The purpose of this work is to introduce a new mathematical tool to analyze image data coming from surveys. Built using Chebyshev polynomials and Fourier series, cheblet bases have shown to be highly powerful to model a huge variety of galaxies with different morphologies and features, displaying a better behavior than other well-know techniques as, for instance, the fitting by analytical profiles (Sersic, exponentials...) or shapelet bases. Several applications of this new method will be also displayed, as the use of the coefficients for the calculation of morphological parameters or the galaxy cluster modeling.
