Webb1 jan. 2015 · When reconstructing a discrete representation of shape which has the most-similar gradient values with the measured ones, there is an implied assumption that all of the ignored higher order terms (no matter in what kind of forms, e.g. polynomials, Fourier cosine series, etc .) are really negligible. WebbIn this paper, an algorithm for image reconstruction from gradient data based on the Haar wavelet decomposition is proposed. The proposed algorithm has two main stages. First, the Haar decomposition of the image to be reconstructed is obtained from the given gradient data set. Then, the Haar wavelet synthesis is employed to produce the image.
