Abstract

Gaussians are useful in multiscale representation of video data. An algorithm is presented which approximates a sequence of uniformly spaced single-valued data by a sum of Gaussians with a prescribed accuracy. The scale-space image [6] of the data is used to estimate the number of Gaussians and their initial parameters. The Marquardt algorithm (J. SIAM 11(2), 1963, 431-441) is then used to optimize the parameters.

    Practically, Javadpour [31] used the integral of Gaussian function to fit the gas desorption volume curve and obtained a good fitness. Mathematically, Goshtasby and Oneill [39] had proven that a sequence of spaced points with associated data values could be fitted by a sum of Gaussian function. In fact, the Gaussian function has been widely used in other fields such as flow injection analysis [40,41], chromatographic analysis [42] and thermal diffusion separation [43], and good results are obtained.
