to consumer devices, is proposed. It exploits a "multi-resolution feature based method" for estimating the projective parameters through a 2D Daubechies discrete wavelet transform (DWT). The algorithm has been fully tested with real image sequences acquired by CMOS sensors and compared to other registration techniques. The obtained results highlight the accuracy of the registration parameters.
