| Abstract in different language: | A novel method for a representation of the optical system distortion using the discrete wavelet transform is proposed in this paper. Using the presented approach, virtually any complex distortion can be represented only with a small number of wavelet coefficients. Moreover, one can represent the distortion up to the resolution of one pixel or even finer. The experiments shown in the paper suggest that the introduced wavelet interpolation reconstructs distorted data very realistically. The proposed method was evaluated on two scenes comprising a projector and irregular surfaces using dataset of images of various type. |
