In this paper we present a new approach to deblur the effect of atmospheric turbulence in the case of long range
imaging. Our method is based on an analytical formulation, the Fried kernel, of the atmosphere modulation
transfer function (MTF) and a framelet based deconvolution algorithm. An important parameter is the refractive
index structure which requires specific measurements to be known. Then we propose a method which provides a
good estimation of this parameter from the input blurred image. The final algorithms are very easy to implement
and show very good results on both simulated blur and real images.
