The contrast reduction of remote sensing images is mainly because of the reduction of the modulation transfer function(MTF)of the optical system.And MTF represents the characteristic of the light energy distribution of the optical system.By analyzing the theory of contrast reduction

this paper presents a remote sensing image enhancement method based on energy distribution.Firstly

the image energy at the low frequency domain is decreased

and then the decreased image energy is allocated to the high frequency domain to obtain the enhancement result.The experimental results demonstrate that the proposed method is simple and effective

which is feasible for remote sensing image enhancement.
