Abstract (en)
[origin: WO2022128465A1] Method for reconstructing an image I of an object comprising the steps of: - acquiring (201), in a vector m, a number p of object imaging measurements; - determining (202) a first matrix AT equal to the product of a projection matrix P defining a set of projection vectors and of a dictionary matrix D formed of the components of an image decomposition basis, - seeking (203) a parsimonious solution x, of size N strictly greater than d, to the underdetermined linear system ATx=m - reconstructing (204) the image I through the product of the dictionary matrix D and of the vector x, which is the solution to said system.
